Interns Summer in Review, Part 4: So, what do YOU do?

2014 Interns Ariel Kaluzhney and Madeleine Ball

An Explanation of NEON鈥檚 Airborne Observation Platform and Cyber Infrastructure through New Eyes

By Ariel Kaluzhny and Madeleine Ball

After spending time together in NEON鈥檚 summer internship program, Ariel Kaluzhny (a computer science student) and Maddy Ball (an environmental science major) learned a lot about their NEON projects, explored a good bit of Colorado and became great friends. But, coming from such different perspectives, what they didn鈥檛 know was what their new friend did every day at NEON.  So they got together and decided it was time to learn a little about each other鈥檚 departments.

This blog is about their quest. To start, they wrote first impressions of each other鈥檚 department based solely on prior knowledge from time spent together outside the office.  Next, they interviewed each other and each other鈥檚 mentor.  Finally, they shadowed each other to see first-hand what they did day-to-day.  After all this, they sat down again and wrote their stories. Enjoy!

Student Profiles

Ariel Kaluzhny

Cyber Infrastructure Intern

School/Year: Wesleyan University, Class of 2016

Major: Computer Science and Economics

Hometown: Newton, MA

Why NEON: NEON鈥檚 description of the internship program seemed like a really good fit for me. It is geared towards students going into their junior or senior years of college and puts an emphasis on learning, which is really important to me in my first internship. Since NEON partners with other internship programs it has been so easy to meet new people and make friends. And then there鈥檚 the fact that it鈥檚 in Boulder!!

Ariel鈥檚 First Impressions of A.O.P: From what I have gathered, the Airborne Observation Platform (AOP) department collects data on a large scale by flying planes over NEON sites across the United States. They collect LiDAR data, and I know that Maddy uses a program called ENVI in order to examine or analyze image data. She鈥檚 basically 鈥渓ooking at pretty pictures all day.鈥�


Madeleine (Maddy) Ball

Airborne Observation Platform Intern

School/Year: Tufts University, Class of 2015

Major: Environmental Science and Earth and Ocean Sciences

Hometown: Mill Valley, California

Why NEON: I wanted a summer internship where I could pursue my passion for science and the outdoors while learning and exploring career options.  NEON has provided all that and so much more.  I am gaining skills in remote sensing, learning about the monumental task NEON is taking on throughout the country, making connections鈥� and having some fun on the side!

Maddy鈥檚 First Impressions of C.I.: I think Cyber Infrastructure takes all the data that other teams collect and does things to make it more accessible to the public.  I know it involves 鈥渨riting code鈥� because that鈥檚 what Ariel talks about all the time.  Beyond that, I鈥檓 not sure鈥�

Interviews of Each Other

Maddy: What are the overall goals of your department?

Ariel: The goal of Cyber Infrastructure (CI) is to create NEON鈥檚 website and data portal. This means the team is in charge of converting all of the data collected across the observatory into something that will be useful to the scientific community. They are also trying to make it so that, once NEON鈥檚 construction phase is complete, data can be converted and available through the data portal in real time.

Maddy: Within your department, what team are you on?

Ariel: I am on a team called the Data Processing Management Service (DPMS). We are in charge of converting raw data from the field into higher level data products that can be used by outside scientists, and students. DPMS implements Algorithm Theoretical Basis Documents (ATBDs) provided by NEON scientists. These documents describe how to change the raw data into higher level data.

Maddy: What are you working on this summer?

Ariel: I am working on two projects this summer to help the DPMS team. DPMS is constantly working on updating and adjusting the implementation of the algorithms that transform raw data into Level 1 data.  My first project is to create tools such as graphs, difference files, and summary statistics to show possible differences in outputs before and after a code change. My second project is working on implementing the algorithms for the 2D Wind anemometer.

Maddy: How have your expectations been met/not been met?

Ariel: First, I didn鈥檛 expect the CI department to be so large and to have so many different tasks and projects going at once. I also didn鈥檛 expect everyone in the department to know what everyone else is doing, which is part of a new process the CI department is using called Agile. Every morning there is a short 鈥淪tand-Up鈥� meeting during which everyone quickly shares what they worked on the day before, what they will work on that day, and whether they are blocked in some way. It has been nice to see the department together and aware of all the different projects within the team.

Maddy: Sketch out a day in the life of a CI Intern.

Ariel: My daily schedule usually goes like this:

8-9:30: Make sure that what I worked on the day before is correct and finished so that I can confidently speak at the Stand-Up.

9:30-10: Stand-Up Meeting

10-5: Spend time at my computer working on writing and testing code or documenting what I have done.

And of course, I have lunch with Maddy at noon every day! 

Maddy: Do you have a fun story from your department?

Ariel: One day at our daily stand-up meeting, someone was asked how his meeting with the science group went. His response was that they basically wanted him to draw 7 transparent perpendicular lines in blue ink; everyone in the department simultaneously started chuckling. Although it sounded weird, I got the reference - it was a line from a comedy show from a while back. It was endearing to see all of these different people understand and appreciate this obscure comedy reference. It also really made me feel like a member of the group.

Ariel: What are the overall goals of your department?

Maddy: The overall goal of the Airborne Observation Platform (AOP) is to collect and provide aerial data that is calibrated and consistent over a large scale.  AOP will fly over all NEON sites once a year with airplanes equipped with LiDAR, spectrometers, digital cameras, and a GPS/IMU.  The team works together to calibrate devices, atmospherically correct images, and ultimately provide data that is easily accessible and free to the public.

Ariel: Within your department, what team are you on?

Maddy: Unlike CI, the AOP teams are less defined. There is the flight operations team, which is responsible for running all equipment on the plane, but beyond that, my sense is that each person contributes something to the overall department goal.

Ariel: What are you working on this summer?

Maddy: I'm looking at data AOP collected in June 2013 from Domain 17, the Pacific Southwest.  The images cover the San Joaquin Experimental Range (see the picture at right) near Fresno, California.  I am using data collected from our airplane, from AVIRIS (another hyperspectral sensor), and from Landsat (a well-known satellite) to create normalized difference vegetation indices (NDVIs) of the area.  NDVIs show the distribution and concentration of vegetation in any given location.  I will compare outputs from each sensor to show future data users how NEON data compares to these other well-known and trusted sensors. 

Ariel: How have your expectations been met/not been met?

Maddy: Coming into this program, I wasn鈥檛 quite sure what to expect.  Though I did already have some experience working with hyperspectral imagery, I had never applied it in a formal work setting.  I expected to work independently and problem-solve on my own.  In that sense, my expectations have been met because every day seems to bring a new challenge.  I spend a lot of my time looking at images on a computer which also aligns closely with what I expected.  I expected to be in the office every single day so one of the biggest surprises was how much time I got to spend in the field collecting ground data and collecting calibration data.  That has been fun as well!

Ariel: Sketch out a day in the life of an AOP Intern.

Maddy: Most days start off the same way.  I come in, check my emails, and pour myself a steaming cup o鈥� joe.  From there, it really depends on the day.  Some days, I have meetings to attend.  Other days, I work in ENVI playing around with NEON data.  I spent one day at the airplane hangar working to collect ground support data for the flight operators.  The bottom line is, every day in the life of an AOP intern is a little different鈥hich I love!

Ariel: Do you have a fun story from your department?

Maddy: It鈥檚 a pretty fun department so it鈥檚 tough to choose one. I guess one that I found pretty cool is our department鈥檚 use of coconut oil鈥�. No we don鈥檛 suntan or make granola in AOP! We use coconut oil in our spectrometer 鈥� for cooling! 鈥� due to its special temperature properties. It鈥檚 a method thought of and designed by our AOP engineers.


Interviews with Mentors

Francois Pradeau

Team Leader, Software Applications Engineer (Ariel's Mentor)

 How would you describe CI?

CI is many different things and that is why it is hard to describe in one sentence.  I will break it down into our deliverables.  We contribute data products, websites, and support for the observatory in many things such as monitoring assets.

What is your role within CI?

I am the team lead for the CI group in charge of generating higher-level data products (DPMS) from the raw data.

What do you like about working at NEON?

What I like most is the diversity of the science, the scientists, and the people I work with.  I didn鈥檛 always have that and it is just awesome to one day sit down with someone working with small mammals and another day with someone working on AOP.

What is something unique about the department?

The diversity of our people: we have scientific programmers, website designers, people in Maximo, PDA people, and more.  We really are this microcosm of almost all the software out there.

How did you get in to this field?

To me, mathematics is the Holy Grail. But, you can鈥檛 make a career out of that so I looked in to computer science and I loved it.  My work is problem solving, which I find very cool.

If CI were a food, what would it be and why?

I am French, so of course I will choose something French (laughs).  I would choose Boeuf Bourguignon which is a sort of meat in wine dish.  It is CI because it is hearty, not light, and, oh what鈥檚 the word鈥ependable!

Nathan Leisso

AOP Calibration Scientist (Maddy's Mentor)

How would you describe AOP?

AOP provides a unique ability because of its scaling aspect. Most of NEON鈥檚 data is spatially fixed in place, and data from NASA is global, so AOP data fits in between those two. AOP provides a higher resolution data set which takes point measurements and then scales them higher.

What is your role within AOP?

I mostly work with calibrating the spectrometer. I also support fieldwork collected for vicarious calibration of the spectrometer and some fieldwork in support of our Level 1 and Level 2 data. Level 1 data are geo-located and atmospherically corrected while Level 2 data are derived products.

What do like about working at NEON?

Well, I came to NEON when AOP was still a small group so I got to do all of the different things that are part of our AOP mission. I also like getting to work and interact with so many different types of people.

What is something unique about the department?

The cool thing about our data sets is that we have both LiDAR and spectrometer data whereas historic hyperspectral sensors like AVIRIS only collect spectroscopic data.

If AOP were a food, what would it be and why?

(laughs) Lasagna. Because we have many layers.

Final Impressions from Ariel and Maddy

Ariel鈥檚 Final Impressions of AOP: Coming into my internship at NEON, I knew nothing about LiDAR, image processing, or even about the idea of using images taken from planes to study ecological change, so I have really learned a lot hanging out with Maddy and her department. Now I understand that AOP is important to NEON because it provides a completely different type of data. Their data is not spatially fixed like other types of data collected at NEON and can provide a very different insight into ecological change. They also have extensive calibration methods to ensure that the data they collect is valid and useful.

I can now see that AOP is not just flying planes and taking pretty pictures; they provide integral data that can lead to new insights and they complement and extend the data from other departments. Plus, their data is the hardest to process so they give my folks (the CI Team) a challenge!

Ariel鈥檚 Final Impressions of her own department - CI: CI is a unique department at NEON because it isn鈥檛 actually providing its own data, but it is making the data collected from a national observatory available to the scientific community. Without CI, NEON鈥檚 goal of providing long-term ecological data to the scientific community would be impossible. By working with every department to meet NEON鈥檚 goal, CI embodies the age-old saying: 鈥渢he whole is greater than the sum of its parts鈥�.


Maddy鈥檚 Final Impressions of CI: After spending time with Ariel and other members of Cyber Infrastructure, the importance of CI is abundantly clear.  My initial impressions of Ariel鈥檚 role to just 鈥渃ode鈥� things were not entirely wrong, but they were an extreme understatement.  Not only is CI responsible for coding software we employ, they are really the 鈥渇inal portal鈥� through which ALL the collected data runs.  They are the ones making it possible for people to actually make use of what we are collecting.

Another thing I find inspiring is CI鈥檚 modus operandi, so to speak.  I spent a morning with Ariel at what they call a 鈥渟tand-up.鈥� This is a quick, 20-minute meeting they have every morning.  Each week, a different person leads it and directs everyone to explain what they did the previous day, any challenges they faced, and future directions anticipated.  They all stand in front of a board of post鈥搃ts with tasks written on each.  When a project is completed, it is moved to the 鈥渄one鈥� board.  This visual representation of how everyone is working together both ensures no task is being unnecessarily duplicated and allows others to provide assistance when necessary.  This method of collaboration, particularly considering the diversity of programmers, is genius.  For a field pegged as 鈥渁nti-social,鈥� they demonstrate some of the best team work I have ever witnessed. 

Cyber Infrastructure, in my opinion, holds some of NEON鈥檚 greatest unsung heroes.  They are absolutely vital to the NEON Project.

Maddy鈥檚 Final Impressions of her department - AOP: AOP provides a unique data set: it collects both LiDAR and hyperspectral images of all the NEON sites.  Though integral to the overall NEON mission, without the support of other departments (such as CI), it could not be successful.  Working with AOP has taught me innumerable skills in image processing, sensor calibration, and teamwork.  Experiencing Ariel鈥檚 work in CI has complimented everything I鈥檝e learned in AOP by showing me the importance of interdisciplinary collaboration鈥� two heads are better than one!

This is the fourth in a series of Fall blog posts written by our 2014 summer interns reflecting on their experiences at NEON.
