The Legates Surface and Ship Observation of Precipitation data set consists of a global climatology of monthly mean precipitation values, using traditional land-based gauge measurements and shipboard estimates spanning the period from 1920 to 1980. The data are corrected for gauge-induced systematic errors caused by wind, wetting on the interior walls of the gauge and evaporation from the gauge. The corrected monthly precipitation values are then interpolated to a 0.5 degree latitude by 0.5 degree longitude grid using a spherically based interpolation procedure (Legates and Willmott, 1990). This global precipitation climatology is used in 1) verification of climate model predictions of precipitation cycles 2) large scale hydrological cycle and ecological studies 3) evaluating climate change
