Development and evaluation procedure for the gridded climate database on China
This gridded database of mean monthly climatic data was developed by IIASA's LUC project in collaboration with the Potsdam Institute for Climate Impact Research (PIK). It has a grid-cell size of 5 km for monthly mean precipitation and temperature and minimum and maximum temperature for the region of the Former Soviet Union, Mongolia and China. IIASA's LUC project provided W.Cramer at PIK with the longitude, latitude and altitude information of each 5 km grid cell and he performed the interpolation procedure for the climatic data, using a methodology described in Leemans and Cramer, 1991.
For China the yearly precipitation map had inaccuracies in the difficult terrain of south-western China on the Tibetan plateau where only few station data are available. Therefore, in this area apparent inaccuracies in yearly precipitation were manually corrected in a GIS environment, using hardcopy atlases from a Chinese source (see: Institute of Soil Science, 1986). The annual changes were translated into the monthly rainfall data applying the same ratio of yearly distribution as the original data.
