The weather monitoring module is one of the main elements of the MCYFS. It is divided in three categories:
The data bases store the input data and output data. The data fluxes represent the flow of data from external sources to the data bases, between data bases, towards others parts of the system and to end-users (clients). The procedures manipulate the data.
Quality check of station weather by AMDAC Interpolating station weather to 25x25 observed grid weather Downscalling global modeled weather to 25x25 modeled grid weather Aggregate grid weather to regions
Goals and assumptions
Daily meteorological station data are used in two ways for crop yield evaluations. In the first place as input for the crop growth model WOFOST to simulate crops behaviors and evaluate the effects of weather on crops yields at European level (see Crop Simulation). Secondly as weather indicators for a direct evaluation of alarming situations such as drought, extreme rainfall during sowing, flowering or harvest etc.
The crops behaviors are mainly influenced by the atmospheric conditions near the earth surface. Considering the data availability, resources and purpose of the system a time scale of one day and a spatial scale of 25 by 25 km are chosen as the resolutions to estimate crop yields at European scale.
