GEM-DS 2.5 km
Canadian GDPS (GEM global) guidance corrected against URMA on a 2.5 km grid with a station layer, the same method as ECMWF-DS and GFS-DS. Three-hourly to 240 hours from the 00 and 12 UTC runs. Native-window verification is distinct from full-day market verification.
What to inspect
Follow successive runs for the same target date. Compare error, bias and interval coverage on shared stations and dates. A sharper forecast is useful only when its uncertainty remains reliable.
Separate native-window guidance; no compatible full-day market score

Raw models, corrected station products and downscaled grids forecast different things. Market recap shows its decision cutoff, settlement basis and coverage. Missing forecasts are unavailable, never zero. Inclusion in this directory or recap does not imply inclusion in a trading blend.
