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. Gray shading indicates products that are not yet available. Yellow shading indicates entries that have not been updated recently. [Last updated 13 July 2022, G.J. Huffman]
