A product tutorial on Sandwich Products was recently published on the EUMeTrain website. The aim of the tutorial is to help users (weather forecasters and/or other experts) to understand and use these composite images, by giving them the most relevant background information and examples.
A short (two-pages) Quick Guide on Sandwich Products is also available on the site. The present product tutorial provides a deeper inside into the topic by providing more detailed guidelines, physical background, benefits and limitations, plus several examples of the cloud top features which can be observed in sandwich images.
