JURASSIC

Features

• JURASSIC uses the emissivity growth approximation (EGA) to conduct the radiative transfer calculations. Band transmittances are obtained from pre-calculated look-up tables from line-by-line calculations.
• The model was carefully tested in intercomparisons with the Karlsruhe Optimized and Precise Radiative Transfer Algorithm (KOPRA), the Reference Forward Model (RFM), and the Stand-alone AIRS Radiative Transfer Algorithm (SARTA).
• JURASSIC features an MPI-OpenMP hybrid parallelization for efficient use on HPC systems.

Getting started

Information for new users and developers is available from the JURASSIC GitHub repository.
