This chart provides information on the verification of forecasts of Accumulated Cyclone Energy ...

The ECMWF seasonal forecasts (SEAS5) are produced every month with a 51-member ensemble at a ...

The leaf area index determines the degree of evapotranspiration. The index varies in a climatological way in the model, month by month (and so will not change in a different way if there is anomalous weather)...

Mean wave period is the spectrally averaged period of the waves. Wave periods are shown in seconds using colour shading – click on the middle icon to the bottom right for the scale...

This chart shows probability information regarding mean wave period derived from the ECMWF ...

This chart shows probability information regarding significant wave height derived from the ...

These charts show the probability of various mean periods of ocean waves 10-15 days ahead. The ...

The ECMWF seasonal forecasts (SEAS5) are produced every month with a 51-member ensemble at a ...

Mean windsea wave direction is the spectrally averaged direction of propagation of the windsea waves (weighted by wave height). Arrow length is proportional to the speed of wave propagation...

Significant windsea wave height can be shown to correspond to the average wave height of the top one-third highest windsea waves. Wave heights are shown in metres using colour shading...

This dataset provides gridded modelled hydrological time series forced with medium-range meteorological forecasts. The data is a consistent representation of the most important hydrological variables across the European Flood Awareness System (EFAS) domain. The temporal resolution is sub-daily high-resolution and ensemble forecasts of:

River discharge
Soil moisture for three soil layers
Snow water equivalent

These charts show probability of various heights of significant waves 10-15 days ahead. The ...

Mean total swell wave direction is the spectrally averaged propagation direction of the swell waves (weighted by wave height) of the part of the spectrum that is NOT windsea...

Wave height is the vertical distance between trough and crest. Wave period is the time between the passage of one wave crest and the next. The arrow direction is the direction the waves are moving towards...

The charts show mean frequency and accumulated cyclone energy of tropical storm activity. ...

This chart provides information on the verification of forecasts of the expected number of ...

The charts show the evolution of existing and potential tropical cyclone activity. ...

Lower values mean that more radiation is absorbed at the earth's surface while higher values mean more is reflected back to space. Albedo depends on the characteristics of the underlying surface and...

This dataset provides annual air quality reanalyses for Europe based on both unvalidated (interim) and validated observations.

This dataset is part of the ECMWF Atmospheric Composition Reanalysis focusing on long-lived greenhouse gases: carbon dioxide (CO2) and methane (CH4). The emissions and natural fluxes at the surface are crucial for the evolution of the long-lived greenhouse gases in the atmosphere. In this dataset the CO2 fluxes from terrestrial vegetation are modelled in order to simulate the variability across a wide range of scales from diurnal to inter-annual.

This dataset is part of the ECMWF Atmospheric Composition Reanalysis focusing on long-lived greenhouse gases: carbon dioxide (CO2) and methane (CH4). The emissions and natural fluxes at the surface are crucial for the evolution of the long-lived greenhouse gases in the atmosphere. In this dataset the CO2 fluxes from terrestrial vegetation are modelled in order to simulate the variability across a wide range of scales from diurnal to inter-annual.

This data set contains net fluxes at the surface, atmospheric mixing ratios at model levels, and column-mean atmospheric mixing ratios for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N20).

This dataset provides geographical distributions of the radiative forcing (RF) by key atmospheric constituents. The radiative forcing estimates are based on the CAMS reanalysis and additional model simulations and are provided separately for...
