ECMWF IFS ENS forecast, 15 day, 0.25 degree, virtual validation report

This dataset validation report plots a sample of values from the ECMWF IFS ENS forecast, 15 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.

Report generation start time: 2026-11-11T15:06:01 UTC

Summary

This dataset has been reviewed and is ready for use.

What looks good

Every expected source file is present, and every variable is present at every initialization in its coverage period.
Values match the source. Several members, including the control, were checked against source GRIB messages.
Maps, coordinates and units are correct. The pressure-level coordinate maps to the right data, and geopotential = 9.80665 × geopotential height.
Variables are physically consistent with one another. Vorticity and divergence agree with the winds, upward motion coincides with high humidity, 100 m winds exceed 10 m winds, gusts exceed sustained winds, and run totals never decrease with lead time.
Short-lead forecasts track NOAA GEFS analysis.

Review notes

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 2024-11-12T12: 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. Its plots at this report's snapshot are therefore empty; see its spatial and temporal plots from 2024-08-01T00.
- 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 2026-05-12T12 (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 2026-10-20T12: 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 2025-01-14T12, and 10 hPa starts at 2026-05-12T12. Earlier initializations hold NaN at those levels.

Source changes over time

ECMWF model upgrades at 2024-11-12T12 (IFS cycle 49r1) and 2026-05-12T12 (cycle 50r1) cause step changes in soil temperature and soil moisture, and at 2026-05-12T12 in sea surface height. Account for these steps when computing climatologies or trends across those dates.
