Simulation period:

  • spin-up of 10 days from 22 Aug 2020 to 01 Sep 2020

Resolution:

  • horizontal grid spacing: 5km (R02B09) comprising 20971520 grid columns

  • number of vertical levels: 90

  • model time step: 40 sec

Comments:

  • no ocean model

  • land model JSBACH

  • plume model MACv2-SP with some modifications

Plume model MACv2-SP:

  • original version described in publication from Stevens et al.

  • coupling with graupel and radiation schemes:

    • dNovrN from plume model used to enhance background CDNC in graupel scheme (background CDNC of 80 cm-3)

    • dNovrN from plume model also used to enhance CDNC profile in radiation scheme (background CDNC of 80 cm-3 at surface)

    • change in CDNC in graupel scheme solely impacts autoconversion rate

  • modifications:

    • relationship of AOD and CDNC updated as described in Herbert et al.

    • biomass burning plumes (S America, C S Africa, Maritime Continent) adjusted so that anthropogenic component is 75 percent of total AOD

    • seasonal cycle removed and replaced with constant weights taken from mean during September

    • annual weights extended beyond 2017 and held at 2017 values
