Abstract
In reports and papers about climate services both the term ''portal" and ''platform" are used.In this paper, we use ''portal" mainly for digital information systems and interpret ''platform" as an exchange forum that includes experts and users in addition to digital information.We recognize that the terms are oftensometimes confusingly -used interchangeably, in a few cases adding ''web-based" or ''digital" to the term ''platform" to constrain the term to what we call ''portal" in this paper.
