Training module on Metop AVHRR RGB images

Training module on Metop AVHRR RGB images

Online, EUMeTrain

A training module on Metop AVHRR RGB images was published at the end of November 2017. The RGBs were tuned to create good quality Metop/AVHRR RGB images, as similar to the EUMETSAT recommended SEVIRI RGB schemes as possible.

Four RGB types (Natural, Cloud, Night and Day Microphysics RGBs) are discussed separately, according the following logical structure:

  • The aim of the RGB type
  • Physical background
  • How to create the given RGB type?
  • Typical colours
  • Examples of interpretations
  • Comparisons with the most similar standard SEVIRI RGB type
  • Exercises

 

After discussing the four RGB types separately the daytime RGBs are compared to each other, and the effect of the scanning geometry is also discussed.

The main aim of the training module is to help the users (weather forecasters and other experts) to understand and use these RGB types by giving them background information, examples and exercises.
