CIRES/ NOAA GSD Atmospheric Chemistry and Aerosol Modeler

The Cooperative Institute for Research in Environmental Sciences (CIRES) in Boulder, Colorado and the NOAA Global Systems Division (GSD) have an immediate opening for a Professional Research Assistant or a Research Associate with experience in numerical weather prediction and/or air quality modeling to develop and support state-of-the-art coupled meteorology-chemistry models. The scientist will have an appointment within the Model Development Branch (MDB) of the ESRL Global Systems Division.


MDB has been leading the development of several coupled meteorology-chemistry models for many years. One of these models – Weather Research Forecasting coupled with Chemistry (WRF-Chem) is a widely used regional air quality model around the world ( The coupled meteorology-chemistry models developed at ESRL/GSD allow simulating complex aerosol-meteorology interactions on regional and global scales. In recent years MDB in collaboration with other groups at NOAA, EPA, and NASA has been leading the development of a new air quality forecasting model based on Finite Volume Cubed Sphere dynamical core (FV3), which is selected for the new operational weather forecast modeling system by NOAA/NCEP.


Implement new gas, aerosol and other atmospheric chemistry parameterizations in FV3-Chem and WRF-Chem models.

Assist with coupling new modules via the Common Community Physics Package (CCPP) and testing of new code developments.

Evaluate the models using atmospheric data from in-situ and remote sensing observations.

Assist with community support, participate in developer meetings, teleconferences and contribute to project reports.
