DESCRIPTION:The question “How can Mongolia\, which has a huge amount of r
 enewable energy resources\, develop “green” sources of energy in accor
 dance with the specifics of its’ climate and energy consumption?” has 
 become a pressing issue in the energy sector. There is an urgent need to t
 ake comprehensive measures to reduce air pollution in Ulaanbaatar\, where 
 half of the country's population lives and which has a coal-dependent ener
 gy supply. Within this\, the research to create sustainable and environmen
 tally friendly renewable energy has become a priority.\nAbout 48 percent o
 f air pollution in Ulaanbaatar comes from households in ger districts. To 
 reduce this amount\, the need to use solar energy for their heating is req
 uired\, so it is practical to estimate the potential amount of solar energ
 y based on digital surface models. \nIn this study\, we used Geographic In
 formation System (GIS) to calculate the potential amount of solar energy r
 esources in 6 districts of central Ulaanbaatar using a digital elevation m
 odel (DEM). The DEM was calculated from a topographic map with a scale of 
 1: 25000. In addition\, objects such as buildings and trees were added to 
 the Ulaanbaatar city database\, and a numerical surface model was develope
 d digital surface model (DSM) and used for further processing. The results
  were compared with the results of previous research. The results of this 
 work are in line with previous estimates from meteorological data surveys.
  In the latitudes of Ulaanbaatar\, the sunshine lasts 2\,800 hours a year\
 , which is relatively longer than in the highlands. The sun shines 145-170
  hours in winter\, 276-300 hours in spring for 3-4 months\, 290-300 hours 
 in summer\, and 225-250 hours a month in autumn and summer.\nAccording to 
 the study\, the potential amount of solar energy resources was calculated 
 on a total area of 206\,705 hectares\, and the maximum area that could sto
 re 1\,200-1\,500 kWh / m 2 of energy per year was 47\,313 hectares. Exclud
 ing areas where it is not possible to build renewable energy facilities\, 
 such as sanitary restrictions\, forests\, cemeteries\, farmland\, special 
 needs areas\, reservoirs\, waste disposal sites\, and airport protection z
 ones\, 1100-1500 kWh per year. * 17\,000 ha of potential energy storage ar
 ea is within the boundaries of the construction restriction. This research
  is an unprecedented work in our country\, as it calculates the potential 
 amount of solar energy resources using a digital model of the surface. In 
 addition\, it provides an opportunity to use renewable energy for future p
 lanning and research.\nIn the policy of Mongolian green development main t
 arget is to reduce greenhouse gas and supporting to new friendly-environme
 nt energy sources. According to this policy\, renewable energy will reach 
 30% in 2030 including all energy industries. This research has estimated s
 olar radiation in Ulaanbaatar city using the Digital Elevation Model (DEM)
 \, Digital Surface Model (DSM)\, and building height information
