Chang SSM/I Derived Monthly Rain Indices 5 x 5 degree V2.3 (RAIN_CHANG) at GES DISC

Version 2.3
  • Abstract
    The SSM/I Derived Oceanic Monthly Rainfall Indices data set is a GlobalbPrecipitaton Climate Project (GPCP) product. Monthly rainfall indices overnthe oceans are derived from Special Sensor Microwave Imager (SSM/I) data from the Defense Meteorological Satellite Program (DMSP) satellites F8 and F11 on channels 19 and 22 V. The data set covers the period from July 1987 to December 1995. The monthly rainfall indices are on a 5 degree by 5 degree grid extending from 50 N to 50 S. The Wilheit, Chang and Chiu (1991) method used to derive the indices gives valid values only over ocean areas. Land pixels (including island pixels) and erroneous pixels return a -10 flag. The data are stored on a 72 x 20 grid. Grid point (1,1) contains the index for 45-50 N, 0-5 E, grid point (2,1) contains the index for 45-50 N, 5-10 E, ... and grid point (72,20) contains the index for 45-50 S, 175-180 W. In the data set, each month starts with an ASCII header to identify the year and month. The data is in 10F8.1 format. Each value is the average of AM and PM estimates and corrected for beam filling error. The equation used is: (AM PM)/2.0 * 1.8. Land pixels are set to -10.0. Also there are 33 pixels blocked out due to island contamination (-10.0). If the rain retrieval did not converge, a -10.0 is assigned to the pixel. The objective of this data set is to provide a long term monthly rainfall data set to be used in EOS global change and GEWEX related research. The data set can be accessed through the IMS. Data maintained in an off-line archive will also be listed in the IMS, and orders will be filled as the data is requested. The SSM/I Derived Oceanic Monthly Rainfall Indices data set will be reviewed every six months to ensure that the most current version of the data is available.
