EMWIN Services Transition - 2016/2017 Webinar

The following data management message was posted today.

GOES-R, the next generation of NESDIS GOES satellites, is scheduled for launch in October 2016 and should become operational in by October 2017.  EMWIN data, NESDIS imagery and goes data collection system /DCS/ data will be transmitted together over the GOES-R HRIT/EMWIN transponder at 400kbps.  The increased bandwidth is expected to improve the throughput of the EMWIN data stream. The new service will require new receiver hardware as there will be a
receiver frequency shift to 1694.1 MHz, from 1692.7 MHz /EMWIN/ and 1691.0 /LRIT/ and a change in modulation for EMWIN users. A new antenna or antenna components may also be required.

The EMWIN data will be broadcast as complete files over the HRIT/EMWIN channel, which is a departure from the present EMWIN packet streaming format. The EMWIN file names will also change from the existing 12 character format, to a more lengthy WMO compliant format.  The EMWIN eight character files names currently in use will be included in the new file names, to assist current users with product identification.

The decision to place the GOES-R satellite at the east /75-degrees w/ or west /137-degrees w/ location has not yet been made.  A date for the decision has not been announced.

The NWS will be hosting and online webinar at 1400 EDT/ 1800 UTC, on April 14, 2016, to identify and review the upcoming changes to ENWUB services.  General registration for the webinar is available on the following links:
