This dataset introduces monthly and annual climate maps for relevant hydroclimatic variables in Bolivia. We have used the most complete network of precipitation and temperature stations available in Bolivia, which passed a careful quality control and temporal homogenization procedure. Monthly average maps at the spatial resolution of 1-km are modeled by means of a regression-based approach using topographic and geographic variables as predictors, and adding the residuals between observations and predictions, which were interpolated using the inverse distance weighting algorithm. The monthly average maximum and minimum temperatures, precipitation, and topographically modeled exoatmospheric solar radiation are used to estimate the monthly average atmospheric evaporative demand by means of the Hargreaves model. Finally, the average water balance is estimated on a monthly scale for each 1-km cell size by means of the difference between precipitation and atmospheric evaporative demand. Annual maps are created by averaging monthly values for temperature and adding the monthly values for precipitation, atmospheric evaporative demand and water balance. The digital layers are availablein ArcGIS ASCII format.

This contains five zip files with 13 files each one. The format of the files is ArcGis ASCII, which can be imported or directly opened by different files. The five files are: precipitation.zip, contains the monthly (12) and annual (1) ASCII files for precipitation. tmax.zip, contains the monthly (12) and annual (1) ASCII files for maximum temperature. tmin.zip, contains the monthly (12) and annual (1) ASCII files for minimum temperature. ETo.zip, contains the monthly (12) and annual (1) ASCII files for reference evapotranspiration. balance.zip, contains the monthly (12) and annual (1) ASCII files for water balance. Cordinates are geographic (WGS84) The boundaries of the files are: min. X : -69.6646075000000 max. X : -57.5146075000000 min. Y : -22.9054771000000 max. Y : -9.67547710000000 spatial resolution is 0.009 degrees (about 1 km. of spatial resolution).
