Professor Zou Xiaolei from university of Maryland was invited by CUIT to give an academic lecture

On the morning of May 22, professor Zou Xiaolei from the university of Maryland gave an academic lecture entitled “GPS RO Bending Angle Data Assimilation Using a Limited-ray-path 2D Raytracing Operator and an Impact Multipath Detection Algorithm” in the 215 meteorological building at the invitation of the school of atmospheric sciences. The report was led by zhang yu, deputy dean of the school of atmospheric sciences at chengdu university of information technology. The faculty and students of the school of atmospheric sciences were actively involved.

Professor Zou first detailedly introduced the GPS RO data assimilation operator, COSMIC occultation observation principle, the improvement of cosm-2 and its scientific value in detail, then proposed a three-step quality control method, and verified its practical application value by testing the influence on deviation and standard deviation. Through data analysis, she pointed out that the accuracy of simulation and data assimilation could be maximized by integrating the ray equation over a limited ray path length (250-400km from perigee).

After the report, professor Zou had an in-depth discussion with the teachers and students about the development of meteorological satellites and the spatial and temporal resolution characteristics of COSMIC occultation data. Her teaching and scientific research style benefited the teachers and students.

Expert introduction:

Zou Xiaolei, born in 1960, is a professor at the multidisciplinary research center for earth system science at the university of Maryland. In July 1984, she graduated from nanjing meteorological university (now renamed nanjing university of information technology), and in August 1988, she received a doctor’s degree in meteorology from the institute of atmospheric physics, Chinese academy of sciences. Between 1989 and 1993, she developed the four-dimensional variational assimilation system of the NCEP global business model for medium-term numerical forecasting, and completed many original works of developing Fourier transform and discrete physical process adjoint operators in the global spectral model. From 1993 to 1997, the center for atmospheric research (NCAR) developed the regional numerical prediction research model (MM5), a four-dimensional variational assimilation system with a complete physical process, and led the research on the assimilation of GPS occultation data. She has long been engaged in the development of data assimilation theory and system and the application of satellite data in numerical prediction and meteorological research. Most of her research results have been published in 730 SCI academic papers (h-index =40).
