Science to help the planet
How much snow is on the ground where you are? Cryosphere researchers want to know! Report the depth of your snow. All you need is a ruler. Please make a report even if you don't have any snow; just report a depth of 0! Your data will show up in our world map of snow tweets!
This project is part of the Changing Planet series in collaboration with the National Science Foundation, NBC News, Discover Magazine, Planet Forward and Science for Citizens.
