Brief Bio

Dr. Takamichi Iguchi is an Assistant Research Scientist at ESSIC, UMCP. His primary research inrerests are cloud microphysics, regional weather and climate modeling, atmospheric aerosols, and remote sensing measurements. He is working on the development of atmospheric models using a detailed scheme for cloud microphysics, e.g., WRF coupling with spectral-bin cloud microphysics (WRF-SBM) and the model validation using observational data.
