Gregor Möller demonstrates comprehensively that tomography principle, as
commonly used in medicine for diagnostic purposes, can be well applied
to signals of the global navigation satellite system (GNSS). With the
newly defined approach, wet refractivity fields can be generated which
coincide with radiometer and radiosonde measurements significantly
better than operational weather models. This makes GNSS tomography
interesting for meteorological applications in particular, but also for
other disciplines, which relay on accurate modeling of the signal delay
in the lower atmosphere. The book assesses all relevant parts of GNSS
tomography, from electromagnetic wave propagation and GNSS signal
processing over tomography theory to specific test cases and
applications.
