(MI_Instrument) uuid: 8293FAD4B8DA75F2E040AC8C5AB4576F identifier: (MD_Identifier) code: AMR > Advanced Microwave Radiometer type: radiometer description: Instrument Type: radiometer, Operational Mode: , Collection Type: microwave, Other Information: AMR acquires measurements via three separate frequency channels to determine the path delay of the altimeter's radar caused by atmospheric water vapor. This instrument measures radiation from Earth's surface at three frequencies (18, 21 and 37 GHz). Measurements acquired at each frequency are combined to determine atmospheric water vapor and liquid water content. Once the water content is known, we can determine the correction to be applied for radar signal path delays. |
