Introduction
The global production system is used to produce the daily forecasts of pollutants, aerosols and greenhouse gases across the globe. Satellite observations of atmospheric composition are merged with a detailed computer simulation of the atmosphere using a method called data assimilation. The resulting analyses, i.e. maps of atmospheric composition, are used as initial conditions for the daily forecasts of atmospheric composition. Analyses and forecasts for aerosols and chemical species are produced twice a day.
A global production system is also used to assimilate re-processed observations from many satellites for the last few decades, using the same data assimilation process. The result is called reanalysis and it provides a consistent data set that can be used for scientific studies and trend analyses. The current atmospheric composition reanalysis produced by the Copernicus Atmosphere Monitoring Service is the CAMS: Reanalysis data documentation (EAC4).
The IFS model and data assimilation system configurations (48r1)
The model used in the CAMS Global atmospheric composition forecast is the Integrated Forecasting System (IFS) that also produces ECMWF weather forecasts, but with additional modules enabled for aerosols, reactive gases and greenhouse gases that have been developed within CAMS and precursor projects GEMS and MACC. The following processes of atmospheric composition are considered:
- transport of trace gases and aerosols
- injection of emissions
- uptake and release by vegetation and the land and sea surface
- removal by dry deposition at the surface
- removal by scavenging in precipitation
- chemical conversion in the troposphere (CB05) and stratosphere (BASCOE)
- aerosol microphysics
Emissions and surface fluxes of the trace gases and aerosols used in the global CAMS productions are:
- anthropogenic emissions from the CAMS_GLOB_ANT v5.3 with sectoral diurnal cycles and injection heights
- natural and biogenic emissions from the CAMS_GLOB_BIO v3.1 climatologies
- ocean fluxes of DMS from the CAMS_GLOB_OCE v.3.1 climatology
- aircraft emissions of CO2 and NOx from the CAMS_GLOB_AIR v3.1 data set
- biomass burning emissions inferred from satellite observations of fire activity from the CAMS GFAS v1.4 system
- using IS4FIRES injection heights from the CAMS GFAS v1.4 system
For details about simulations and assimilation of chemistry, carbon dioxide, methane and aerosols please see References.
The IFS uses a four-dimensional variational data assimilation method (4D-VAR) for the assimilation of a wide range of meteorological observations as well as satellite retrievals of atmospheric composition.
The IFS model documentation for various model cycles can be found on https://www.ecmwf.int/en/publications/ifs-documentation, including a new section on atmospheric composition aspects. Please note that the IFS cycle changes during the years, and this page documents the current operational cycle (48r1); please have a look at the table below for details of changes from previous cycles.
Configuration for CAMS Global atmospheric composition global forecasts (daily)
Twice a day (at 00:00 and 12:00 UTC), CAMS issues a five-day forecast of global atmospheric composition. The forecast consists of 56 reactive traces gases in the troposphere, stratospheric ozone and seven different types of aerosol: desert dust, sea salt, organic matter, black carbon, sulphate, and (since 9 July 2019) nitrate and ammonium.
The initial conditions of the forecast are obtained by combining a previous forecast with satellite observations of aerosol optical depth, ozone (O3), carbon monoxide (CO), nitrogen dioxide (NO2) , and sulfur dioxide (SO2) through the 4D-VAR data assimilation process.
Satellite observations of fire radiative power (GFAS) from the day before the forecast start are used to derive timely biomass burning emissions for the forecast.
The forecasts are evaluated at quarterly intervals by an external team lead by KNMI and evaluation reports can be found here: https://atmosphere.copernicus.eu/eqa-reports-global-services.
Evolution of the CAMS global forecasting system
The IFS undergoes changes regularly in order to improve the forecast. Changes are listed below with their identifier (Cycle 46r1 for instance) or a specific title when the cycle number did not change.
Implementation date | Cycle | Summary of changes | Resolution/Resolution change | New species |
---|---|---|---|---|
27 June 2023 | 48r1 | Horizontal: 40km, Vertical: 137 levels | See parameters in green in tables below | |
1 Feb 2023 | 47r3 | Assimilation of AOD from VIIRS | none | |
15 Dec 2022 | 47r3 | Update of the T159 background error covariance wavelet file to use the correct NWP background errors. The update leads to considerably improved NWP forecast scores.

Data access
The data is now available from the Atmosphere Data Store (ADS), either interactively through its download web form or programmatically using the CDS API service:
CAMS global atmospheric composition forecasts
Currently only strings should be used as keyword values in a CDS API request for ADS data.
Analysis data are not available on the ADS webform but they can be downloaded using the CDS API service. In the request, the keyword 'type' and 'leadtime_hour' have to be set as 'analysis' and '0' respectively. Please have see the following example:
A subset of the CAMS Global atmospheric composition forecast data for the latest three days can also be accessed through the FTP service. For a list of variables available on the FTP please see here.
Access to CAMS global air quality forecast and analysis data through the ECMWF public Web API service ended on 30 June 2021.
To move to the ADS service, please follow our guidelines on How to migrate to CDS API on the Atmosphere Data Store (ADS).
Users with direct access to MARS can browse the data on the MARS catalogue under class=mc and expver= 0001.
Data availability (HH:MM)
CAMS Global analyses and forecasts:
00 UTC forecast data availability guaranteed by 10:00 UTC
12 UTC forecast data availability guaranteed by 22:00 UTC
It is possible that the data will be available earlier but without guarantee.
Variations in delivery times may occur due to the non-operational nature of this ADS service, as issues may arise which cause delays. For any time-critical work, users should rely on ECMWF FTP service dissemination system instead.
Spatial grid
CAMS Global atmospheric composition forecasts data currently has a resolution of approximately 40 km (approximately 0.35 degrees). The data are archived either as spectral coefficients with a triangular truncation of T511 or on a reduced Gaussian grid with a resolution of N256. These grids are so called "linear grids", sometimes referred to as TL511.
PLEASE NOTE: CAMS Global atmospheric composition forecasts data available from the ADS has been pre-interpolated to a regular 0.4°x 0.4° latitude/longitude grid. The keyword 'grid' is not supported in CDS API requests on the ADS.
Temporal frequency
The CAMS Global 5-day forecasts run twice daily from 00 and 12 UTC and the data are available every hour (for surface fields) and every 3 hours (for model- and pressure-level fields). The analyses are available every 6 hours at 00 UTC, 06 UTC, 12 UTC and 18 UTC.
From 21 June 2016 CAMS Global data is produced twice daily, with basetime 00:00 and 12:00 UTC.
Until 21 June 2016 CAMS Global data was produced only once a day, with basetime 00:00 UTC.
Data format
Model level fields are in GRIB2 format. All other fields are in GRIB1, unless otherwise indicated. NetCDF format is available on ADS but it is experimental.
From cycle 48R1, there are important changes to the GRIB encoding for model levels fields, relating to packing and GRIB tables. Please see this page for full details: Implementation of IFS cycle 48r1 for CAMS#ChangetoGRIBencoding
The 'packingType' can be changed using ECMWF's ecCodes:
# CCSDS -> simple grib_set -r -s packingType=grid_simple in.grib2 out.grib # Simple -> CCSDS grib_set -r -s packingType=grid_ccsds in.grib out.grib2
Users are advised to use data in GRIB format. If this is not possible, users should download the data in GRIB and convert them to NetCDF with sufficient precision such that data values are correctly represented.

Satellite observations
Satellite observations are used by CAMS to constrain the global forecast model, ensuring the forecasts are as accurate as possible. The process of merging the numerical forecast model with the observations is called data assimilation.
The CAMS Global production system uses satellite data in its 4-dimensional variational (4D-Var) data assimilation system to constrain the initial atmospheric state that is used for the 5-day forecast. Apart from all the meteorological observations that form part of the ECMWF numerical weather prediction system, CAMS uses additional observations on atmospheric composition. Three categories of observations are listed below. The assimilated observations are the observations that are currently used to constrain the model; the monitored observations are the observations that are being tested for future implementation; and the planned observations are observations that are being considered for future implementation in the CAMS system.
Satellite data monitoring statistics are available here.
Evaluation and Quality Assurance reports
The global forecasting system is continually being evaluated to ensure the output meets the expected requirements. Comprehensive Evaluation and Quality Assurance (EQA) reports are provided on a quarterly basis. Before each upgrade of the global forecasting system, the new system is tested and evaluated, and a so-called "e-suite EQA report" is produced. All reports are available here.
Quality monitoring graphics
CAMS uses a multitude of independent data sets to routinely monitor its global forecasts. It works with various data providers, acquiring the observations with appropriate timeliness and generating graphics that show the differences between the forecasts and the independent observations.

Known issues
Issue type | Description | Cycle | Note |
---|---|---|---|
High SO2 values over north-eastern Brazil | High SO2 values over north-eastern Brazil on 18 January 2020 and 16 June 2020 at 06:00:00 are artificial and are due to the assimilation of some spurious satellite observations of SO2 in one of the datasets used by CAMS. | 47r1 | |
BC concentrations in the mid/upper troposphere tend to be too high | Some of the low background BC concentrations in the mid/upper troposphere tend to be too high as an artefact of the data assimilation as it improves the total AOD. (They're still very low compared to polluted areas, but can be somewhat higher than they should.) This aspect of the impact of data assimilation on aerosol speciation is something that we're continuing to look into. (The accompanying "control run", a model-only product with no AOD assimilation, can often has a more realistic speciation and vertical profile in this regard, but at the cost of a poorer agreement with observations of total AOD.) | 47r1 or 46r1 | |
Dust emissions are too high in cycle 46r1 | See details here: Dust emissions are too high in Cycle 46r1 | 46r1 | |
AOD and PM data are zero at forecast step 0 | Aerosol optical depth (AOD) and particulate matter (PM10, PM2.5) at forecast step 0: all values are zero | 41r1 and 43r1 |
