Over the course of 2019, you helped us collect data, observe an eclipse, GO on a Trail, do research, and make new friends.  >>

To better understand the route’s current land cover conditions, this summer, we asked people to take pictures of the land cover along this area of interest, using the GLOBE Observer App. The GO on a Trail data challenge began June 1 and ended on September 2, 2019. Thus far, participating GLOBE observers have collected and submitted hundreds of observations along the Lewis and Clark route.  >>

ou may have heard the news- there is an exciting challenge this summer for GLOBE Observer users! The challenge follows in the spirit of early cartographers, Meriwether Lewis and William Clark, and you can win one of two ways. First, use GLOBE Observer to map as much land cover as possible in any GLOBE country by September 2. The top data collectors in each GLOBE region will be recognized. Or, for U.S. users, head to the Lewis and Clark National Historic Trail between Pittsburgh, PA and the Oregon Coast, and take Land Cover and Mosquito Habitat Mapper observations using the GLOBE Observer app. This 3 month campaign kicks off on National Trails Day (June1) and concludes on Labor Day (Sept 2). Each observation you make along the trail will increase your chances to be one of our top observers and be eligible for a prize package.

Are you participating in our GO on a Trail Challenge? To join, just use your GLOBE Observer app to take as many land cover observations as you can. You can get points toward winning two ways: collect observations on the Lewis and Clark Trail or collect observations in any GLOBE country.  >>

This year NASA and the National Park Service encourage the public to follow in these explorers’ footsteps through a new citizen science challenge from June 1 to Sept. 2. Use your smart phone and the NASA GLOBE Observer (GO) app to map land cover along the Lewis and Clark National Historic Trail and elsewhere to assist scientists studying environmental changes.  >>
