importamsr: Import AMSR binary files

In rcdo: Wrapper of 'CDO' Operators

Import AMSR binary files

Description

This operator imports gridded binary AMSR (Advanced Microwave Scanning Radiometer) data. The binary data files are available from the AMSR ftp site (ftp://ftp.ssmi.com/amsre). Each file consists of twelve (daily) or five (averaged) 0.25 x 0.25 degree grid (1440,720) byte maps. For daily files, six daytime maps in the following order, Time (UTC), Sea Surface Temperature (SST), 10 meter Surface Wind Speed (WSPD), Atmospheric Water Vapor (VAPOR), Cloud Liquid Water (CLOUD), and Rain Rate (RAIN), are followed by six nighttime maps in the same order. Time-Averaged files contain just the geophysical layers in the same order [SST, WSPD, VAPOR, CLOUD, RAIN]. More information to the data is available on the AMSR homepage http://www.remss.com/amsr.

Usage

cdo_import_amsr(ifile, ofile = NULL)

Arguments

ifile	String with the path to the input file.
ofile	String with the path to the output file.
