Major modification in progress for this article - please DO NOT UPDATE THIS PAGE or your edits will get overwritten when the new modified article will be published. Please edit the working copy of this page in the C3S Modified CKB articles or CAMS Modified CKB articles section."

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.

...

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.

...

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.

...

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

...

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

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.

...

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	Visibility values are given in km rather than m	Visibility values are given in km rather than m however the GRIB and netCDF files indicate that the visibility values are in m. Hence they should be treated as km.	all versions
