COSIPY-FecMo: A coupled glacier surface SEB + SMB and glacier subsurface firn elevation change model

License: Reuse only with reference to the creators.
The dry_densification scheme is based on Herron and Langway (1980)[1], you find the PDF e.g. on cambridge.org.
The fdm is written in python 3 and tested with Anaconda3 on the Python 3.6.3 Shell on Windows10 and Ubuntu 16.04 LTS. THE MODEL IST IN DEVELOPMENT.
Set debug_level in config.py.
Which level should be saved to logfile?
| Level | Numeric value | Behaviour |
|---|---|---|
| CRITICAL | 50 | Crash info |
| ERROR | **40 ** | Still running but erroneus results |
| WARNING | 30 | Potentially harmful processing |
| INFO | 20 | Coarse-grained info (excluding variables) |
| DEBUG | 10 | Fine-grained info (including variables and levels 10-50) |
| NOTSET | 0 | No logging |
