CONTENTS

Precipitations products from the available dual-frequency altimeters. Three different data sets are available: the raw altimeter data samples (by quarter), the mean rain rate fields and the mean rain cell lenght fields. Mean rain rate fields are provided as monthly, 3-monthly and annual averages; rain cell lenghts are available for 3-monthly and annual averages. The individual rain samples are also available as netCDF files (samples directory on ftp).
