"I use the tree app to look at tree heights and compare them to satellite-derived heights."

Where are you from? 

Malvern, Pennsylvania, USA


What do you do?  

I’m an Earth Scientist that studies ice. Sometimes, I get to go conduct field work in some of the iciest places on Earth, like Alaska, Greenland, and Antarctica. Field work can be quite exciting although sometimes not in the way you were expecting (or prepared). Using satellite data has its own challenges but can be used to show changes over time (almost 50 years from Landsat alone).


How do you use GLOBE Observer?  

I use the tree app to look at tree heights and compare them to satellite-derived heights.


How do you plan to use GLOBE Observer in the future?

I plan to use GLOBE Observer in and around the NASA GSFC campus in Greenbelt MD to assess our aging tree canopy, and monitor any changes from the ground. Since this is where I work, I'm planning to compare the tree height measurements from GLOBE Observer and satellite measurements when they overlap and then be able to measure the trees myself. This way I can verify the accuracy of each method of measurement.


Why is citizen science important to you?  

NASA citizen science is important because it greatly expands the reach of NASA science around the world.


What advice do you have for people just getting into citizen science?  

Ask questions and tune in for webinars and contests.


What do you do for fun? 

I like to canoe, kayak, and bike.


What inspires you? 

I'm inspired by contributing to a greater understanding of the Earth as it changes through time.
