GPCP Precipitation Level 3 Daily 0.5-Degree V3.3 (GPCPDAY)

Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/measures/gpcp/data307

Version 3.3 is the current version.

Description

Older versions have been superseded by Version 3.3. Product latency/update: The products are currently paused at September 2024 because the IR input dataset from NCEI requires a new calibration scheme to extend past that point.

Once NCEI irons out the calibration, we expect to return to quarterly updates. The Global Precipitation Climatology Project (GPCP) is the precipitation component of an internationally coordinated set of (mainly) satellite-based global products dealing with the Earth's water and energy cycles, under the auspices of the Global Water and Energy Exchange (GEWEX) Data and Assessment Panel (GDAP) of the World Climate Research Program.

As the follow on to the GPCP Version 1.3 One Degree Daily product, GPCP Version 3 (GPCP V3.3) seeks to continue the long, homogeneous precipitation record using modern merging techniques and input data sets. The GPCPV3 suite currently consists of the 0.5-degree Monthly and 0.5-degree Daily. Additional products may be added, which consist of (1) 0.5-degree pentad and (2) 0.1-degree 3-hourly.

All GPCPV3 products will be internally consistent. Inputs consist of GPM IMERG in the span 55°N-S, and TOVS/AIRS estimates, adjusted climatologically to IMERG, outside 55°N-S. The Daily estimates are scaled to approximately sum to the Monthly value at each 0.5° grid box. In addition to the final precipitation field, probability of liquid phase estimates are provided globally.
