To mark the 12th anniversary of the first student cloud observation report for the Students Cloud Observations On-Line (S'COOL) Project, join us January 13, 2009 for a global cloud observation day.

Everyone is invited to make and report cloud observations on this day at the time that the CERES satellite instruments pass over their location.

You can find out "When to Observe" and "What to Observe" at the S'COOL Rover Web site: http://asd-www.larc.nasa.gov/SCOOL/Rover/

Use the "Report Form" to record your observation and send the information to NASA.

About a week later, return to the Web site and explore the "Database" to compare what you and others saw to what the satellite reported.
