Introduction

The weather monitoring module is one of the main elements of the MCYFS. It is divided in three categories:

  • data bases
  • data fluxes
  • procedures

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.

General description

The weather monitoring module contains 4 procedures that manipulate the data.

  • Every day the incoming station weather of roughly 3000 european weather stations is qality checked by AMDAC software.
  • Every day the checked station weather is interpolating to a 25x25km grid completely covering the european region.
  • Every day forecast weather from ECMWF is downscaled to the same 25x25km grid.
  • Every day all grid weather is aggregated to regions.

Interpolation to 25x25km grid

The interpolation is managed by a sub-system called Crop Growth Monitoring System (CGMS). For each grid cell every day the most suitable stations are selected and used to interpolate a grid value. From day to day and from weather indicator to weather indicator different stations can be used.


All input data and output data of CGMS is stored in a relational database of which the structure is presented in Appendix 4. Individual tables are described in Appendix 5. Procedures may be stored as database objects, scripts or separate software packages. A detailed description of the software procedures can be found in Appendix 3.

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.
