Quick look and ground Truth Precipitation Atlas for analyzing weather pattern and validating numerical simulations with completely independent background information for the period Aug. 95 to Oct. 95

Summary:
The quick look atlas is based upon the data of routine SYNOP stations. It gives an account of the spatial precipitation fields during each day of the period Aug. 95 to Oct. 95. The ground truth atlas is based on an order of magnitude more stations (more than 4000 locations of daily precipitation observations within the catchment of the Baltic Sea), plus a quality check and corrections of measurements. The analysis was done using Ordinary Block Kriging. The main part of the atlas shows 92 precipitation fields within the Baltic Sea drainage basin. For each precipitation field an error field was calculated.

Further the atlas contains a couple of comparisons with earlier analyses as well as predictions from models (HIRLAM, REMO), demonstrating possibilities and limitations with using the precipitation atlas in model validation.
