ADVANCED MICROWAVE SOUNDING UNIT-A (AMSU-A) SWATH FROM NOAA-17

AMSU-A, the Advanced Microwave Sounding Unit, is a 15-channel passive microwave radiometer used to profile atmospheric temperature and moisture from the earth's surface to ~45 km (3 millibars). All orbits beginning in the day (00:00:00 - 23:59:59 UTC) are stored in one daily HDF-EOS file. Each file contains 15 (channel) arrays, as well as corresponding latitude, longitude, and time. AMSU flies on the National Oceanic and Atmospheric Administration (NOAA) polar orbiting spacecraft as part of the National Polar-orbiting Operational Environmental Satellite System (NPOESS). The Third Advanced Microwave Sounding Unit-A was launched on NOAA-17 on 24 June 2002 from Vandenberg AFB, California on a Titan II booster.

AMSU-A，即高级微波 sounding 单元，是一款15通道的被动微波辐射计，用于从地球表面至约45公里（3毫巴）的高度对大气温度和湿度进行剖面观测。所有自日间（00:00:00 - 23:59:59 UTC）开始的轨道数据均存储在一个每日的 HDF-EOS 文件中。每个文件包含15个（通道）数组，以及相应的纬度、经度和时间信息。AMSU 搭载于美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，简称NOAA）的极地轨道航天器上，作为国家极地轨道业务环境卫星系统（National Polar-orbiting Operational Environmental Satellite System，简称NPOESS）的一部分。第三代高级微波 sounding 单元-A于2002年6月24日从加利福尼亚州范登堡空军基地（Vandenberg AFB）搭载NOAA-17卫星，由泰坦II号火箭助推器发射升空。
