SHIS 070725

SHIS had another successful flight today with pre-flight and Engineering figures posted on the SHIS web site. Only the ER2 flew today with DC8 grounded due to a lightning strike on the flight on Tuesday. The goal of this flight was a CALIPSO/CloudSat comparison with the ER2. Due to thunderstorms in near San Jose the flight returned early, missing the CALIPSO/CloudSat overpass. The ER2 pilot reported a very thin cirrus layer, about 1 km thick, at 46,000 feet (~14 km). The Cloud Physics Lidar (CPL) worked well. This will be a good case to run S-HIS cloud retrievals on thin cirrus. Unfortunately the cloud radar failed at the begining of the flight so no radar data is available.
