The JCSDA is pleased to present the first public, open-source release of the Joint Effort for Data assimilation Integration (JEDI) system, JEDI-FV3 1.0.0. The JCSDA is also excited to announce release 2.4.0 of the Community Radiative Transfer Model (CRTM).

The JEDI-FV3 1.0.0 release contains everything needed to emulate at low cost the JCSDA near-real-time applications websites with JEDI-GFS and JEDI-GEOS. This includes interfaces for processing a wide variety of observational data and a library of observation operators for conventional, satellite radiance and GNSS-RO measurements that can be run from both FV3-based UFS/GFS and GEOS models.

To access the JEDI-FV3 code, detailed release notes, self-paced tutorials and more, please visit the JEDI-FV3 Release page.

The CRTM 2.4.0 release offers a number of substantial improvements over the preceding release 2.3.0, but nevertheless ensures backwards-compatibility for long-term and operational users.

New features include:

Shared-memory OpenMP parallelization
NetCDF4 interfaces for Cloud- and Aerosol coefficients
The pyCRTM interface
Github integration, ecbuild build system, and unit test environment
