It is an acknowledged fact and also a common experience that the accuracy of weather prediction has increased substantially in the last two decades or so. This can be attributed to a large extent to the continuous upgradation of the capabilities of weather satellites. India has always been at the forefront in this area and currently it has two very sophisticated state-of-art INSAT-3D satellites that provide half-hourly images of the weather, and a variety of data like vertical profiles of temperature, cloud motion winds and sea surface temperature.The purpose of this book is to explain the science behind the weather satellites, the constraints of technology, and the wide possibilities of application. That too in a simple way that would make it interesting to readers whether they are well-versed with meteorology or not.
