MEMORANDUM FOR: Distribution E
FROM: John H. Ward
Chief, Production Management Branch
SUBJECT: Changes to the NWS Production Suite
On Tuesday, 20 April 2004, the configuration of the Eta Model
will be modified to allow for the 0 - 84 hour forecast to run in the
current 0 - 60 hour time slot. This will be a permanent change.
The expected new delivery times for Eta products are as follows:
24 hr products: 5-10 minutes earlier
36 hr products: 15-20 minutes earlier
48 hr products: 15-20 minutes earlier
60 hr products: 20-25 minutes earlier
84 hr products: 35-40 minutes earlier
More precise times will be provided when they become available.
Details on the change can be found at:
http://www.nws.noaa.gov/om/notifications/tin04-07eta_compression.txt
Currently, on both the NCEP and TOC FTP servers, over 50% of
the gridded NCEP model data sets are not being accessed. A review
of file access on both FTP servers was conducted during the months
of January and February 2004. From this review a list of the
unaccessed data sets has been generated. It is NCEP's intention to
remove these data sets, but we would like to first solicit feedback
from our users. The proposed list of data sets to be removed has
been posted on the NCEP web site at the following location:
http://www.nco.ncep.noaa.gov/pmb/products/ftp_removal_list.html
An E-mail address has been provided on this page to allow for
users to provide feedback. Data sets were only included on this
list if they were unused on both the TOC and NCEP servers. User
comments on this list will be accepted through 15 June 2004. On 29
June 2004 all files deemed unnecessary will be removed from the NCEP
ftp server. This process will provide the additional server
resources to host higher temporal and spatial resolution data not
currently available.
