FROM  RTH WASHINGTON DATA MANAGEMENT

Update #3:  Reminder that on Jan 7 the following McIDAS groups on
the SATEPSDIST5e server will become populated with data converted
from GRIB2 instead of GRIB1:  MOD/GFS... MOD/UKGL... MOD/NAM.  See
details provided in Update #1 regarding the differences in these
datasets as of Jan 7... and how to access test datasets.

Update #2:  Reminder that on Dec 10... in one week:
1.  NCEP will stop sending GRIB1 data to the DDS.  These are the
file patterns that will be affected:  
gdas1.tCCz.pgrbf?? and gfs.tCCz.pgrf??.  GRIB2 version of these
files are available.  Please contact the DDS Administrator if you
are not yet receiving the replacement products you need. 
2.  ESPC will also decommission the following McIDAS model groups
that are either no longer needed by NESDIS operations... or are no
longer being updated:  MOD/AWIP... MOD/EDAS... MOD/GESG...
MOD/ECG... MOD/NGM... MOD/RUC... MOD/MRFG.

Update #1:  GFS and NAM data generated from GRIB2 format input is
now available for testing.   The MOD/GFS and MOD/NAM can be
accessed with the following commands below:
DATALOC ADD MOD  140.90.213.191 ..to access data from test system... 
satepsdistb5e
DATALOC ADD MOD  140.90.213.160 ..to access current operational data
For users who want to process operational and test versions of the
data within the same session... the data are also served under
group name MODB on both servers.

For standard atmospheric parameters  U... V... P... T... RH... Z
etc  the difference between data from the operational and test
servers... if any... is expected to be insignificant.   For certain
surface parameters however the parameter names... levels... or
units for levels may be altered by the new processing... for
example: 
Precipitable water - name/level/units 
Ops:  PWAT/EATM/EATM   Test: PWAT/TRO/RSRV
Latent heat flux - name/level/units 
Ops: LHF/SFC /SFC            Test: LHET/SFC/

We are available to assist as necessary. 

Topic:  Upcoming Change to NCEP Model Data Distribution by ESPC

Date/Time Issued:  December 19... 2013   1452 UTC

Product/s/ or Data Impacted:  NCEP Model Data distributed by the
Data Distribution Server /DDS/ and SATEPDIST5e /McIDAS format/

Date/Time of Initial Impact:   December 10... 2013 1200 UTC

Date/Time of Expected End:  N/A

Length of Outage:  Permanent Change

Details/Specifics of Change:   

NCEP is in the process of decommissioning GRIB1 datasets.  As a
result... there are upcoming changes to the NCEP model data that
ESPC distributes.  This will be happening in two phases:  Dec 10...
2013... and Jan 7... 2014.

On Dec 10: 
1.  NCEP will stop sending GRIB1 data to the DDS.  These are the
file patterns that will be affected:  
gdas1.tCCz.pgrbf?? and gfs.tCCz.pgrf??.  GRIB2 version of these
files are available.  Please contact the DDS Administrator if you
are not yet receiving the replacement products you need. 
2.  ESPC will also decommission the following McIDAS model groups
that are either no longer needed by NESDIS operations... or are no
longer being updated:  MOD/AWIP... MOD/EDAS... MOD/GESG... MOD/ECG...
MOD/NGM... MOD/RUC... MOD/MRFG.

On Jan 7... the following McIDAS groups will become populated with
data converted from GRIB2 instead of GRIB1:  MOD/GFS... MOD/UKGL...
MOD/NAM.  Test data will be made available on Tue Nov 19... 2013 and
will be announced by a separate notification.
