Lead Research Scientist

SSAI - Greenbelt, MD

August 2012 - Present

Supports NASA GMAO scientific research program on seasonal-to-decadal climate prediction using coupled ocean-atmosphere-sea ice-land-surface models.

• Maintains the coupled ocean-atmosphere-sea ice analysis system, runs routine (monthly) ocean and sea ice data assimilation global analysis to produce the initial conditions for the seasonal forecast. Creates and maintains pre- and post- processing scripts, in particular, computes the statistics of the data assimilation system performance, generates graphics for the ocean climate web page and prepares output for the collaborative projects, including GODAE OceanView framework and NCEP CPC Real Time Multiple Ocean Reanalysis Intercomparison.
• Participates in testing and analyzing the new ocean analysis system, isolating and defining its problems and deficiencies, such as build-up of excessive sea ice thickness or incorrect local river runoff.
• Tests and analyzes the impact of the new types of satellite observations. Recently the effects of including the ocean color data into the ocean data assimilation systems were assessed. The results of the experiments on assimilation of the chlorophyll concentration demonstrated the improvement of the sea surface temperature and upper ocean heat content analysis skill.
• Supervised the long term (50 years) coupled ocean-atmosphere-sea ice integrated ocean data assimilation system (iODAS) experiment, assimilating ocean and sea ice in-situ and satellite observations using multivariate using ensemble optimal interpolation (EnOI) method, providing initial conditions for the decadal hindcasts.
• Studied the newly available remote Aquarius sea surface salinity (SSS) data, assessed its potential usability for oceanographic data assimilation; collaborated with the data production team on using GEOS-5 model to calibrate and validate the data.
• Evaluated sea surface height (SSH) long-term trend based on the analyses and hindcasts, including attribution of its variability to the various components of the water volume balance in the ocean.
• Produces visualizations, presentations and manuscripts based on the results of the scientific investigations.

Supported NOAA/NWS/NCEP Climate Prediction Center research effort to improve the prediction and monitoring activities.

• Investigated various ensemble forecast schemes for seasonal prediction.
• Investigated seasonal predictability based on the ensemble characteristics.
• Run R2 atmosphere and MOM4 ocean assimilation and model scripts for data denial experiments, evaluates various metrics of the assimilation skill in relation to the data availability and model variability.
• Conducted the CFSR assessment and validation study using the independent data from the OCS, comparing the reanalysis heat fluxes with the COARE-corrected fluxes with the in-situ fluxes at the KEO mooring location.
• Analyzed and prepared data as required for the reanalysis research studies.
