EOS MLS Algorithm Theoretical Basis for Cloud Measurements

MLS has unique ability to make global observations of cloud ice in the upper troposphere. As part of NASA “A-Train” concept, the MLS measurements will be in line with Aqua (since 2002) and CloudSat 94-GHz Cloud Profiling Radar (CPR) (due for launch in 2005) measurements with the footprints only 7 min apart. The synergy of radar-radiometer observations is expected to offer a unique opportunity for accurate measurements of ice water content and effective particle size in the upper troposphere.
