28SEP2006 FNMOC Ocean Analysis: New levels and more reliable delevery
In order to improve the reliability and timeliness of the FNMOC Ocean Analysis,
the data source has been changed from the development servers to the operational
servers. The data on the operational servers have the same resolution as the
development server data. However, there are three additional levels down to 5000m.
The higher resolution fields are served through a new OPeNDAP URL.
For more more details see:
Data Description/Access Page
31JUL2006 FNMOC Ocean Obs.: New decoder
The decoder for FNMOC Ocean Obs. files has been updated. The latest version reads
new QC data contained in version 2 of the profile files.
For more more details see:
Data Description/Access Page
09JUN2006 FNMOC Ocean Analysis: New higher resolution
The Global Ocean files were updated to increase the resolution to 2161 longitudes
by 1051 latitudes by 31 levels. The higher resolution fields are served
through a different OPeNDAP URL.

15JUN2005 Addition of WOA2001 and GDEM Climatologies
The World Ocean Atlas 2001 data set has been added to LAS.
This data set is served through OPeNDAP by LDEO. The Navy GDEM
monthly temperature/salinity climatology has also been added
to the Server. GDEM is available through FTP/HTTP, OPeNDAP and
LAS.

Data Description/Access Page
13JUN2005 Argo Database Consistency Checking
The USGODAE Argo Database is used for all LAS Argo operations
and data selection in the USGODAE Argo GDAC Data Browser.
To repair some problems in keeping the Argo database
synchronized with the on-line GDAC data, we have implemented
several new consistency checking procedures. First, database
records updates now depend on file modification times, instead
of the netCDF date_update field. This guarantees that any
time a file is replaces, the database is appropriately
updated. Next, we have implemented a system that ensures
synchronization between the profiles on-line and the profiles
in the database. Now, if files are removed from the GDAC,
they will also be removed from the database.
For access to Argo data an information see:
USGODAE Argo Data Access Page
08JUN2005 Live Access Server Upgrade to v6.5
Live Access Server has been upgraded to version 6.5 on the
USGODAE server. This new release contains many usability
enhancements. Along with this release, we are releasing
completely redesigned tools and visualizations for USGODAE
in-situ data, including Argo, Global Surface, and Global
Profile.

30MAY2005 Computational NOGAPS Data Replacement
Due to problems with the analysis fields for several off-time
forecasts in October 2003, we have removed the tau=3 fields
(the bad analysis fields were never posted to the server), and
replaced both the tau=0 and tau=3 fields with tau=6 and tau=9
fields from the previous watch.
For more more details see:
