Observation of a Lunar Eclipse at 89, 150, and 183 GHz

Abstract We describe the measurement of brightness temperature Moon from space during a total lunar eclipse by using microwave sounder aboard weather satellite. Previous observations eclipses were inconsistent and did not cover frequency range between 100 200 GHz. In this work, we seek to establish reliable relationship drop in for millimeter wavelengths. For purpose, chose on 2004 October 28, because it coincided with appearances deep view Advanced Microwave Sounding Unit-B NOAA-15. It was therefore possible measure its disk-integrated radiance at 89, 150, 183 GHz minutes intervals. Our are, best our knowledge, only ones GHz, demonstrate nearly linear dependency maximum relative effective an eclipse. The slope function is m = 0.00114 ± 0.00017 −1 88–300 good agreement variations new radiative-transfer model suggests that suitable as flux standard beam sizes larger than 0.5°.
