This paper presents a method of generating a meteorological database using GIS technology designed for detailed description of thermophysical characteristics of the underlying urban surface. Geoprocessing models and custom tools were developed using Esri ArcGIS Desktop 10 for calculation of height statistic (average, standard deviation and geometric mean), sky view factor and H/W ratio, predominant street direction, percentage ratio between impervious, pervious surface and built-up area within each cell of regular grid covering the study site. These tools were applied to derive detailed database of urban land thermophysical characteristics for Moscow city. The resulting system of tools allows creating similar databases for any city within any country and climates.
