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.
|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.|

|Specifications of cmeteo_grid_weather|
Cmeteo_region_weather is a replacement for a variety of datasets to which cmeteo need to fill up with output. The results of cmeteo must be placed into datasets with an appropriate spacial resolution like NUTS regions or agri-environmental zones. In general, datasets for NUTS-regions are pre- or postfixed with 'nuts'; datasets for agri_environmental zones are pre- or postfixed with 'zonal'. Per thema, the structure of datasets for both resolutions are very similar.

1) If an attribute for the offset of the day isn't available, the day-offset in cmeteo grid weather will be filled with a neutral value (0). This value doesn't influence the processing.

Cmeteo_region_weather is a replacement for a variety of datasets, both for themes (e.g. cgfs-his, cgms) and for resolutions (e.g. NUTS regions, agri-environmental zones), to which cmeteo need to fill up with output. In general, datasets for NUTS-regions are pre- or postfixed with 'nuts'; datasets for agri_environmental zones are pre- or postfixed with 'zonal'.

|Specifications of cmeteo_aggregation_areas|
Cmeteo_aggregation_areas is a replacement for a some of datasets from which cmeteo need to gather input concerning sizes of surfaces.
