Introduction

Cmeteo stands for CORINE-meteo. Cmeteo can be seen an application suite to aggregate weather indicators from grid resolution to a regional type of division. 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. 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.

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

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. 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. As cmeteo only can use one structure for grid weather, some logic must be applied to transform the various sets into unified representations. This transformation is implemented as a view (standard selection) on each of the original datasets while renaming the attributes and eventually suppliyng neutral or valuable data for missing attributes. The dataset cmeteo_grid_weather is composed of the most wide combination of attributes of the various underlying datasets. Below a summary of some sets in various schemas and the definition of cmeteo_grid_weather domain schema: CGMS_EUR_08 CGFS_EUR_09 CGFS_EUR_09 CGMS_ASIA_08 dataset: grid_weather ecmwf_his_downscaled_data ecmwf_eps_downscaled_data ecmwf_downscaled_data cmeteo_grid_weather attributes: grid_no grid_no grid_no ecmwf_grid_no grid_no NN number(10) day mdate mdate mdate day NN date - 1) - 1) date_offset - 1) day_offset NN number(10) - 2) - 2) member_no - 2) member_no NN number(10) maximum_temperature temperature_max temperature_max temperature_max max_temperature NN number(3,1) minimum_temperature temperature_min temperature_min temperature_min min_temperature NN number(3,1) - 3) temperature_mean temperature_mean temperature_mean mean_temperature NN number(3,1) - 4) temperature_dew temperature_dew temperature_dew dew_temperature NN number(3,1) vapour_pressure vapour_pressure vapour_pressure vapour_pressure vapour_pressure NN number(4,2) windspeed wind_speed wind_speed wind_speed wind_speed NN number(5,1) rainfall precipitation precipitation precipitation precipitation NN number(4,1) e0 e0 e0 e0 e0 NN number(4,2) es0 es0 es0 es0 es0 NN number(4,2) et0 et0 et0 et0 et0 NN number(4,2) calculated_radiation radiation_global radiation_global radiation_global global_radiation NN number(6) snow_depth snow_depth snow_depth snow_depth snow_depth number(6,2) 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. 2) For sets that doesn't contain an attribute for members, a member_no: 1 will be supplied in cmeteo grid weather. 3) If an attribute for the mean or daily temperature doesn't exist, this value will be estimated as the mean value of minimum and maximum temperature of the day. Cmeteo will process this value and produces a result for it. 4) A dummy value (0) for the dew temperature wil be supplied to cmeteo grid weather for sets lacking such an attribute. Cmeteo will process this value and produces a result for it, so precautions must be taken to supply these results to the output table.

Specifications of cmeteo_region_weather

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'. 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 essential indicators for which cmeteo delivers output. Per theme, the structure of datasets for both resolutions are very similar. As cmeteo only can use one structure for region weather, some logic must be applied to transform the various sets into unified representations. This transformation is implemented as a view (with the possibility to insert/update values) on each of the original datasets while renaming the attributes. As the dataset cmeteo_region_weather delivers the most wide combination of attributes of the various underlying datasets, some precautions must be taken to prevent some useless attributes being placed into the final dataset. Functionality for this is located in a technical construct (trigger) which is connected to the views. In a dynamical way cmeteo_region_weather will be linked to the proper dataset according to the theme and the appropriate spacial resolution to deliver the results of cmeteo. Below a summary of some sets in various schemas and the definition of cmeteo_region_weather domain schema: CGMS_EUR_08 CGFS_EUR_09 CGFS_EUR_09 CGMS_ASIA_08 datasets: nuts_weather ecmwf_his_downscaled_nuts ecmwf_eps_downscaled_nuts nuts_weather cmeteo_region_weather zonal_weather ecmwf_his_downscaled_zonal ecmwf_eps_downscaled_zonal attributes: reg_map_id reg_map_id reg_map_id reg_map_id reg_map_id NN number(10) landcover_id landcover_id landcover_id landcover_id landcover_id NN number(10) threshold threshold threshold threshold threshold NN number(3) day mdate mdate day day NN date - 1) - 1) date_offset - 1) day_offset NN number(10) - 2) - 2) member_no - 2) member_no NN number(10) maximum_temperature temperature_max temperature_max max_temperature max_temperature NN number(3,1) minimum_temperature temperature_min temperature_min min_temperature min_temperature NN number(3,1) daily_temperature temperature_mean temperature_mean daily_temperature mean_temperature NN number(3,1) - 3) temperature_dew temperature_dew dew_temperature dew_temperature NN number(3,1) vapour_pressure vapour_pressure vapour_pressure vapour_pressure vapour_pressure NN number(4,2) windspeed wind_speed wind_speed wind_speed wind_speed NN number(5,1) rainfall precipitation precipitation precipitation precipitation NN number(4,1) e0 e0 e0 e0 e0 NN number(4,2) es0 es0 es0 es0 es0 NN number(4,2) et0 et0 et0 et0 et0 NN number(4,2) calculated_radiation radiation_global radiation_global global_radiation global_radiation NN number(6) snow_depth snow_depth snow_depth snow_depth snow_depth number(6,2) 1) The value for the offset of the day as produced by cmeteo will not be inserted into indicated sets. 2) The value for the member as produced by cmeteo will not be inserted into indicated sets. 3) As input for this attribute was lacking cmeteo produced a dummy value (0). This value must be omitted.
