Available data

The Weather Research Forecast (WRF) V4.2.1 meteorological data for all of Alberta, for 2015 to 2019, is available from CCD Health Systems. The data can be extracted using software (MMEU2) to produce suitably formatted data for input into regulatory models.

The availability of standard meteorological data provides easily accessible resources and reduces inconsistencies in meteorological data quality.
