Drought Time Series Based on the Standardized Precipitation Index for Guam from 1954 to 2022 and Koror from 1952 to 2019

This dataset contains an input of calculated average monthly rainfall values for Guam and drought time series data that covers two islands. The Guam drought time series is based on the standardized precipitation index (SPI) three-month intervals (SPI-3) and twelve-month intervals (SPI-12). Calculated from monthly rainfall values from 1954 through 2020 were produced for the whole land area of Guam from gridded monthly rainfall maps, which were developed using historical daily rainfall data and climatologically aided interpolation (CAI) methods similar to those described in Longman et al. (2019). The Koror drought time series is based on the standardized precipitation index (SPI) three-month intervals (SPI-3) and twelve-month intervals (SPI-12). Daily rainfall values from 1952 through 2019 collected at the Palau Weather Service Office in Koror.
