- New model-error covariance matrices for aerosol and chemistry at 137 levels.
Observations
- TBC
Model
- Updated to use new CAMS_GLOB emissions inventory.
- Diurnal cycle for biomass-burning emissions updated to match that assumed within GFAS.
- Diurnal cycle for SOA production introduced to reduce night-time overestimation.
- New online dust emission scheme (Nabat et al., 2012).
- Sea-salt production over freshwater lakes eliminated.
- New nitrate and ammonium aerosol species, coupled to the gas-phase nitrogen chemistry. See new model parameters below
Sulfur species (SO2 and SO4) coupled between chemistry and aerosol schemes. See discontinued parameters below.
- Online calculation of dry deposition velocities for trace gases. (This was already in place for aerosols in 45r1.)
- Updates to wet deposition parameterisations. This brings greater distinction between scavenging by liquid and ice, and harmonises the treatment for aerosols and trace gases.
- Updates to chemical reaction rates.
- Updated to use new CAMS_GLOB emissions inventory.
