New global precipitation products and data service updates at the NASA GES DISC

Built upon the success of the NASA/JAXA Tropical Rainfall Measuring Mission (TRMM), the Global Precipitation Measurement (GPM) mission advances light rain and snow measurements as well as our understanding of the global water cycle, storm structure, precipitation microphysics and climate change. The NASA Goddard Earth Sciences (GES) Data and Information Services Center (DISC) hosts and distributes both TRMM and GPM products with data services to facilitate data access and scientific discovery. In this presentation, we will introduce the latest Version-4 GPM products including the IMERG and value-added daily products developed at the GES DISC along with GPM version-3 and 4 comparison samples. The newly arrived the version-3 Global Precipitation Climatology Project (GPCP) product, supported by the NASA MEaSUREs (Making Earth System Data Records for Use in Research Environments) program, provides a climate data record for global precipitation from 1979 to present. Enhancements have been made such as the spatial resolution that has been improved from 2.5-deg. to 0.25-deg. We will present information on data access and examples of GPCP 3. We will present the latest features and updates from the popular online visualization and analysis tool, GIOVANNI (http://giovanni.gsfc.nasa.gov/). Precipitation products from other NASA projects such as MERRA, NLDAS and GLDAS will be presented as well.
