The GLOBE Program (NASA PACE mission)
Deadline shown is curated from the official program page. Programs occasionally shift dates between cycles — confirm the current deadline on the official site before you finalize your application.
Participants photograph cloud cover through the GLOBE Observer app, ideally within five minutes of the PACE satellite passing overhead. NASA scientists compare these ground observations against satellite measurements of cloud edges and total cover. Contributors who submit a complete matched set receive a certificate of recognition.
