Modifications to STILT

  • Uncertainties in vertical mixing propagated

    • Approach similar to Lin and Gerbig ’05
    • Uncertainties comparable to uncertainties due to wind errors
    • Paper in prep.


Modifications to STILT

  • VPRM preprocessor

    • input: configuration file “namelist”
      • Grid specifications (projection, limits)
      • Time frame
    • output:
      • EVI, LSWI & Vegetation map at desired resolution for one year (min)
      • netcdf format
    • Uses: Modis reflectances MOD09A1 from local database
      • Tool tells what tiles are required for downloading


Modifications to STILT

  • Coupling hourly emission fluxes within Trajecvprm()

  • EDGAR emission converter

    • get.edgar() to create hourly fluxes at desired resolution (needs upgrade to create ncdf files)


STILT plans at Jena

  • coupling to TM3 global model as Boundary Condition

    • TM3 runs using fluxes from inversions, coupled to Biome BGC
    • Check if nesting improves in forward runs
  • Nested inversions coupling STILT + TM3 adjoint

    • European nest for high resolution (~ 20 km) (Kristina Trusilova)
    • Tall tower data plus global network as input
  • STILT-WRF-VPRM for mesoscale inversions

    • At specific tall tower locations in Europe + aircraft data CERES


Future: keeping STILT stable

  • Keeping STILT stable throughout development phases

    • Method: set of hymodelc test runs with a result control facility
  • How (suggestion):

    • @ Harvard Grid computer
    • each group provides a (set of) test runs with all required inputs
    • SK provides a fuzzy checker tool to compare PARTICLE.DATs as core of semi-automated verification (random off, can only check when results are not supposed to change)
    • developer should run one batch file only which is part of the STILT CVS repository itself
    • it takes f90 files from user (scp to local machine) and compiles, runs and compares on GRID
