Research Skills

Dr. Matsui is the principle architect of the Goddard Satellite Data Simulation Unit (SDSU) and the Colorado State University Unified Land Model (CSU ULM). He also has experiences of mesoscale atmospheric models (WRF, RAMS, MM5), radiative transfer codes (Goddard radiation, Fu-Liou radiation), multi-sensor clod-precipitation retrieval using the TRMM satellite, and analysis of aerosol-cloud interactions.

Goddard SDSU is an end-to-end multi satellite simulator unit, which includes six simulators at present: a passive microwave simulator, a radar simulator, a spectrum visible-infrared simulator, a Lidar simulator, an ISCCP-like simulator, and a broadband simulator. SDSU can be used for radiance-based evaluation of cumulus ensemble models, supporting radiance-based data assimilation, and providing satellites radiances as priori database for physically based satellite retrievals. In this way, Goddard SDSU can bridge NASA’s modeling activity and NASA multi-platform satellite missions, such as TRMM, A-Train, GPM, and ACE. Goddard SDSU also supports JAXA-ESA EarthCARE satellite mission through a core of Japanese EarthCARE simulator.

CSU ULM is a unified large-scale surface hydrology model developed upon the NCAR CLM. CSU ULM has detailed sun-shade canopy and physiological processes, and soil-vegetation-atmosphere-transfer parameters can be initialized and optimized by NASA EOS satellite observations within the GSFC Land Information System.

Research Focus

My research focuses on the Earth’s energy and water cycle in the context of cloud-precipitation processes, aerosol-cloud interactions, and land-atmosphere interactions by application of satellite remote sensing (radiative transfer) and numerical models (microphysics, radiation, land process). Recent focus is the development of multi-scale cumulus ensemble model with high-resolution satellite radiance observations and multi-frequency satellite simulators.
