ABSTRACT Computer modelling the map of average annual temperature in the ground layer of air is performed for the southern part of Western Siberia (Russia). Four methods for data interpolation were used in ArcMap 9. Procedure of creation of digital model is described in detail. An original mathematic way for ranking of methods is proposed. According to results, Ordinary Kriging method gives the best approximation to the initial data. ...

ABSTRACT CO is one of the main air pollutant which leads to many problems for human. Mega cities such as Tehran have critical issues by increasing the vehicles, fuel usage and urban area expansion. Hence, to have a clear view points on the pattern of CO concentration in Tehran, the data of 14 air quality concentration centers in a midterm period (2009 and 2012) are used. The main novelty of this research is usi...
