MARINE WEATHER SYSTEMS: STUDY WITH ASEOS-II AMSR, AQUA AMSR-E AND ENVISAT ASAR

Observations carried out by the Aqua AMSR-E (Advanced Microwave Scanning Radiometer), ADEOS-II AMSR and Envisat ASAR (Advanced Synthetic Aperture Radar) have been used to study the distribution of total water vapor content V, total cloud liquid water content Q, precipitation R and surface wind W in...
