| # 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](https://github.com/andrewnakas/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 `YYYY-Www/` |
|
|
| ## Usage |
|
|
| ```python |
| import xarray as xr |
| ds = xr.open_zarr("https://huggingface.co/datasets/nakas/nbm-conus-analysis/resolve/main/2026-W23") |
| ds.tmean.isel(time=0).plot() |
| ``` |
|
|
| Concatenate weeks along `time` to span longer periods. |
