NOAA Climate Data Record (CDR) of CPC Morphing Technique (CMORPH) High Resolution Global Precipitation Estimates, Version 1
Listed in NASA Earthdata CMR
This data set is for the bias-corrected, reprocessed CPC Morphing technique (CMORPH) high-resolution global satellite precipitation estimates.
Description
The CMORPH satellite precipitation estimates are created in two steps. First, the purely satellite-based global fields of precipitation are constructed through integrating Level 2 retrievals of instantaneous precipitation rates from all available passive microwave (PMW_ measurements aboard low earth orbiting platforms.
Bias in these integrated satellite precipitation estimates is then removed through comparison against CPC daily gauge analysis over land and adjustment against the Global Precipitation Climatology Project (GPCP) merged analysis of pentad precipitation over ocean. The bias corrected CMORPH satellite precipitation estimates are created on an 8kmx8km grid over the global domain from 60deg S to 60deg N and in a 30-minute interval from January 1, 1998.

Due to the delay of some input data sets, this formal version (Version 1) bias corrected CMORPH is produced manually once a month at a latency of 3-4 months. For the CDR production, the bias corrected CMORPH generated at its native resolution of 8kmx8km / 30-minute is upscaled to form THREE sets of data files of different time/space resolution for improved user experience: a) the full-resolution CMORPH data Output variable: precipitation rate in mm/hour spatial resolution: 8kmx8km (at equator) spatial coverage: global (60S-60N) temporal resolution: 30min data period: January 1, 1998 to the present b) Hourly CMORPH Output variable: precipitation rate in mm/hour spatial resolution: 0.25deg lat/lon spatial coverage: global (60S-60N) temporal resolution: hourly data period: January 1, 1998 to the present c) Daily CMORPH Output variable: daily precipitation in mm/day Printed 2015-06-08 - Verify Document Currency Before Use 1 spatial resolution: 0.25deg lat/lon spatial coverage: global (60S-60N) temporal resolution: hourly data period: January 1, 1998 to the present (b) and (c) are derived from and quantitatively consistent with the CMORPH at its original resolution (a).
