内容記述 | Data collected with the Advanced Microwave Moisture Sounder (AMMS), which operates in the 183.3 GHz range, are compared to measurements collected at 22 GHz in order to show that the 183 GHz measurements are more sensitive to total precipitable water (W) values than the 22 GHz measurements. Radiative transfer calculations for the upwelling microwave emission from the ocean surface were performed at the AMMS frequencies with a variety of atmospheric temperature and humidity profiles. The derived brightness temperatures at these frequencies are compared with W values derived from the humidity profiles. It is observed that the sensitivity between the brightness temperatures and W values at the AMMS channel is greater than 130 K/g per sq cm and 12 K/g per sq cm for the 22 GHz frequency. |
