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.

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 |
