Climate Services Information System

The Climate Services Information System (CSIS) is the principal GFCS mechanism through which information about climate – past, present and future – is archived, analyzed, modeled, exchanged and processed. The CSIS is the "operational core" of the GFCS. It produces and delivers authoritative climate information products through operational mechanisms, technical standards, communication and authentification. Its functions include climate analysis and monitoring, assessment and attribution, prediction (monthly, seasonal, decadal) and projection (centennial scale). New infrastructure will be added to the CSIS currently in place to fulfill the GFCS vision.
