  1. documentation on ALARO • Description of namelist variables and their meaning/tuning • Content • very basic information on scheme • description of namelist switches and parameters NAMPHY, NAMPHY0, NAMPHY1,NAMPHY2, NAMGFL and if needed some others • short notes on possibilities and combinations which are available • default/proposed settings • comment if it is tunable or have given value, if it is sensitive on resolution change • reference where to find more information • ... • basis is cy36; note if something is changed in cy37 or cy38

  2. documentation on ALARO Turbulence - Louis - pTKE - „moist gustiness“ - TOUCANS - mixing length Radiation - NER statistical model - Voigt effect - inversion detection (acnebn) - saturation cloud model - ozon profile - aerosol Large scale condensation scheme - Xu Randall / Smith / Rash-Kristjansen scheme Microphysics - PDF based sedimentation - fall speed - WBF process - cloud geometry - graupel - autoconversion, collection, evaporation and melting processes (alaro and arpege type)

  3. documentation on ALARO GWD - (orographic influence) - drag - mountain lift - rotation around mountain Diagnostics - Screening level diagnostics - Roughness length - Drag coefficient - Gust diagnostics - Charnock’s formula Deep convection - updraft - downdraft - convective cloud cover - closure assumption - Entrainment - CA Shallow convection - current one - new inside TOUCANS Cloudiness - near maximum overlap

  4. LACE plan 2012/13 • D1:TurbulenceschemeTOUCANS: • Readyforoperationaluse • Theoreticalandtechnicaldocumentations,scientificpublications • D2:Improvementsintheradiationscheme: • Readyforoperationaluse • Adaptationstoimprovealsoclimatesimulations • D3:Cloudscheme: • Finishanalysisofharmonization(unificationofcloudiness). • Coding,makefirsttests.

  5. LACE plan 2012/13 • D4:1D-2Dextensionofturbulence(cont.in2013) • Evaluation • D5:3MTinhighresolution • implementationandvalidation • operationaluse(2013) • D6:SURFEXinALARO(cont.in2013) • validations,readyforoperationaluse

  6. LACE scientific strategy 2013-18 • to deliver NWP research and provide scientific innovations for 5-2km mesh, for the next generation of operative models • a set of scale adoptive physical parameterizations • various operational resolutions of the model • the best price/quality ratio • operational model at 2km.
