NEW OPPORTUNITY (Fall 2022)

Data Assimilation of Satellite Precipitation: One Postdoc/PhD position is available at the Saint Anthony Falls Laboratory (SAFL) and the Department of Civil Environmental and Geo- Engineering at the University of Minnesota – Twin cities. The position will be funded by the NASA’s Precipitation Measurement Mission (PMM) program and needs to be focused on the state-of-the-art research and development on data assimilation of satellite precipitation into a coupled land-atmosphere model for improved forecasts of mesoscale convective systems. The project involves developing low-order models for precipitation moist processes through modern machine learning tools and expanding the previous research of the team on the Ensemble Riemannian Data Assimilation over the Wasserstein Space. Candidates with previous experiences, or a strong desire to learn, remote sensing hydrology, data assimilation, statistics, optimization, machine learning are encouraged to apply. The project will provide a unique opportunity to attend annual PMM science team meetings and exchange ideas with the science team members.   

The postdoc position will be available in February 2022. The PhD position is expected to start in Fall 2022. For consideration, please submit only your CV to Ardeshir Ebtehaj. The CV must include a list of at least 2 references.  

Update: This position is partially filled.
