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). |

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:
