NOAA Satellite Operations Facility HRIT/EMWIN VSAT Antennas In December of 2017, the first of the new GOES-R Series of satellites “GOES-16” became the operational East satellite after its launch the previous year. GOES-17 was then launched on March 1, 2018 as the follow-up to obtain GOES-15’s west position. The HRIT/EMWIN service on the Geostationary Operational Environmental R-series Satellites (GOES-R) has undergone several product transitions over the period from December 2017 through January 2019. The deactivation of the GOES-15 LRIT broadcast, all three GOES N-P series satellites (GOES-13, GOES-14 and GOES-15) LRIT transponders are inactive, but can be activated in the need of contingency. To find out more information regarding GOES T and U future launches and status, please visit the GOES-R Launch and Orbit page located on the GOES-R website. NESDIS provides “GOES Flyout Charts”. The fly-out charts provides information regarding each GOES mission life and expectancy for operations.

GOES-16 Longwave Infrared Band 13 Full Disk Imagery While GOES-13/14/15 carried the GOES Imager having 5 bands of imagery, GOES-R Series carries the Advanced Baseline Imagery (ABI) which has 16 imagery bands. The baseline spatial resolution varies from 0.5 Km in the visible Band 2 to visible Band 1, near-IR Band 3 and near-IR Band 4 at 1 Km with the remaining bands having spatial resolution at 2 Km. For more information see GOES-R “Cloud and Moisture Imagery Fact Sheet” or the GOES-R “ABI Bands Quick Information Guides. This is a significant increase in quality and in quantity of imagery. Of the 16 ABI bands, 7 bands in the full disk sector have been selected for broadcast on HRIT/EMWIN. HRIT also includes 3 bands in the mesoscale sector. Details of the imagery can be seen in the NOAA GOES-East / GOES-16 HRIT/EMWIN Content Table.

2010 NOAA Satellite Conference Receive Terminal Example HRIT/EMWIN also went through a transition with the National Weather Service’s (NWS) Emergency Manager’s Weather Information Network or EMWIN broadcast. Like LRIT, EMWIN had its own transponder and broadcast on GOES-13/14/15 with a center frequency of 1692.7 MHz. The satellite broadcast of EMWIN is now one component of HRIT/EMWIN. The EMWIN virtual channels 20-22 carry a large array of NWS produced warnings, watches, forecasts, discussions and graphic imagery products. Also included are other emergency information; for example, amber alerts. The EMWIN products are now sent as individual messages where on the legacy LRIT broadcast, they were sent as a serial stream in QBT “block” format. The serial stream on GOES-15 will end when the new NWS Integrated Dissemination Project becomes operational in May of 2019 with the deactivation of the legacy 1692.7 MHz EMWIN broadcast during the same time-frame. Commercial software packages are available to present the EMWIN information on a CRT as a series of windows.

GOES DCS End-To-End Overview The GOES Data Collection System (DCS) information is a data relay system used to transmit observations from surface based environmental platforms through NOAA's geostationary satellites, for delivery back to the platform owner. Government agencies (U.S. federal, state, local, and international) anywhere in the footprint of GOES of which users can apply to utilize the system. Users are given frequency and time slots for their transmissions. The GOES DCS is the critical communication tool for near real-time observations for almost every network in Continental US and neighboring countries. There are thousands of Data Collection Platforms that transfer their observations through GOES satellites. Some examples are automatic weather stations, tide and tsunami buoys, river and flood gauges and seismic gauges. There are several ways to access or receive GOES DCS data. One way is through HRIT/EMWIN with alternative of DOMSAT. GOES DCS observations, while in text, are coded and requires each DCS user of HRIT/EMWIN to have the proper application to store these files in a database and to decode them if necessary. Each owner of a Data Collection Platforms (DCP) is the owner of the observation from those platforms.

2018 National Hurricane Center North Atlantic Tracking Chart Another product component is a selection of tropical weather and ocean graphics that are pulled from the NWS National Hurricane Center. These include tropical storm tracks, maritime forecasts, maritime surface charts and discussions along with winds and seas warnings.

Himawari Infrared Imagery Also included in the HRIT/EMWIN broadcasts are graphic versions of Japan Meteorological Agency (JMA) Himawari and EUMETSAT Meteosat Second Generation Seviri data. NOAA receives Himawari visible, Infrared and Water Vapor images from the Japanese Meteorological Agency and converts them to NOAA HRIT format. Both imagery datasets are transmitted each hour over the broadcasts. Himawari carries the HBI or Himawari Baseline Imager instrument which is very similar to the GOES-R ABI. Thus, the full disk images are nearly compatible with the ABI images that are closest in wavelength and in the case of GOES-West, offer a view of the Pacific area from Asia to much of North America.

Also, note that the native format of the imagery from the GOES-R Series of satellites is the Network Common Data Form – Version 4, or netCDF4. This format is transposed into the HRIT/LRIT format for inclusion into the HRIT/EMWIN broadcast and a can be explanation found on netCDF and netCDF4 as well as on The “Coordination Group for Meteorological Satellites LRIT/HRIT Global Specification”. On HRIT/EMWIN, the products are arranged into Product Groups and then virtual sub-channels. The HRIT/EMWIN Virtual Channel Identification (VCID) table 2.2 on this page and repeated under the Reception Tab provides a mapping of the products to the Virtual Channel IDs with the product delivery periodicity, satellite availability and format. There is also a link to the home web page of the product. More information on the HRIT/EMWIN broadcast and broadcast reception can be found under their tabs on this site.
