CAMX: meteorological input data

The 3D prognostic meteorological model MM5 is used to generate all necessary meteorological input files.

A version using WRF to generate meteo date is in preparation.

CAMX: meteorological input data

CAMx reads and writes several 3-D time resolved files that will require significant disk space. Therefore, these files are written as Fortran unformatted binary to minimize storage requirements.

In contrast to the usual CAMx input files written in the IEEE "big_endian", for AIRWARE the IEEE "little_endian" has to be used for compatibility reasons. A detailed description of the file formats required can be found in the CAMx User's Guide, Version 6.00 ,

Main input files

  • Height/Pressure File: The Fortran binary height/pressure input file contains three-dimensional gridded fields of layer interface heights and layer-average pressure.
  • Wind File: The Fortran binary wind file contains three-dimensional gridded fields of layer average horizontal (u and v) wind components.
  • Temperature File: The Fortran binary temperature file contains three-dimensional gridded fields of layer average temperature and two-dimensional gridded fields of surface temperature.
  • Water Vapor File: The Fortran binary water vapor file contains three-dimensional gridded fields of layer average water vapor concentration.
  • Cloud/Rain File: The Fortran binary cloud/rain file contains three-dimensional gridded fields of cloud parameters to be used for chemistry and wet/dry deposition calculations. Note that precipitation rate is not explicitly provided to the model; instead, it is internally calculated from the three precipitation water content forms provided on the cloud/rain file.
  • Vertical Diffusivity File: The Fortran binary vertical diffusivity file contains three-dimensional gridded fields of layerinterface vertical diffusivity (i.e., turbulent exchange or diffusion coefficients).
