Pacific Islands Interpolated Monthly Rainfall from PACRAIN

The Comprehensive Pacific Rainfall Data Base (PACRAIN) was developed under a research grant from the National Oceanic and Atmospheric Administration (NOAA)'s Office of Global Programs (OGP). The PACRAIN project has been supplemented by an extensive collection of rainfall data from schools across the Pacific in the Schools of the Pacific Rainfall Climate Experiment (SPaRCE). Each participating school is sent a rain gauge, instructional manuals and videotapes, and data sheets. Students at the schools record daily rainfall measurements and return the forms to the University of Oklahoma, where they are entered as a part of the PACRAIN database. Additional data analysis and quality-assurance technique development are provided by the Environmental Verification and Analysis Center (EVAC), located at the University of Oklahoma.

This Experimental NetCDF 0.25-degree sea level monthly rainfall estimates for the period January 1941 through Apr 2017. These estimates are derived entirely from 'atoll' station rains to avoid orographically-induced variability. Data prior to 1941 are too sparse to meet interpolation criteria.
