The Microwave Humidity Sounder (MHS) is an instrument launched on NOAA's POES satellite series starting with NOAA-18 launched in May 2005 and European Space Agency's MetOp series starting with MetOp-A launched in October 2006 and continuing with MetOp-B launched in September 2012. It is a five-channel passive microwave radiometer, with channels from 89 to 190 GHz. It is very similar in design to the AMSU-B instrument, but some channel frequencies have been altered. It is used to study profiles of atmospheric water vapor and provide improved input data to the cloud-clearing algorithms in IR/MW sounder suites. The Microwave Humidity Sounder has been designed and developed by Astrium EU in Portsmouth UK, under contract to EUMETSAT. == Instrument Characteristics == *Heritage: AMSU-B, HSB *Swath: 1650 km *Spatial resolution: 17 km horizontal at nadir *Mass: 63 kg *Duty cycle: 100% *Power: 74 W (BOL) *Data rate: 4.2 kbit/s *Field of View: ± 49.5 degrees cross-track *Instrument Instantaneous Field of View: 1.1 degrees circular Table 1: Radiometric characteristics of the MHS 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Microwave humidity sounder」の詳細全文を読む スポンサード リンク
