The abstract submission period is still open for the 102nd Annual Meeting of the American Meteorological Society in Houston, TX the week of January 23-27, 2022.

Since 2018, a group of Scientists and Engineers at the Mesoscale and Microscale Meteorology (MMM) Laboratory of the National Center for Atmospheric Research (NCAR) have been developing a global data assimilation (DA) system for the Model for Prediction Across Scales – Atmosphere (MPAS-A) within the software framework of the Joint Effort for Data assimilation Integration (JEDI).

Global JEDI-MPAS DA development is still underway as part of a US Air Force funded project named “PANDA-C” (Prediction AND Assimilation for Cloud) and in collaboration with JCSDA’s JEDI core team.

Dr. Wei Han is currently a UCAR/UCP/JCSDA employee and visiting scientist at the UW-SSEC focusing on GIIRS evaluation and JEDI.

He has developed a fast and accurate spectral shift estimation and correction algorithm and found the root cause of the GIIRS diurnal and seasonal spectral shift, which will be beneficial for future GeoHIS sensor development, data monitoring, and assimilation.

The Abstract Submission period is open for the 102nd Annual Meeting of the American Meteorological Society in Houston, TX January 23-27, 2022.

The 6th JEDI Academy, hosted virtually the week of June 21-25, was the latest in a series of training sessions for the Joint Effort for Data assimilation Integration (JEDI) users and community contributors.

This academy shifted focus toward observations, as it followed the most recent release of JEDI-FV3 on June 11, which featured major updates to the Interface for Observational Data Assimilation (IODA).

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.
