ECMWF IFS ENS forecast, 6 day, 0.25 degree, virtual validation report

This dataset validation report plots a sample of values from the ECMWF IFS ENS forecast, 6 day, 0.25 degree, 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

All expected source files and variable references are present except the one file noted below. Every partial-coverage variable starts or ends exactly at its documented date.
Values match the source. Independent decodes of source GRIB messages (temperature, humidity, wind, soil temperature) agree with the store to 1e-6.
Maps are correct for every variable, for the main member and a second one (member 23).
Variables are physically consistent with one another. Dew point ≤ temperature, gust ≥ 10 m wind, 100 m wind > 10 m wind, geopotential = 9.80665 × geopotential height, vorticity and divergence agree with the winds, and cloud layers are consistent with total cloud.
Run totals start at 0 and grow with lead time, and static fields are present for the control member at lead 0.

Review notes

Unavailable data

Initialization 2024-09-18T06, lead 111 hours is missing for all variables and members. The source's index for that file does not match its data, so it cannot be read. Unavailable timestamps.

Variable coverage

Some variables cover only part of the archive, matching when ECMWF open data started or stopped publishing them. Initializations outside a variable's range hold NaN.
- From 2024-10-24T12: total_column_water_atmosphere.
- From 2024-11-12T06: wind_gust_10m, maximum_temperature_2m, minimum_temperature_2m, categorical_precipitation_type_surface, precipitation_rate_surface, most_unstable_convective_available_potential_energy_surface, both turbulent surface stress run totals, sea_ice_thickness_surface, sea_surface_height, and sea water velocity u and v.
- Through 2024-11-12T00 only: convective_available_potential_energy_surface, which most_unstable_convective_available_potential_energy_surface replaces.
- From 2025-11-20T12: total_cloud_cover_atmosphere, snowfall_water_equivalent_run_total_surface, snow_water_equivalent_surface.
- From 2026-02-11T12: snow_density_surface.
- From 2026-05-12T06 (control member 0 only): geopotential_height_surface, standard_deviation_of_sub_gridscale_orography_surface, slope_of_sub_gridscale_orography_surface (lead 0 only) and pressure_level/geopotential.
- From 2026-10-20T06: low_cloud_cover, medium_cloud_cover, high_cloud_cover, convective_precipitation_run_total_surface, and total column cloud ice, cloud liquid and rain water.
Not every pressure level covers the whole archive. 100, 150, 400 and 600 hPa start at 2025-01-14T06, and 10 hPa starts at 2026-05-12T06. Earlier initializations hold NaN at those levels.

Source changes over time

ECMWF model upgrades at 2024-11-12T06 (IFS cycle 49r1) and 2026-05-12T06 (cycle 50r1) cause step changes in soil temperature and soil moisture, and at 2026-05-12T06 in sea surface height. Account for these steps when computing climatologies or trends across those dates.
