Introduction

As mentioned before in chapters 2 and 5, MSG WV channels are useful for locating PV anomalies or jet streaks and for deducing the general moisture distribution in the middle and upper layers of the troposphere. As a consequence both WV channels (6.2 and 7.3 µm) are also used to generate meteorological products and RGB composites. This chapter will present some of these VW based meteorological products and RGB combinations.
