- Аннотация: This paper presents a universal method of generating the meteorological data‐ base using GIS technology designed for detailed description of the thermo‐ physical characteristics of the underlying urban surface. Some of the characteris‐ tics that are most appropriate for this aim have been selected, according to two principles: universal applicability and frequency of use in studies around the world. The chosen set of characteristics includes: sky view; H/W ratio; built sur‐ face fraction; albedo; thermal; anthropogenic heat flux; expectation function, standard deviation and average of height. It is proposed to carry out the calcula‐ tion of these characteristics within each cell of regular grid covering the study site. It allows easily assimilate data by any atmospheric boundary layer model, also change the size of grid cell. In other words, universality of the calculation method will be ensured. Our study area for testing universal method of generat‐ ing the meteorological database is Moscow, Russian Federation. GIS extension is created for calculating all thermo‐physical characteristics based on ESRI product – ArcGis 10. GIS technology is used in order to ensure flexibility and efficiency method. Nevertheless, the two values of characteristics set (thermal admittance and anthropogenic heat flux) are currently difficult to assess even within well‐ studied cities in developed countries. In Russia these estimates have not been carried out yet. In order to solve this problem, study area has been zoned using newly created classification by Stewart and Oke. (Stewart I.D., Oke T.R., 2010) Also the applicability of the local climate zone classification for East‐European type of building has been assessed. 1.
