COSMO-SPECS: a spectrally-resolved cloud microphysics framework coupled to the weather model COSMO

Intro

COSMO-SPECS is a spectrally-resolved cloud microphysics framework developed in the TROPOS modeling department.

Release Information

title: COSMO-SPECS Release v0.9.1: Idealized Flare Version

tag: v0.9.1_flare

• Developments

  • parcel driver was reimplemented PR #107

    • implementations that belong to the SPECS PARCEL model (see https://gitea.tropos.de/COSMO-SPECS-Team/SPECS_Parcel_Model) were ported back to the SPECS main code
    • parcel-related routines are stored under LM/PARCEL/
    • parcel driver interfaces to SPECS cloud microphysical routines, but still has its own aerosol particle descriptions

  • a simple flare implementation (INP-based perturbation) was added PR #105

    • an additional INP source can be switched on in a certain place for a certain time period
    • a new namelist was added &FLARE_SBM with modifiable parameters with respect to source strength, location, height, timing and activation temperature

  • the selection of dedicated variable groups for 3D output was implemented PR #108

• Testing
  • testcases were significantly improved (PRs #102, #104, #112)
    • revised:
      • CyCare test was revised such that it now runs at DKRZ levante and at TROPOS servers
    • new:
      • Eriswill test was implemented with a flexible domain size of 12x12, 42x32 and 122x112 grid cells
      • a parcel test was implemented that runs idealized parcel ascends
      • the dev_test_CS for test automation was added which can be used for automated testing (mainly integration tests with compilation and execution)

Special Credits to Jens and Willi for their major contributions.
