Introduction

Cmeteo stands for CORINE-meteo. Cmeteo can be seen an application suite to process meteo data as found in e.g. the CGMS.grid_weather dataset. It aggregates and translates meteo indicators according to some spatial and thematic specs. Think of meteo indicators on temperature (maximum, minimum, mean or daily), windspeed, precipitation, radiation. Also indicators as potential transpiration, evaporation may be included. In the context of MARS, the weather indicators are given per grid. These indicators will be aggregated to spatial themas like NUTS or agri environmental regions, or translated/adjusted for landcovers of interest like crops, etc. Translation will be accompanied by aggregation. See ..(somewhere else in this wiki).. for more detailed description of cmeteo.

The cmeteo package is designed to operate in several environments which may differ in both input as output datasets. All these environments need to have the basic data (both input and output) available for the CMeteo process.

Software tools needed by cmeteo

Cmeteo uses functionality which is implemented in several other software tools. The major ones are listed in the following table.

tool remarks
REGLISTS supplies specific lists of regions directed by input parameters.
MRS_PROCESS contains common used functionality for processing more complex programs like cmeteo.
ADD_PROCESS_LOG procedure to send some info to a logtable.
ADD_PROCESS_METRICS procedure to send some data, retrieved during processing, to a logtable.
MRS_STATS generic tool to collect some metrics during processing.
MRS_HTTP generic tool to handle some messages.
DATE_GENERATOR generic tool to generate specific lists of dates according to the input paramaters.
