Datasets

CAMS produces global forecasts for atmospheric composition twice a day. The forecasts consist of more than 50 chemical species (e.g. ozone, nitrogen dioxide, carbon monoxide) and seven different types of aerosol (desert dust, sea salt, organic matter, black carbon, sulphate, nitrate and ammonium aerosol). In addition, several meteorological variables are available as well.

Emissions of atmospheric pollutants from biomass burning and vegetation fires are key drivers of the evolution of atmospheric composition, with a high degree of spatial and temporal variability, and an accurate representation of them in models is essential.

This data set contains gridded distributions of global anthropogenic and natural emissions.

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).

Single prediction that uses

IFS Medium range Control forecast offers "High Frequency products"  

Not all post-processed Products are available at 06/18 runs or in hourly steps.

IFS Medium-range Control forecast (Wave) is coupled to the IFS Medium-range Control forecast and it provides direct output "High Frequency products":

The model computes between the latitudes -78 and 90, the output grid is artificially extended to -90.

A routine inter-comparison of wave model forecast verification data was first established in 1995, developed around the exchange of model forecast data at an agreed list of moored buoy sites at which instrumented observations of significant wave height, wave period and wind speed are available over the WMO GTS.

ECMWF has adopted an open data policy, with the objective of expanding free and equitable access to high‑quality numerical weather prediction data for the global meteorological community. This shift supports the socio‑economic benefits of weather and climate information and aligns with WMO policies on international data exchange and capacity development for National Meteorological and Hydrological Services (NMHSs).
