BaLiFOp (BAckscatter-LIdar Forward-OPerator)
Simulated device: Calibrated backscatter-lidar (300-4000 nm) such as Ceilometers
Contact: Armin Geisinger (firstname.lastname@example.org)
Rayleigh and Mie scattering parameters, extinction and backscatter efficiency (molecules and particles), received signal (photon number, received power, range-corrected signal)
Minimum set of physical quantities:
- 1D: Profiles of:
- Number-size distribution of multiple parameter size-classes
Need for a special grid?
- Only vertical column required
Are parameters given via namelist or have to be coded?
- Standalone-Version: Set parameters during function call and read binary data. Included version: Using an interface to set parameters using a namelist
Are there special requirements to the input quantities?
Documentation:Under development for Version 1.0 of the operator
Models for application: COSMO-ART and (using a separate interface in the future) ICON-ART
Format of input data: NetCDF but can be adapted to other formats
Format of output data: NetCDF and for V 1.0 “feedback”-files
Computational costs: Calculation of a single profile: less than 1 second. Calculation of a time-series of profiles: less than 5 seconds (using vectorized and array-optimized IDL functions).
