The Global Snowflake Network (GSN) is a NASA-funded program that involved the general public in collecting and 'classifying' falling snowflakes. The data are being compiled into a global database, along with satellite images, to help climatologists and others who study climate-related phenomena gain a better understanding of winter meteorology as they track various snowstorms around the globe. The project also provided thermochrons to classrooms to help students carry out winter research. The website includes videos and written information about the snowflake protocol, as well as downloadable data sheets.
