Announcement of the 2019 NASA GLOBE Fall Clouds Challenge

NASA is requesting your help to determine “What’s up in your Sky”. The GLOBE Clouds team wants to study differences in clouds and aerosols. The data collected during this fall challenge will be compared to results from the 2018 Spring Clouds Challenge. Help by submitting clouds, dust, haze or smoke observations (limit of 10 per day) to GLOBE using any of GLOBE’s data entry tools including the clouds tool on the GLOBE Observer mobile app. GLOBE and GLOBE Observer participants submitting the most observations (limit of 10 per day) will be congratulated by NASA scientists with a video posted on the NASA GLOBE Clouds website.
