| Description | The enhanced Jason-1 Microwave Radiometer (JMR) corrections contains better wet tropospheric path delay corrections along with better land, rain and ice flagging for coastal regions than that found in the Jason-1 Geophysical Data Records (GDR, http://podaac.jpl.nasa.gov/dataset/JASON-1_L2_OST_GDR_Ver-C_Binary ). The enhanced corrections can be used in place of the GDR wet troposphere correction to provide more accurate Sea Surface Height Anomalies for coastal regions. |

| Platform/Sensor | JASON-1 / Platform Name: JASON-1 (JASON-1) Orbit Period: 112.43 minutes Inclination Angle: 66.04 degrees Ascending Node: 1970-Jan-01 00:00:00 JMR SENSOR Name: JASON-1 MICROWAVE RADIOMETER (JMR) Swath Width: - km Description: The JMR mreasures teh sea surface microwave brightness temperatures at three frequencies (18.7 GHz, 23.8 GHz and 34.0 GHz) to provide the total water vapor content in the troposphere along the altimeter beam. The 23.8 GHz channel is the primary channel for water-vapor measurement and is a redundant channel on the JMR. The 18.7 GHz channel provides a correction for wind-induced effects in the sea surface background emissions, and the 34.0 GHz channel provides a correction for cloud liquid water. The measurements are combined to obtain the error in the satellite range measurements caused by pulse delay due to the water vapor. |
