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.
Tools needed by cmeteo
Cmeteo uses functionality which is implemented in several other 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|
In various schemas datasets containing weather indicators do vary both in name of the set and in names of the attributes. Also the collection of the attributes may vary. However, all the sets contain the indicators that are essential to process cmeteo. On the other hand cmeteo_grid_weather is not a dataset on it's own. In any case it is a view on one of these sets. The one to choose depends on the parameters to start the cmeteo process.
The dataset cmeteo_grid_weather is composed of the most wide combination of attributes of the various underlying datasets. If a set doesn't contain a certain attribute a valuable dummy will be selected.
Below a summary of some sets in various schemas and the definition of cmeteo_grid_weather
1) This value is only a dummy. In cmeteo it does not influence the processing of other attributes. Precautions must be taken to store this attribute in the output dataset.
