This CanadaMeteo data import is used for targeted access of Observation Summary Data Observations summary data in XML format.
The files that are downloaded and imported can be found at
Imports XML data that follows the xmlns="http://dms.ec.gc.ca/schema/point-observation/2.1" shema.
Files can be found in this directory: http://dd.meteo.gc.ca/observations/xml/
Overview:
.
The first set of data (member) contains information that is not specific to one location, it is not imported.
Data concerning record temperatures, record rain, record snow, since when temperature and precipitation data is available, present weather and tendency characteristic are ignored. (Thus fields that do not contain data measured at sampling time).
Measurements with no "value" are ignored.
Wind direction is calculated from code to degrees. For location ID climate station number is used.
Example:
parser is included in Delft-FEWS versions 2017.02 and higher.
This documentation contains:
1) Data Provider Documentation
2) Sample Configuration
This data import is available since Delft-FEWS 2018.02 and a patch more recent then January, 2020.
Please comment if anything further is needed or requires updating.
1) Data Provider Documentation

Configuration Notes:
- The first set of data (member) contains information that is not specific to one location, it is not imported.
- Data concerning record temperatures, record rain, record snow, since when temperature and precipitation data is available, present weather and tendency characteristic are ignored. (Thus fields that do not contain data measured at sampling time).
- Measurements with no "value" are ignored.
- Wind direction is calculated from code (for example, NW for NorthWest) to degrees. For location ID climate station number is used.
- If, in the import module, a RegionDirectory is configured (for the purpose of importing data for, say, a single Province only), special attention should be paid to make sure that the locationSet that data is imported to, includes locations that are available in the directory specified.
- If data is not available for the chosen times, en empty time series set is returned.
- It is practical to configure either a short time period, or other restrictions to prevent running out of local memory.
Locations and id mapping
Two files used for Locations and IdMapping are linked here.
- Link: A list of Environment Canada locations from which data can be imported.
- Note that the 'external location IDs' are in the column "
# MSC
"; these correspond to the XML data file'sclimate_station_number.
- This means you will either need to set these as your Delft-FEWS locationID
- Alternatively, you need to import the MSC column as an attribute and use an id-mapping function to reference that, for example
<locationIdFunction internalLocationSet="EC_stations" externalLocationFunction="@climate_station_number@"/>
where, in the locationSets,climate_station_number
is an attributeID defined from the associated column in the .csv file that stores the locations:<attribute id="climate_station_number"><text>%# MSC%</text></attribute>
.
- Note that the 'external location IDs' are in the column "
- Link: IdMappingFile
Note that both files were valid at the time of upload to the WIKI. Any changes made by Environment Canada, to either the locations or the naming of parameters, will not be automatically reflected in these attachments.
These files adhere to a schema: xmlns="http://dms.ec.gc.ca/schema/point-observation/2.1" An example of such an xml data file:

If region directory is configured, special attention should be payed to make sure that the wanted locations are found in the directory specified.
If data is not available for the chosen times, en empty time series set is returned.
It is practical to configure either a short time period, or other restrictions to prevent running out of local memory.
The importer should be registered in FEWS Config/RegionConfigFiles/ModuleInstanceDescriptors.xml. Locations of the wanted time series should be registered in Config/RegionConfigFiles/Locations.xml. Parameters (such as mean sea level) should be registered in Config/RegionConfigFiles/Parameter.xml.
