The "enterprise Emergency Managers Weather Information Network" (eEMWIN) File Transfer Protocol (FTP) service is an anonymous FTP service operated by the United States (US) National Weather Service (NWS) National Centers for Environmental Prediction (NCEP) Central Operations (NCO). The files on the eEMWIN FTP service provide time segmented archived collections of weather, water and climate information which has been broadcast on the EMWIN segment of the National Environmental Satellite and Information Service (NESDIS) Geostationary Operational Environmental Satellite (GOES) East and West systems. The files on the FTP server are updated/overwritten at specified time intervals, and provide users the option of selecting the most appropriate range of file quantities and latency, ranging from 2 min to 3 hours. The files are in a compressed ZIP file format and contain either text or binary (image) formatted files.

Future Service Outlook

  • Enterprise EMWIN FTP Service Description
    • Anonymous FTP servers – account/registration is not required
    • Will provide separate GOES-N and GOES-R services to support the two different file naming conventions.
  • Status: In development
  • Implementation Date: On or about December 2016

The file names of the products stored in the Archive Files will be different due to the unique file naming conventions for the EMWIN GOES-N and the GOES-R broadcasts. The EMWIN GOES-R product file names in the Archive File will adhere to the following convention which is identical to the product file names received over the satellite broadcast. This convention is fully described in the NWS "EMWIN GOES-R Filename Convention" publication (PDF).
