<td colspan="20"><p>14. STATEMENT OF REQUIREMENT, PROBLEM, OR DEFICIENCY
OF EXISTING SYSTEM</p>
<p>Reference AWIPS RWP 30: “The high resolution of the hourly soundings
provides an excellent method to visualize the mesoscale detail with the
NWP models. Nearly all forecast situations benefit from meteorological
investigation of hourly model soundings through understanding to the low
level structure and model adjustment using in-situ data.” The Eta BUFR
Sounding Data have been a successful part of AWIPS via RWP 30. This RC
extends that capability to the GFS model. The AWIPS SREC evaluated this
requirement during OB4 and included GFS BUFR Sounding Data as a
candidate for OB5. Due to issues found during testing in the OB5
timeframe, the AWIPS SREC deferred this requirement to OB6.</p></td>
</tr>
<tr class="even">
<td colspan="20"><p>15. KNOWN OR PROPOSED SOLUTION</p>
<p>NCEP will generate the GFS BUFR soundings and disseminate these to
the TOC. The TOC will route these products to the NCF for further
dissemination to AWIPS. NCEP will create these products for the same
output locations as is currently done with the Eta model BUFR soundings,
as well as some additional output points for Pacific Region.</p>
<p>NCEP will encode each GFS model run’s soundings into BUFR and provide
them to the Gateway for dissemination to AWIPS via the following
pathway:</p>
<p>NCEP  NWS TG  AWIPS NCF  SBN(TG chan)  AWIPS &amp; NOAAPORT

<p>Units are hours from model initialization time.</p>
<p>3. The four GFS model run times are 00, 06, 12 &amp; 18 UTC.</p>
<p>4. Vertical resolution: Match Eta vertical resolution</p>
<p>5. Stations: All available GFS stations NCEP is currently making GFS
BUFR data at</p>
<p>6. Retention period: At least two GFS model runs.</p>
<p>7. AWIPS Display: In D2D in the Skew-T log P view, Regional and
States scale (RFC will see sounding from RFC scale)</p>
<p>8. Data Volume: This parameter will contribute 240 MBytes on a daily
basis</p>
<p>The NWS TG shall provide these products in very-near-real time to the
AWIPS NCF for uplink on the SBN’s TG channel.</p></td>
