A general computer model of the ionospheric behavior during a solar eclipse is briefly described. Solutions are generated for 15 ionospheric species during the solar eclipse of 12 November 1966. These solutions are for altitudes from 60 to 120 kilometers, and include both neutral and charged species. (Author).

Hurricane Janice first appeared as a disturbed area south of Cuba. The first seven missions flown into the storm occurred on October 5, before it had attained hurricane intensity, the last on October 9, just before the storm experienced a rapid acceleration and intensification. The structure of Hurricane Janice during the developing and mature stages is described in this report. Profiles, horizontal cross sections, and radar photograph composites are presented. Particular attention has been given to the radar structure because of the somewhat three-dimensional nature of the data.

Atmospheric Satellite Observations: Variation Assimilation and Quality Assurance provides an invaluable reference for satellite data assimilation. Topics covered include linear algebra, frequently used statistical methods, the interpolation role of function fitting, filtering when dealing with real observations, minimization in data assimilation systems, 3D-Var and the inverse problem it solves, 4D-Var and adjoint techniques, and much more. The book concludes with satellite observation of hurricanes. - Contains mathematical concepts from several branches of study, including calculus, linear algebra, probability theory, functional analysis, and minimization - Illustrates quality assurance for satellite observations using real data examples - Includes a dedicated chapter on how different satellite instruments see hurricanes - Reviews theory, system development, and the numerical experiments of three- and four-dimensional variational data assimilation (3D-Var/4D-Var)
