Outline of an operational crop state monitoring system
The Agriculture project of the Institute for Remote Sensing Applications at the JRC is undertaking a project to develop a system for the production of maps depicting weather and crop conditions on a 10 day basis. Realtime meteorological data from some 650 stations is received on a daily basis throughout the growing season. Reference files based on 10 day means for each station for relevant parameters are interpolated to derive values for a mesh of 50 x 50 km grid squares. A general semi-deterministic model has been developed to simulate the growth of a generic crop by considering the cumulative impact of the meteorological conditions in the grid-square for each decade. The model is driven by a combined energy balance/water balance module which compares real transpiration with calculated potential transpiration. A set of macros written in Arc/Info is used as the general driver for this system. The inputs, outputs and processing involved are described.
