ArcticRIMS: Daily Precipitation From Monthly Station Records And Disaggregation

This data set, spanning the period 1980-2008, is assembled from (1) interpolation of observed monthly totals from available station records with bias adjustments (2) disaggregation of the monthly totals to daily totals, making use of daily precipitation forecasts from the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis [Kalnay et al., 1996]. Station records from 1990 onwards are considered to be too sparse to assemble gridded products using this approach.

A daily product from 1980 through the present is described separately (DAILY PRECIPITATION FROM STATISTICAL RECONSTRUCTIONS). This latter product, which is continually updated, makes use of a suite of variables from the NCEP/NCAR reanalysis. The data are presented in 24 sub-datasets of different spatial and temporal aggregations.
