browse graphicNational Weather Service Station Information System
National Weather Service (NWS) Station Information System (SIS) contains observing station metadata from November 2016 to present. These are renditions are used for daily updates to the Historical Observing Metadata Repository (HOMR). Within this dataset there are embedded PDFs which are loaded into Environmental Document Access and Display System (EDADS) Version 2 (EV2) in the Cooperative Station History library and the JSON formatted machine readable version of the information on the PDFs which are integrated into HOMR. The station updates contain station profile information, and changes in location, instrumentation, obstructions, observers, and observation times. NCEI only receives these files when something is changed on the station, or every 3 years for a NWS-mandated update. Version 2 of this dataset includes new equipment hierarchy and minor changes to how observer information is structured in the JSON interface files.
