JANUS (1D convective atmosphere model)

Generates a temperature profile using the generalised moist pseudoadiabat and a prescribed stratosphere. Calculates radiative fluxes using SOCRATES.

Pronounced jan-us. Jan as in "january", and us as in the collective pronoun.

Developer installation instructions

1. Download and install Socrates

git clone git@github.com:nichollsh/SOCRATES.git
cd SOCRATES
./configure
./build-code
source set_rad_env
cd ..

2. Download and install Janus

git clone git@github.com:FormingWorlds/JANUS.git
cd JANUS
pip install -e .

3. Download data from the OSF repository
   • Set the environment variable FWL_DATA to define where the spectral data files will be stored
     • export FWL_DATA=...
   • Run the following commands to download all basic data
     • janus download spectral
     • janus download stellar
   • Alternatively, you can specify which spectral data you want to download, and optionally the number of bands
     • janus download spectral -n Frostflow -b 4096

Run instructions

In the examples folder you can find python scripts showing typical usecases/workflows of atmosphere modelling with Janus.
