NOAA HRRR analysis, virtual validation report

This dataset validation report plots a sample of values from the NOAA HRRR analysis, virtual dataset over time and across space, comparing where possible to a previously validated reference dataset. It also reports the quantity of unavailable values and their associated timestamps. These analyses are one layer of a multi-layered dataset validation process we perform at dynamical.org and also provide users a preview of the dataset contents.

Summary

This dataset has been reviewed and is ready for use.

What looks good

Every sampled chunk reference decoded. 3,019 references across 20 time regions, 5 forecast leads and 3 vertical levels per grouped variable, with zero failures.
The grid and coordinates were verified numerically, not just by eye. The corners of the plotted Lambert Conformal grid match an independent projection calculation exactly, and the maximum snow depth in the domain resolves to 46.841°N, 121.776°W — the summit of Mount Rainier — in both this dataset and the raw source file. Terrain, land-sea mask, ice cover and vegetation-type coastlines all coincide.
The archive is complete at every hour after 2020-11-12.
Physical relationships hold across variable families. Total cloud cover is at least the maximum of the high, medium and low cloud covers; 80 m wind exceeds 10 m wind at 97.5% of cells and gusts exceed the 10 m wind at 99.7%; convective available potential energy is non-negative and anti-correlated with the lifted index; dew point stays below temperature; and shortwave radiation is zero at night.
Spot checks match the source files byte for byte for the convective energy family, relative vorticity, hail diameter, vegetation, baseflow runoff and smoke mass density.

Review notes

Individual variables carry their own quirks in their comment metadata. The notes below apply across the archive.

Changes in the source over time

Clear-air visibility_surface is capped at 60 km before 2018-07-12 and 90 km after. Treat capped values as "at least this far" and do not compare across that date.
The otherwise static roughness and terrain fields were updated by the source — surface_roughness_surface on 2018-07-12 and geopotential_height_surface on 2020-12-02 — across most of the domain, mostly by small amounts.
model_level/turbulent_kinetic_energy values of exactly 0.0005 (before 2020-12-02) or 0.00005 (after) mean "below the stored resolution", not a measurement.
The two model_level/number_concentration_*_aerosol fields lose nearly all spatial structure between 2019-06-12 and 2020-12-01.
The vegetation variables are zeroed at urban and water cells in scattered windows, including 2022-08-01 to 2022-08-10, 2023-01-04 and 2024-11-07.

Availability

Variables begin at HRRR model version boundaries. 2016-08-23, 2018-07-12 and 2020-12-02. The availability plot below shows each variable's own start.
Source outages total 4,323 of 104,353 hours, all of them before 2020-11-12 and concentrated in 2016.
