ECCC precip grids (ECCC_PRECIP_GRID)

Upstream: ECCC Datamart HRDPA / RDPA accumulated precipitation in GRIB2; HREPA (High Resolution Ensemble Precipitation Analysis, CaPA-HREPA) in NetCDF on the same Datamart layout (no GRIB conversion—Datamart delivers .nc). Product overview: MSC HREPA readme.

Transport: HTTP GET via coldcast.download.download_requests().

Auth: None for typical Datamart access.

CLI: coldcast download eccc_precip_grid [--model HRDPA|RDPA|HREPA|HREPA_PCT25|HREPA_PCT75]

Settings: ECCC_PRECIP_GRID with default_model (e.g. RDPA), per-model hour_list, delay_hours, num_days_back.

HREPA FEWS NetCDF (optional): On HREPA model keys only, you may set fews_netcdf.enabled: true. After each successful download, Coldcast writes an additional NetCDF next to the raw file (suffix from output_suffix, default _fews → *_fews.nc): optional geographic clip (clip_to_bbox / clip_bbox, merged per key with top-level bounding_box; same lon/lat keys as ECMWF YAML examples), Conventions set to CF-1.8, optional output_variable_name to rename the main precip variable (e.g. for FEWS), and optional omission of ConfidenceIndex (include_confidence_index: false). Raw Datamart files are unchanged.

Code: coldcast.sources.eccc_precip_grid

HRDPA/RDPA remain GRIB2; HREPA is NetCDF end-to-end.
