MC-UNIK (Monte Carlo Modell)
Simulated device: pyranometer
Contact: Andreas Macke (firstname.lastname@example.org)
Radiation flux densities [W m-2], radiances [W m-2 str-1]
Minimum set of physical quantities:
- volume extinction coefficient [m-1]
- single scattering albedo [no dimension]
- particle effective radius [m]
- distinction ice, water, rain, snow (All 3D)
- Externally assumed: Shape of particle size distribution and shape of particles
Need for a special grid?
- cartesian grid required, adaption to triangular grid difficult
Are parameters given via namelist or have to be coded?
- no namelist, ASCII & binary input files
Are there special requirements to the input quantities?
- complete grid required, no gaps
Models for application: GESIMA
Suitable for MESSy?:
Format of input data: no specifications
Format of output data: ASCII
Computational costs: 1h for 1week, depending on size of 3d field
