Atmospheric Satellite Observations: Variation Assimilation and Quality Assurance provides a useful reference to satellite data assimilation. Drawing from her 30+ years researching, supervising graduate students and teaching courses on atmospheric data assimilation, Dr Zou has written an easy to use, complete guide on satellite data assimilation. Organized in two sections, mathematical concepts and variational data assimilation, topics covered include linear algebra to aid in reading involved matrices, frequently used statistical methods, the interpolation role of function fitting, filtering when dealing with real observations, minimization as used in data assimilation systems, 3D-Var and the inverse problem it solves, the practical development of adjoint models and the 4D-Var method. It further reviews different systems specific coverage like GPS radio occultation (RO) and GOES Imagers. This book concludes by tying together everything covered and applying all concepts to the observation of hurricanes.
- Mathematical concepts from several branches of study, including calculus, linear algebra, probability theory, functional analysis and minimization are reviewed as needed
- Illustrates Quality Assurance for satellite observations using real data examples
- Dedicated chapter on how all reviewed concepts within the book apply to hurricanes
- Reviews theory, system development, and numerical experiments of 3-dimensional and 4-dimensional variational data assimilation (3D-Var/4D-Var)

Dr. Zou's research interest is in atmospheric data assimilation. She developed a full-physics 4D variational data assimilation (4D-Var) system for the NCEP, a full-physics regional 4D-Var system for the PSU/NCAR mesoscale model, and another regional 4D-Var system for the Coupled Ocean/Atmosphere Mesoscale Prediction System. She pioneered and conducted research in the variational assimilation and quality assurance of space-based Global Positioning System radio occultation, multi- 7 sensor surface rainfall, Total Ozone Mapping Spectrometer ozone, ground-based GPS total precipitable water and zenith angle, radiances from three types of microwave instruments (imagers, temperature and humidity sounders), and hyperspectral cross-track infrared sounders onboard polar-orbiting satellites and geostationary satellite imagers, as well as airborne Doppler radar data for hurricanes. Dr. Zou published over 172 papers in refereed scientific journals and this is her first book. She has been a Fellow of the American Meteorological Society since 2008
