Associated Platforms OSTM/JASON-2 Spectral/Frequency Information Wavelength Keyword: Microwave Spectral/Frequency Coverage/Range: 18.7, 23.8, and 34 GHz Related Data Sets View all records related to this instrument Description The Advanced Microwave Radiometer (AMR), is an enhanced version of the Jason-1 Microwave Radiometer (JMR). Like the JMR, it 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. Additional information on the AMR is available on the AVISO site.
