[1] We investigate microwave radiation from the ocean surface to observe changes in microwave radiation for various air-sea temperature differences by using data of the Special Sensor Microwave/Imager 19 GHz and the TRMM Microwave Imager 19 and 10 GHz. To this end, we developed a method of removing the atmospheric effect. Under strong winds exceeding 7m/s, atmospheric-effect-removed temperatures of both vertical and horizontal polarizations increase, and the ratio of the V/H increase in stable condition is less than that in neutral or unstable conditions. Furthermore, in neutral or unstable conditions, the ratio of the V/H increasing at 10GHz is larger than that at 19GHz.
