|Description||The Topex Microwave Radiometer (TMR) replacement product, version 1.0, is intended as an interim product for use with the version B Topex MGDRs while a new Topex/Poseidon GDR is being generated. The new GDR will contain the TMR data provided in this replacement product. The TMR replacement product was generated after a recalibration of the TMR for the entire Topex/Poseidon mission by Shannon Brown at JPL.|

Description: The TMR measures the sea surface microwave brightness temperatures at three frequencies (18 GHz, 21 GHz and 37 GHz) to provide the total water-vapor content in the troposphere along the altimeter beam. The 21 GHz channel is the primary channel for water-vapor measurement. It is redundant (21A and 21B). The 18 GHz and 37 GHz channels are used to remove the effects of wind speed and cloud cover, respectively in the water-vapor measurement. TMR data are sent to CNES for processing along with their altimeter data. The measurements are combined to obtain the error in the satellite range measurements caused by pulse delay due to the water vapor.
