The South China Sea Monsoon Experiment (SCSMEX) is a large-scale experiment to study the water and energy cycles of the Asian monsoon regions. The goal is to provide a better understanding of the key physical processes for the onset, maintenance and variability of the Southeast Asian monsoon.

To support the Campaign phase of SCSMEX (May 1 to August 31, 1998), the Seasonal-Interannual Earth Science Information Partner (SIESIP), a joint cooperation between CEOSR/GMU, COLA and GES DISC, is providing the following TRMM data subsets and ancillary data over this period in the SCSMEX region (10S-30N, 95-130E) for analysis.
