NOAA GFS analysis validation report

This dataset validation report plots a sample of values from the NOAA GFS analysis 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.

Report generation start time: 2026-07-21T20:31:49 UTC

Summary

This dataset has been reviewed and is ready for use. This validation pass adds four new variables at 80 m above ground — 80 metre temperature, 80 metre pressure, and the 80 metre U and V wind components — to the previously validated set of 21 variables; all four are complete over the archive and physically consistent with the neighbouring 10 m and 100 m fields (see What looks good). Two known items remain, unchanged from prior validation: an upstream data gap on 2022-11-29 → 2022-11-30, and the expected first-timestamp NaN for accumulated precipitation (see Review notes).

What looks good

The four new 80 m variables are correct. 80 metre temperature, 80 metre pressure, and the 80 metre U and V wind components are complete over the full 2021-05 → 2026-07 archive, with no gaps beyond the shared upstream one noted below. Their spatial maps have correct global geometry and land–sea placement: 80 metre temperature closely tracks 2 metre temperature (2024-01-15 snapshot: range −53.5 to +37.5 °C, mean 3.8 °C, versus −54.5 to +38.8 °C, mean 3.8 °C for 2 metre temperature); 80 metre pressure reproduces terrain (low over the Tibetan Plateau, the Andes, and Antarctica) and sits about 1 kPa below surface pressure, as expected for the added height; and the wind components are near-zero-mean with the coherent mid-latitude zonal (U) and synoptic (V) structure, slightly stronger than the 10 metre winds as expected for the boundary-layer wind profile. Full-period series show smooth seasonal and diurnal cycles with no unit step-changes, and histograms show no sentinel spikes or quantization banding. These variables have no NOAA GEFS counterpart, so they are validated without a reference overlay.
Across all variables the validation maps match the NOAA GEFS reference in continental placement and feature alignment on the 0.25° global grid (latitude north-up, longitude −180° to +180°), with no flipped axes, missing seams, or off-grid coordinates.
Validation and reference histograms overlap for every comparable variable, with no unit-scale offsets. Physical ranges are realistic across the global snapshot at 2024-01-15T00:00: temperature roughly −55 to +39 °C, surface pressure 48.7 to 106.4 kPa, mean sea-level pressure 96.5 to 106.3 kPa, 10 m winds within ±39 m/s, precipitable water 0.22 to 76.5 kg/m², downward shortwave radiation 0 to 1004 W/m², downward longwave radiation 93 to 488 W/m².
Time series at both sampled points (lat 45.0°N, lon −100.0°E in the North American interior; lat −35.0°S, lon 155.0°E in the Tasman Sea) track the reference closely for temperature, pressure, humidity, wind, and precipitable water; diurnal cycles in shortwave radiation and 2 m / 80 m temperature are in phase; categorical and accumulated variables align with reference timing.
No unexpected nulls outside the documented upstream gap. No quantization banding, sentinel-value bleed-through (the 20 km cloud-ceiling and −50 % frozen-precipitation-fraction values both also appear in the GEFS reference and are upstream GRIB conventions for "no ceiling" / "no precipitation"), or unit mismatches were observed.

Review notes

Unavailable values 2022-11-29 → 2022-11-30 (approximately 16 hours, all variables). The upstream s3://noaa-gfs-bdp-pds/ archive published .idx byte-index sidecars for the 2022-11-29T18Z, 2022-11-30T00Z, and 2022-11-30T06Z init cycles whose byte offsets do not align with the GRIB message boundaries in the corresponding GRIB files; the byte-range download path trusts those offsets and the partial bytes returned are not valid GRIB. Direct inspection of the underlying GRIB files confirms the data is intact at the source — only the published index is wrong. We are attempting to have these fixed at the source and will backfill once that has happened. Affected timestamps for instant variables: 2022-11-29T20:00, 21:00; 2022-11-30T02:00, 05:00, 08:00, 09:00, 10:00, 11:00 (8 per variable). Accumulated precipitation (precipitation_surface) has 12 additional 1-hour timestamps across the same window because deaccumulation also requires the adjacent leads. Visible in availability_temperature_2m.png and every other availability_<var>.png.
First timestamp of precipitation_surface (2021-05-01T00:00:00) is NaN at every spatial location. The analysis dataset derives accumulated precipitation by deaccumulating between adjacent GFS forecast leads, and there is no prior step before the dataset's start to deaccumulate against. This is expected; no other variable is affected. Visible in availability_precipitation_surface.png.
