SINGLE-SOURCE DATASETS

Table 3. Summary of publicly available, quasi-operational, quasi-global precipitation estimates from a single satellite sensor type. Where appropriate, the algorithms applied to the individual input data sets are mentioned. The GPROF TMI and PR are available as separate products from the Goddard DISC, in addition to the 3G68 compilation. Solid shading indicates products that are not yet available.
