Abstract :
The Advanced Microwave Scanning Radiometer (AMSR) on board the Advanced Earth Observing Satellite-II (ADEOS-II, or Midori-II) has two channels in the oxygen absorption bands. This is the first attempt to obtain brightness temperatures at the channels by a conically scanning microwave radiometer with high spatial resolution. Potential applications of the channels include the air temperature monitoring, improving geophysical parameter retrieval by incorporating the information of air temperature, and sensing hydrometeor information by utilizing the different penetration depth compared to other window-frequency channels. Since one of the future trends of passive microwave instruments is to integrate the imaging and sounding capabilities into single conical scanning instrument, AMSR data will provide some insights to those future plans. We introduce some potential uses of the channels in conjunction with the preliminary examples of actual AMSR data
