-China, Russia, and India increased %
-Stable increases and a few minor decreases for the other countries with the most users.
-Large increases in non native English speaking countries. Challenges for documentation, user support, data requests, etc.
-Interesting to see if language barrier is preventative in any way for people to obtain data

-Decline since 2013, possibly due to the 2012 sea ice low and warm temperatures.
-2016 sure to ramp us when the low is announced, especially if it’s close to 2012.

We welcome all feedback! Please feel free to let us know what you want to see.
Brian, Paul Lisa or USO and let us know what you want to know.
You don’t have to wait for this meeting.
Amanda, Daniel Crumly (Data Operations), and Lisa are participating in an ESDIS discussion group with other DAACs regarding metrics needs and reporting tools.
