Environment and Climate Change Canada Products Covering CCRN Domain

Environment Canada data that cover the CCRN research domain are available in ASCII, grib2, and Environment Canada standard (FST) formats by request to daniel.princz@usask.ca or bruce.davison@canada.ca. The GEM dataset contains hourly data for the seven forcing variables required by MESH/CLASS/SVS from 2002 to present at a 10 km or 15 km resolution. The CRCM5 dataset contains hourly data for the seven forcing variables required by MESH/CLASS/SVS from 1958-2014 at resolutions of 0.11, 0.22, and 0.44 degrees. The CaPA (precipitation analysis) dataset contains 6-hourly and daily data for accumulated precipitation from 2002 to present at a 10 km resolution. The RDPS dataset contains 3-hourly data for four daily forecasts to 36 hours for all pressure fields from 2010/11/01 to present at a 10 km resolution. The HRDPS dataset contains hourly data, as well as half-hourly data for some variables, for four daily forecasts to 36 hours for all pressure fields from 2014/11/12 to present at a 2.5 km resolution.

Details:

Hourly data are available from GEM and CRCM5 for these forcing variables: incoming shortwave radiation, incoming longwave radiation, precipitation rate, air temperature, wind speed, direction, and U and V components, barometric pressure, and specific humidity. GEM is available at a 15 km resolution from 2002-2012/10/03 and at a 10 km resolution from 2012/10/03 to present. CRCM5 is available at resolutions of 0.11, 0.22, and 0.44 degrees from 1958-2014. Both datasets cover the CCRN domain. At present, these are available in ASCII, grib2, and Environment Canada standard (FST) formats, by request to daniel.princz@usask.ca. Both sets are planned to be converted to grib2 format for general accessibility to the University of Saskatchewan Global Institute for Water Security (GIWS).

6-Hourly and daily data are available from CaPA (precipitation analysis) for these forcing variables: accumulated precipitation or precipitation rate. The data are available at a 10 km resolution, and cover the CCRN domain. Data from 2013 to 2015 are available in grib2 format to GIWS. Data are also available from 2002 to present in ASCII, grib2, and Environment Canada standard (FST) format, by request to daniel.princz@usask.ca or bruce.davison@canada.ca. The remaining years of the dataset, from 2002-2012, are planned to be converted to grib2 format for general accessibility to GIWS.

All four daily forecasts to 36 hours are available for all pressure fields from RDPS and HRDPS (regional and high resolution deterministic forecasts). RDPS contains 3-hourly records, and is available at a 10 km resolution. HRDPS contains hourly records, as well as half-hourly records for some variables, and is available at a 2.5 km resolution. Spot dates from 2010/11/01 for RDPS and from 2014/11/12 for HRDPS (both to present) in the grib2 format are currently available by request to daniel.princz@usask.ca, bruce.davison@canada.ca, or branko.zdravkovic@usask.ca.
