This book provides a thorough introductory description of the physical
principles underlying the satellite remote sensing of clouds and
precipitation. A diverse collection of satellite sensors is covered,
including imagers, radars, and sounders over a broad spectral range from
visible to microwave radiation.
The progress in satellite instrument technology during the past two
decades as represented by the Tropical Rainfall Measuring Mission
(TRMM), CloudSat, and Global Measurement Mission (GPM) satellites has
drastically improved our capability of measuring clouds and
precipitation across the globe. At the same time, such rapid progress
makes it increasingly challenging for scientists without specialized
skills in remote sensing to fully grasp how satellite measurements are
being made. This book is designed to mitigate that challenge. The
targeted readers are graduate students and professional scientists
seeking an extended summary of the theoretical background behind
observations from space, ranging from fundamental physics (the
statistical mechanics and radiative processes, for instance) to more
practical levels of theory such as retrieval algorithm design.
