Quickstart

Example of a JURASSIC simulation

JURASSIC provides a project directory for testing the examples and also to store other experiments:

cd jurassic/projects

This shows how to run the example for the nadir sounder:

cd nadir ./run.sh

This shows how to run the example for the limb sounder:

cd ../limb ./run.sh

In both examples, we generate an observation geometry file,

cat obs.tab

a standard atmosphere for mid-latitudes,

cat atm.tab

and conduct radiative transfer calculations for two or three detector channels:

cat rad.tab

The output of the simulation is verified by comparing it to reference data. Additionally, gnuplot is used to create plots of the radiance and kernel data.

Further information

More detailed information for new users and developers is provided in the JURASSIC user manual and collected in the GitHub wiki.
