This section presents some hints in MARS terms on how to name the different products. This is meant as a guideline and shows the keywords that select a specific data set, but not all keywords necessary to retrieve the data. Usually, operational archive data can be identified with the following MARS directives:
class = od
domain = g
expver = 1
