Implementation date	Cycle	Summary of changes	Resolution/Resolution change	New species
27 June 2023	48r1	Atmospheric composition, Meteorology, GRIB encoding	Horizontal: 40km, Vertical: 137 levels	Details available hereSee 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. As a consequence, smaller changes to AOD and upper tropospheric and lower stratospheric ozone are also expected.	Horizontal: 40km, Vertical: 137 levels	none
22 Feb 2022	47r3	A fix of low-level T/q in fog conditions was introduced with the 12 UTC cycle on 22 Feb 2022	Horizontal: 40km, Vertical: 137 levels	none

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.

...

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.

...

Note

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:

Code Block
# 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

...

Physical characteristics of the different types of aerosols (i.e mass density, the radius mode and geometric standard deviation of the lognormal size distribution and the bin limits and hygroscopic factor), are available in Rémy et al. (2019).

The suggested reference for the IFS aerosol optical properties and hygroscopic growth tables is Bozzo at al (2020) and the new CY48R1 documentation: https://www.ecmwf.int/en/elibrary/81374-ifs-documentation-cy48r1-part-viii-atmospheric-composition, chapter 5.

Fast access	Parameters labelled as "Fast access" are stored on disk while parameters labelled as "slow access" are stored on tape. Retrieval of this data will be MUCH SLOWER than disk-resident data.
	Parameters highlighted in green were introduced with the new upgrade (48R1).

Note

Many forecast meteorological variables are available with 6 days delay from present and data returned from API requests will have these meteorological fields filtered out automatically.

Please note the following forecast model level meteorological variables are available without any time restriction:

Geopotential
Specific humidity
Temperature
U-component of wind
V-component of wind
Vertical velocity

...

Note
PLEASE NOTE: Multi levels data are only available at 3-hourly intervals.

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.

title	UV Index definition and computation

CAMS provides a global solar UV index forecast (from the ADS), conforming to the WHO definition.

UV Index data is available as:

To generate this data, we compute the surface down-welling spectral solar irradiance in the range 280-340nm at 5nm resolution taking into account local surface albedo, aerosol, clouds and ozone in the model profile. This is then convoluted with the erythema spectrum, resulting in the biologically active UV radiation. For more details please have a look here.

UV Index plots are available showing:

corresponding to the two UV index parameters described above. To create the plots we divide the UV biologically effective dose rate by 0.025 W/m2 (i.e. multiplied by 40), resulting in the dimensionless UV index where one unit of measurement (ie the difference between UV Index X and X+1) represents 25mW/m2 of UVA and UVB radiation absorbed by the human skin.

UV Index values are instantaneous, not cumulated.

title	Web charts of biomass-burning AOD

The actual aerosol species represented in the model are defined more according to their chemical composition (e.g. sulphate, black carbon, organic matter) rather than their source type (e.g. biomass burning or fossil fuels).

What is presented on the web charts as "biomass-burning AOD" is the sum of organic matter AOD (omaod550) and black carbon AOD (bcaod550). Organic matter is almost always the dominant component out of these.

Historically, biomass-burning was the main source of such aerosols in the model, apart from a much lower background of primary OM+BC from fossil fuels and of OM from biogenic secondary organic aerosol (SOA).

However, since a representation of anthropogenic SOA as a source of OM was added (in cycle 43r1, implemented in January 2017), the model also captures the relatively high levels of this OM around polluted cities.

To sum up, if you want the data used for those web charts, take omaod550+bcaod550 (which will usually be fairly close to omaod550 alone). However, note that this will also show significant aerosol plumes from anthropogenic pollution as well as biomass burning.

Issue type	Description	Cycle
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
