With a focus on establishing consistency, GDAP oversees a number of assessments of key parameters related to Earth’s energy and water cycles as well as the development of a GEWEX Integrated Product that incorporates several previously supported energy and water flux datasets into a long-term product on a common grid for energy and water cycle closure studies GDAP also sponsors ground-based observing networks that provide high-quality, calibrated, observations for evaluating satellite data sets.
Narrative on integrated product (Kummerow). This is the only global/satellite data product currently supported by GDAP.

The International Soil Moisture Network is an international cooperation to establish and maintain a global in-situ soil moisture database. This database is an essential means for validating and improving global satellite products, and land surface, climate, and hydrological models.
The Global Precipitation Climatology Centre (GPCC) provides global precipitation analyses for monitoring and research of the earth’s climate.
GDAP is also coordinating the formation of a new international effort to advance the next-generation International Satellite Cloud Climatology Project (ISCCP). The goal of the ISCCP-NG effort will be to maintain continuity of the ISCCP while developing new global cloud products that exploit the increased spatial and temporal resolution, spectral diversity, and improved calibration afforded by advanced geostationary imagers to support new research and applications.
