Observed precipitation climatology for the Baltic
Abstract
Within the framework of the Baltic Sea Experiment (BALTEX) and the Global Precipitation Climatology Project (GPCP) different precipitation data sets from surface and remote sensing measurements have been compiled. These data sets comprise precipitation analyses from about 6,000 bias-corrected rain gauge measurements in the Baltic (resolution: 0.2 degree/daily) and measurements over the Baltic Sea from ship rain gauges mounted on merchant ships (resolution 1.0 deg/seasonal), both developed during the BALTEX project for the period 1995-2001, as well as fields derived from different global precipitation products. These global products comprise the GPCP-V2, the GPCP-1DD as well as the 0.5-degree product from the GPCC. The GPCP-V2 product is a merged rain gauge satellite product available for the period 1979 to present (2.5 degree/monthly) based on about 6,000 gauges worldwide and various satellites. The GPCP-1DD product is available for the period 1997 to present (1.0 degree/daily) and based on 3-hourly satellite observations only. In opposite, for the analysis of the GPCC product (0.5 degree/monthly) only rain gauges are used. The GPCC database consists of about 40,000 gauges worldwide. We present these data sets for the region of the Baltic Sea drainage basin by comparing them to each other, discussing the special features of the precipitation regimes in the Baltic and pointing out some applications of the data in recent research projects.
