Editor’s Corner

Michael King, EOS Senior Project Scientist

I am pleased to report that, after executing a series of extremely precise maneuvers, both the CloudSat and Cloud Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) satellites are in position in the Afternoon “A-Train” Constellation and formation flying has begun. CloudSat and CALIPSO now join Aqua, Aura, and PARASOL in the A-Train, and these missions will work together to provide new insights into the global distribution and evolution of clouds and aerosols to improve weather forecasting and climate prediction. CloudSat flies about a minute behind Aqua in the formation, and precedes CALIPSO by a mere 12.5 (+/- 2.5) seconds.

Even before the two satellites were in place in the A-Train, the first images from each mission were flowing back to Earth, revealing never-before-seen three-dimensional details about clouds and aerosols. Mission managers tested the flight- and ground-system performance of CloudSat’s Cloud-Profiling Radar (CPR) in late May, and found it to be working perfectly. Thirty seconds after the radar was activated for the first time, the CPR obtained...
