The Agroclimate Model gives information on important - from the point of agriculture - weather phenomena and can be used in planning the development of agricultural production. Essential building blocks of the Model are algorithms for calculating climatic parameters (e.g. temperature of the air) in points of known geographic location. The algorithms make possible the determination of statistical distribution of the most important climatic parameters in any given place in Poland and in any given period - parameters such as temperature, precipitation, relative humidity, sunshine duration, evapotranspiration, agricultural periods, climate valuation with regard to various crops, conditions of cultivation of thermophilous plants and yield variability.
The algorithms link the yearly cycle of meteorological elements (determined with the aid of harmonic analysis) with their spatial image (as a function of geographic co-ordinates). They make possible to present fully mean values of climate parameters (along with their variability) in four-dimensional space, one dimension of which being time. Integration of the algorithms with a spatial database (digital model of terrain - DTM) made possible to create a mathematical model of agroclimate. With the aid of the Model not only point information may be accessed easily, but also numerical map creation of agroclimate parameters in arbitrary time cross-sections can be automated to a great extent. Moreover, the resultant impact of selected weather factors can be assessed.
It is quite easy to operate the Model. The user, after a point has been selected from the map of Poland, can change its height above sea level and input the period (selection from the calendar displayed upon pressing the icon
), for which the calculation is to be conducted. After the button
has been pressed, calculation procedures placed on the server will be started and the results sent to the user's browser.
It is quite easy to add other information such as soil or economic one to climatic information of the Model. This provides an array of possibilities, for instance regions most suitable for crop cultivation can be easily determined (e.g. vis. DSS for hop replanting
