Subject:  Corrected: Multi-Radar, Multi-Sensor System Products
Added to SBN and NOAAPORT Effective November 24, 2014

The unanticipated technical problems with a component of the SBN
software has been fixed and implemented. On or about Wednesday,
July 8, 2015, the NOAA AWIPS Program Office will add the Multi-
Radar, Multi-Sensor (MRMS) to the Satellite Broadcast Network

Once implemented, selected products from the MRMS System produced
by the National Centers for Environmental Prediction will be
added to the SBN and NOAAPORT. MRMS began operational production
of GRIB2 formatted products on September 29, 2014.

MRMS is a system with automated algorithms that quickly and
intelligently integrate data streams from multiple radars,
surface and upper air observations, lightning detection systems,
and satellite and forecast models. MRMS generates a high
resolution 3D radar mosaic and related 2D severe weather products
for NWP model data assimilation and aviation applications. MMRS
also produces a suite of quantitative precipitation estimation
products for the monitoring and warnings of floods and flash
floods and in support of comprehensive hydrologic and ecosystem
modeling. Numerous two-dimensional multiple-sensor products offer
assistance for hail, wind, tornado, quantitative precipitation
estimation forecasts, convection, icing, and turbulence
diagnosis. A product reference guide and training for users are
publicly available from the NWS Warning Decision Training Branch
website at:

Most MRMS products are generated on a 1km grid over the
Contiguous United States (CONUS) domain and updated as frequently
as every 2 minutes. Data volume will vary, depending on the
current meteorological conditions, but could be as high as 14GB
per day or 13MB every 2 minutes. Due to the large data volumes
this system generates, users who do not wish to receive MRMS
products are advised to filter out the applicable WMO headers
from their NOAAPORT feed.

WMO Headers and official WMO title for the new products are as

In addition to NOAAPORT dissemination, MRMS products can be
retrieved via Local Data Manager (LDM) directly from NCEP Central
Operations. To learn more about this dissemination path please
