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.

We are pleased to announce the 18th JCSDA Technical Review Meeting and Science Workshop will be held virtually during the week of June 7 - 11, 2021. The workshop was canceled last year due to COVID-19.

The annual JCSDA Technical Review Meeting and Science Workshop enables scientists partnering with JCSDA and the external research community to share the latest developments in satellite data assimilation, particularly as they relate to the status of JCSDA priorities and projects.

Registration for the Introduction to the Joint Effort for Data Assimilation Integration (JEDI) short course is now open.

The JCSDA hosted its 9th Symposium as part of the 101st Annual Meeting of the American Meteorological Society (AMS) January 9-15, 2021. The Annual Meeting was held as a completely virtual event as a result of the on-going COVID-19 pandemic. Despite the challenges presented by meeting completely online, the Meeting and the Symposium were successful.
