NOAA NBM CONUS Daily Analysis (Zarr)
Daily best-estimate analysis derived from NOAA NBM (National Blend of Models) CONUS forecasts, on the native ~2.5 km Lambert conformal grid (2345 x 1597). Built by nbm-to-zarr, dynamical.org-style.
- Variables: tmean / tmax / tmin (degC), precip (mm), srad (MJ/m2/day)
- Construction: best estimate for day D = lead-day 1 of that day's 00z NBM init
- Coverage: rolling backfill from 2020-10-01 (AWS NBM archive floor) to present
- Layout: one standalone Zarr per ISO week under
