NASA observes Earth's clouds on a daily basis and began doing so in 1960. It happens that this week marks the anniversary of the launch of the first satellite sent to observe clouds from space. This and more in this week's roundup.  1. IMAGE OF THE WEEK:  This astronaut photograph taken five years ago ( 25 March 2012)  illustrates the formation of wave clouds in the wake, or downwind side, of Île aux Cochons (“Pig Island”) in the southern Indian Ocean. "The summit elevation is high enough for the land surface to interact with cloud layers and with winds...

Can you guess what island is in the above picture? Find out and learn more in the link below. The Image 2. THEORY...

The Global Learning and Observations to Benefit the Environment (GLOBE) program has released an update to the GLOBE Observer App for iOS and Android. It allows users to provide new data points on sky color, visibility, cloud properties and opacity, and surface conditions. Credits: NASA/David C. Bowman Jessica Taylor, center, team lead for education outreach at NASA Langley's Science Directorate, shows educators how to make cloud observations with the GLOBE Observer app during a recent workshop.

Cloud fraction, a broadcast and spring forward -- this and more in this week's roundup. 1. IMAGE OF THE WEEK:  The image above is from the MODIS instrument on board the Aqua satellite and  shows all of the clouds seen during the month of February (2017). You can access daily and monthly imagery of the Earth and its clouds in the link below. Why not try comparing "Cloud Fraction" across the months to see which was the cloudiest.
