Gateway National Weather Service (NWS) Service Records and Retention System (SRRS)

The Service Records Retention System (SRRS) was developed to store weather observations, summaries, forecasts, warnings, and advisories provided by the U.S. National Weather Service (NWS) for public use, and are retained by the National Centers for Environmental Information (NCEI) [formerly the National Climatic Data Center (NCDC)].

Service products issued by the NWS offices are transmitted on the Advanced Weather Interactive Processing System (AWIPS) or Federal Aviation Administration (FAA) communications to an NWS Gateway (NWSTG) server. The products are then electronically transferred to the NCEI and ingested into the Hierarchal Data Storage System (HDSS) for records retention. The three basic groupings of NWS Service Products (SP) are:
1) Observations: reports originated by NWS, Federal Aviation Administration, or Department of Defense facilities and transmitted through the NWS Telecommunication Gateway, NOAAPORT, or equivalent. These reports include, but are not limited to, surface observations (including Automated Surface Observing System and Automated Weather Observing System reports), pilot reports, upper air reports, marine reports, and automated buoy observations;
2) Forecasts: all official routine and non-routine disseminated products related to, or derived from, NWS forecast and warning programs (alphanumeric and graphic format), regardless of dissemination method; and
3) Graphics: all routine and non-routine environmental data analysis graphics, such as surface analysis, standard layer upper air analyses, weather depiction, radar summary, etc.; and all routine and non-routine graphics represented as official NWS forecasts including aviation prognostic graphics (e.g., Low Level and High Level Significant Weather Prognosis) produced by the National Centers for Environmental Prediction and other NWS facilities (e.g., Alaska Aviation Weather Unit).
