FLake is freely available under the
terms of the MIT license.
Download tar.gz file or zip file. These files contain
(i) routines of the lake model FLake,
(ii) routines of the atmospheric surface-layer parameterisation scheme
SfcFlx,
(iii) an example of FLake Interface for single-column applications.
A brief description of the source code is given in the synopsis of
FLake routines (click Documentation and download PDF file).
Test runs provide examples of the use of FLake in a stand-alone mode.
If you download the FLake code, please send the following information
to Arkady Terzhevik:
(i) your name,
(ii) your address,
(iii) your email address,
(iv) a few words to give an idea of how you are going to use FLake.
Arkady will then add you to the list of FLake users (this does not assume any obligations).
As a lake parameterisation module,
FLake is implemented into a number of NWP and climate models
(see menu item "Applications").
The source codes of those models are not necessarily freely available.
If you are interested in details of the implementation of FLake
into one or the other NWP or climate model,
please contact the code managers of the respective model.
The file consists of 6 columns divided by space characters with following values (See example files Potsdam80-96.dat, and Stechlin94-98.dat from Test Runs):
1 | 2 | 3 | 4 | 5 | 6 |
---|---|---|---|---|---|
Sequential number | Solar Radiation (W/m2) | Air Temperature (oC) | Air Humidity (mb) | Wind Speed (m/s) | Cloudiness (0-1) |
Put all 3 files in the same directory, open the directory in the Windows Explorer and type in the command line (press "Windows key"+R to call the command window):
flake < YOURFILE >,where < YOURFILE > is the name of Your namelist configuration file. The file with modeling results will be created after a successful model run.

If you use MATLAB for postprocessing and analysis of results the matlab-script ReadFlake.m can help importing data directly to MATLAB. Just run it from the matlab prompt.
