This position is under the Joint Center for Satellite Data Assimilation (JCSDA) and provides scientific support for the enhancement of the Community Radiative Transfer Model (CRTM). This position is intended to improve and advance the radiative transfer modeling of infrared radiances that are affected by both solar and terrestrial radiation within the CRTM.
The CRTM represents the connection between the satellite radiance observations and the atmosphere. This connection is used to allow the satellite radiance observations to be incorporated into data assimilation systems and the information in these observations to be extracted and used for numerical weather prediction, aerosol and trace gas prediction and many other applications. The CRTM represents the cornerstone of the JCSDA and is used by many groups including NOAA/NESDIS, NASA/GMAO, NOAA/NCEP/EMC, U.S. Navy FNMOC, and others.
An initial focus of the work will be the characterization of surface-emissive and surface-reflective aspects of the radiative transfer problem, including the development of flexible definitions and models of surface reflectivity. Other key goals include implementing and validating non-local thermodynamic equilibrium (NLTE) effects within the radiative transfer algorithm of the CRTM and ensuring that solar effects are properly characterized. The project will eventually transition into infrared interactions with atmospheric constituents, such as gases, aerosols, clouds, and precipitation.
This position is under the Joint Center for Satellite Data Assimilation (JCSDA) and provides scientific support for the development of the Sea-ice Ocean Coupled Assimilation (SOCA) effort. This position is intended to advance the use of surface-sensitive microwave radiances in coupled ocean-atmosphere data assimilation. The work will be performed in the context of an operational-quality coupled assimilation system with applications in numerical weather prediction, sub-seasonal to seasonal prediction, and reanalysis. A key goal is to advance the use of microwave radiances in a manner that is physically consistent with the penetrating and emitting depth of the ocean-atmosphere interface layer. The work will be part of an effort to link all surface-sensitive radiances, regardless of spectral regime, in a manner that is physically consistent within the interface layer. It is also intended to serve as a step toward the analysis of salinity within the coupled data assimilation system.
This position(s) will focus on the continued development of the GFDL AM4 and fvGFS models at convection-resolving (< 4km) scales for nowcast to S2S scales and beyond. The qualified candidate(s) will have a strong background in the simulation of mesoscale and convective-scale features: examples include but are not limited to tropical convection, tropical cyclones, severe local storms, orographic and coastal phenomena, boundary-layer motions, or intense rain, wind, ice, or snow events.
The Joint Center for Satellite Data Assimilation (JCSDA) mission is to improve and accelerate the uses of research and operational satellite data in numerical weather and climate prediction models among its partner agencies - NASA, NOAA, and the DoD. The work is accomplished through well-defined joint projects, approved by the Management Oversight Board (MOB). Each project is managed by a subject matter expert, and is overseen by an Executive Team (ET) consisting of the Director, Associate Directors (one from each partner), and the Chief Administrative Officer (CAO).
The central role of the Executive Officer is to provide effective communication and coordination between the science Project Leads and the Executive Team (primarily through the Director and the CAO), to ensure that projects achieve their objectives effectively and on schedule, and with the ET sufficiently well-informed of the status of each project to provide guidance and assistance to keep them on track and to respond to new opportunities and challenges as appropriate. Another primary role of the Executive Officer is to provide effective coordination, communication, and organization between the JCSDA partner agencies at the level of the Executive Team, to ensure that best practices are used to plan, execute, and report, the activities of the JCSDA.
This position will be located in College Park, MD.

The long term objective of the Joint Effort for Data assimilation Integration (JEDI) is to provide a unified abstract data assimilation framework for research and operational use, for different components of the Earth system, and for different applications, with the objective of reducing or avoiding redundant work within the community and increasing efficiency of research and of the transition from development teams to operations.
In addition to the high level abstract code layer, the components of the current and future operational forecasting system, including the NGGPS dynamical core (FV3) and the operational data assimilation system (GSI) will be integrated into the new JEDI framework.
This position is under the Joint Center for Satellite Data Assimilation (JCSDA) and provides partial support for the Joint Effort for Data assimilation Integration (JEDI) project. This JEDI is an inter-agency plan aimed at developing a unified community Data Assimilation (DA) system for research and operations.
The core aspect of this position will be to define and implement a generic Interface for Observation Data Access (IODA) and the handling of observation-related data throughout the research and operational Earth system forecasting process, including data assimilation, observations pre-processing and use of observations for diagnostics.
The Joint Center for Satellite Data Assimilation (JCSDA) mission is to improve and accelerate the uses of research and operational satellite data in numerical weather prediction (NWP) models among its partner agencies - NASA, NOAA, and the DoD. Global Navigation Satellite System Radio Occultation (GNSSRO) atmospheric sounding sensors continue to become available to the NWP community, with comparatively large numbers of new sensors scheduled to be deployed on US government, international, and commercial platforms to provide sounding data that has been shown to complement and that obtained from scanning passive radiometric sounders.
GNSSRO provides quasi-vertical soundings of atmospheric properties related to pressure, temperature, and humidity that may be assimilated into numerical weather prediction (NWP) models as aggregate observables (radio refractivity or bending angles, etc.) The candidate who successfully fills this position will provide science support to verify and validate new-source GNSSRO observations, determine their error characteristics, develop and refine effective data quality control, and quantitatively test the impact of adding these data to NOAA’s operational NWP modeling systems.
This position is under the Joint Center for Satellite Data Assimilation (JCSDA) and provides partial support in a leadership role for the New and Improved Observations (NIO) project. The NIO project within the JCSDA is tasked with advancing the state-of-the-art research in satellite data assimilation. This overarching goal has multiple elements that interconnect the fields of environmental science, numerical weather prediction, and satellite remote sensing.
The NIO team is focused on two main objectives: ensuring Sensor Readiness to accelerate the assimilation of new satellite instruments and optimizing the use of existing satellite observations (e.g. all-sky and all-surface satellite radiance assimilation). Both of these goal sets include specific and direct collaboration with research scientists and JCSDA partners: NASA/GMAO, NOAA/NWS, NOAA/NESDIS, NOAA/OAR, the Naval Research Laboratory (NRL), Oceanographer of the Navy, and the US Air Force 557th Weather Wing.
We are seeking proposals that develop these principles in relation to one or other of the following two topics:
Proposals should focus on reviewing the current state of the art models and observations, evaluate how leading predictive models agree with in situ measurements and identify paths forward for addressing the key science and application gaps that need to be solved for improvements in models and predictions. This could include new and/or underutilized data sources that could be used to check predictive models, or identifying new methods for gathering in situ data that could be used to *drive* predictive models.
