The Service Records Retention System (SRRS) stores weather observations, summaries, forecasts, warnings, and advisories provided by the U.S. National Weather Service (NWS) for public use. SRSS products are legally mandated by Congress for archival at NCDC, and are retained for a five-year period. Customers often use SRRS records for accident investigations and litigations. Three broad categories of SRRS data exist: observations, forecasts, and graphics. Observations are typically text products while forecasts are both text and graphical. The graphics category of SRRS data contains images of surface analysis, standard layer upper air analyses, weather depictions, radar summaries, and ocean products. Coverage of these data is both global and regional. All categories of SRRS data are available through NCDC. SRRS graphic products are available for download through NOMADS.
