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). 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.

DATA CITATION GUIDELINES

Variables

Variables are a set of physical properties whose values determine the characteristics or behavior of something. For example, temperature and pressure are variables of the atmosphere. Parameters and variables can be used interchangeably. Variable level attributes provide individual information for each variable.

The Name in this table is the variable name. Fill value indicates missing or undefined data points in a variable. Valid range is the range of values the variable can store. Scale factor is used to increase or decrease the size of an object and can be used to correct for distortion. For questions on a specific variable, please use the Earthdata Forum.

Name Description Units Data Type Fill Value Valid Range Scale Factor

lon Longitude [0:360] degrees_east int N/A N/A 1.0E-6
rad_epd_land_flag JMR Enhanced Wet Tropo Path Delay Land Flag (0=no land, 1=costal processing applied, 2=land); Enhanced PD land flag is 2 when radiometer enhanced wet path delay product is invalid due to land contamination contamination / byte 127 N/A 1
rad_rain_flag JMR Rain Flag (0=no rain, 1=rain); Rain flag is 1 when GDR wet path delay or enhanced wet path delay radiometer product is invalid due to rain contamination / byte 127 N/A 1
rad_sea_ice_flag JMR Sea Ice Flag (0=no ice, 1=ice); Ice flag is 1 when GDR wet path delay or enhanced wet path delay radiometer product is invalid due to sea ice contamination / byte 127 N/A 1
