JCSDA is pleased to announce the release of version 1.0.0 of the CRTM instrument coefficient generation package CRTM_coef v1.0.0.

The first expert-level release of CRTM_coef v1.0.0 occurred on July 1, 2021.

Every year, members of the JCSDA community and beyond look forward to the Technical Review Meeting and Science Workshop. The annual meeting gathers the JCSDA core team, partners, and the wider scientific community to share in cutting-edge science and updates related to JCSDA projects.

The 18th JCSDA Technical Review Meeting and Science Workshop was held virtually for the first time the week of June 7 - 11, 2021. According to numerous attendees, the virtual meeting was a success, with many already looking forward to next year’s meeting.

JCSDA is pleased to announce the release of version 1.1.0 of the JEDI-FV3 software package.

The first public release of JEDI-FV3 occurred in October 2020. The 1.1.0 release features a major update of the Interface for Observational Data Assimilation (IODA).

The Community Radiative Transfer Model (CRTM), developed at the Joint Center for Satellite Data Assimilation (JCSDA), is operationally used for remote sensing aerosol data assimilation.

The estimated distribution of atmospheric aerosols is primarily improved by assimilating aerosol retrieval products, with CRTM as a bridge between observational and modeling data. To further facilitate and enhance aerosol modeling, the CRTM team released a new model interface and sets of recently implemented aerosol coefficients since 2020.

A new major release of the Interface for Observation Data Access (IODA) will occur this month in concert with the next public Joint Effort for Data Assimilation Integration (JEDI) update.

In alignment with the JCSDA goal of collaborative development, the new developments of IODA (both release and post-release) have demonstrated its facility at enabling partner contributions.

Registration for the 6th bi-annual JEDI Academy is now open! The 6th JEDI Academy will be held virtually via Zoom June 21 - 25, 2021. Registration is limited to 50 applicants and will remain open until June 1, 2021.

On March 26, a dedicated internal release of the soca-science repository for the National Ocean and Atmospheric Administration (NOAA) Global Ocean Data Assimilation System (GODAS) was created.

The effort is the first application of a realistic, end to end, JEDI-based data assimilation (DA) system for a JCSDA partner agency — and a demonstration of the flexibility of the JEDI.

As announced in early March, the 18th JCSDA Technical Review Meeting and Science Workshop will be held virtually during the week of June 7 - 11, 2021.

Registration is now open with a registration deadline of May 17, 2021 for all prospective attendees.

On Thursday, March 18th at 1:00 pm MT, the DTC and JCSDA are jointly hosting a seminar presented by Shih-Wei Wei from the Atmospheric Science Research Center.

The Introduction to the Joint Effort for Data assimilation Integration (JEDI) AMS short course took place on March 10, 2021. Spanning only four hours, the short course was designed to be a condensed version of what one might learn on the first day of a typical JEDI Academy.
