    • Brief Bio

    Mohar Chattopadhyay is an Atmospheric scientist with experience in model development, data assimilation, large-scale climate data analysis and climate variability. She is an experienced numerical modeler with work experience in New Zealand, Australia and USA. Mohar has worked with numerous modeling systems including UKMO’s UM, MM5/WRF and Australian Bureau of Meteorology (BoM) models GASP/LAPS and ACCESS model and 4DVAR data assimilation systems. She also has experience in CSIRO's Cubic Conformal Model (CCAM).  More recently, Mohar has worked at NOAA/NESDIS/STAR/JCSDA on Cloudy Radiance assimilation and Microwave Intergrated Retrieval Systems (MiRS). She obtained doctorate degree in Atmospheric Physics from the University of Canterbury, Christchurch, New Zealand in 2003.
