HIRLAM Chemical branch & Enviro-HIRLAM online integrated NWP-ACTM model

This site introduces the HIRLAM Chemical branch, organised according to the decision of HIRLAM-A and ACTM teams of the HIRLAM consortium (see some documentation attached below), and the Enviro-HIRLAM online integrated NWP-ACTM model, considered as a baseline system for the HIRLAM Chemical branch.

The strategy of integration of the HIRLAM NWP and ACTM within the HIRLAM consortium is described in HIRLAM newsletter, 53 (Baklanov, 2008) and the current version of the Enviro-HIRLAM model - in HIRLAM newsletter, 54 (Korsholm et al., 2008).

The Enviro-HIRLAM 10-years development history:

• 1999: Started at DMI as an unfunded initiative

• Used previous experience of Novosibirsk scientific school and SMHI (A. Ekman PhD)

• 2001: Online passive multi-tracer pollutant transport and deposition in HIRLAM-Tracer (Chenevez, Baklanov, Sørensen)

• 2003: Aerosol and chemistry model tested first as 0D module in offline CAC (Gross, Baklanov)

• 2004: Test of different formulations for advection of tracers incl. cloud water (K.Lindberg)

• 2005: Urbanisation of the model (funded by FP5 FUMAPEX) (Baklanov, Mahura, Peterson)

• 2005: COGCI grant for PhD study of aerosol feedbacks in Enviro-HIRLAM (Korsholm)

• 2006: Test of CISL scheme in Enviro-HIRLAM (Lauritzen, Lindberg)

• 2007: First version of Enviro-HIRLAM for pollen studies (Mahura, Korsholm, Baklanov, Rasmussen)

• 2008: New economical chemical solver NWP-Chem (Gross)

• 2008: First version of Enviro-HIRLAM with indirect aerosol feedbacks (U.Korsholm PhD)

• 2008: Testing new advection schemes in Enviro-HIRLAM (UC: E. Kaas, A.Christensen, B.Sørensen, J.R.Nielsen)

• 2008: Decision to build HIRLAM Chemical Branch (HCB) with Enviro-HIRLAM as baseline system, Enviro-HIRLAM becomes an international project

• 2009: Integrated version of Enviro-HIRLAM based on reference version 7.2 and HCB start (currently there are several versions of the model code)
