The aim of the study was a comparison of selected meteorological elements, measured with automatic weather stations in two localizations: centre of an urban area (Bydgoszcz) and in an open surroundings (Mochełek). The distance between the both places was about 20 km in a line. Results of the investigation confirmed the presence of a heat urban island in Bydgoszcz. The urban area was distinguished by higher (of 1.3°C) air temperature higher saturation deficit (1.1 hPa), whereas lower mean monthly relative humidity (8.3%), wind speed (2.5 m•s-2), monthly total precipitation (7.8 mm) and global solar radiation (32%), comparing to the rural location. The distinctions were not equal in particular monthly periods and in particular cases of meteorological elements. Global solar radiation, air temperature, relative humidity and wind speed differ most in the winter time while saturation deficit and precipitation vary in summer.

The aim of the study was comparison of chosen meteorological elements (air temperature, precipitation and global solar radiation) measured in the warm half-a-year with classic and automatic weather stations. Basing on the measurements three agrometeorological indexes (climatological water balance, evapotranspiration and standardized precipitation index) were calculated. With the obtained results, prospects of automatic data use for meteorological cover in agriculture was evaluated along to the homogenious series maintaining. A particular consideration of correlative results was done to assign mathematical formulas that would allowed to use classic and automatic data series exchangeably.
