NSA OPS OLD NEWS:
[10/02/06]:
Data now from the DMF
The data we use for Quick-Looks (QLs) and Quality Assurance is now
downloaded from the ARM Data Management Facility (DMF). This saves
us some bandwidth to the North Slope, but some data get in a bit
delayed and in chunks (e.g. the TSI).
[09/26/06]:
IOP camera from sky-deck
We have an extra live (near real-time) camera going because of the
Radiometer Intercomparison IOP. Our friend the Total Sky Imager (TSI)
is also back. Both images can be seen at the
Barrow (C1) page.
The IOPCam updates every 5 minutes! There is also a daily movie from
the TSI images there.
[07/24/06]:
Disk failure (again)
Just when we thought we had seen the last of the SCSI disk problems
they re-appeared.
We removed the entire SCSI sub-system this time, good riddance.
Hopefully we will live in peace forever after. No important data was
lost but it looked pretty grim for a while.
We are not back to 100% in terms of backup and redundancy, but
we will address this issue soon.
You might notice temporary outages (e-mail, web, or data-base) as we
move things around a bit on the remaining disks.
[06/21/06]:
Power failure
One of our UPS systems failed on us and took out both nanuna and agvik.
There was some issues with confused disks afterwards, but we worked
through it. Web and e-mail services should be back to normal.
Thanks again to Dana for being Hans' hands :-)
Dana will go on vaccation starting 6/23, good thing this happend before!
Hans is available as usual by e-mail.
Happy solstice!
[03/23/06]:
Sync your time with ours
We have been running a time service (NTP) on nanuna for some time, but
we have recently upgraded it and made it available for everyone.
You can check on our time service and synchronize your watch here.
Accurate time-keeping is vital for collecting data and performing automated tasks.
[03/15/06]:
Snow-birds are back again
The multi-filter radiometers (MFRs) have returned to the sites after their
winter break in sunnier surroundings. Data are available from about March
15. We are still waitning for news about the TSI.
[08/16/05]:
Disk failure in redundant array
We lost a disk in one of our disk arrays. This means our redundancy
strategy is working as intended - had this been a lone drive failure,
nanuna would be down and I would be on a red-eye to Fairbanks.
We are continuing as normal and new disks are under way (thanks
Jeff!). Expect minimal down-time as we replace the faulty disk,
notices will be sent out. [08/31/05] Update: Today both
disks in the disk array were replaced and we are
100% restored. Thanks to Dana!
[08/12/05]:
Present Weather Sensor (PWS) QL added
A new Quick Look (QL) has been added for the Present Weather Sensor
on the surface meteorological tower (mettwr) in Barrow (C1).
Thanks to Dana!
[06/23/05]:
Nanuna has been upgraded
Our servers, "nanuna" and its spare twin "anja", has been upgraded.
Hopefully you can't notice anything, the upgrade is all behind
the scenes stuff. For example, nanuna now has more memory and is
about twice as fast after hardware updates. The new systems are
based on the Debian "stable" Linux distribution. If you
notice any problems, please contact Hans or Dana.
[06/20/05]:
Another New Addition to the UAF/OPS Team
We welcome Martin Stuefer into our group!
[05/15/05]:
New Addition to the UAF/OPS Team
On Sunday 5/15 at 1:33 am, we got a new member of the NSA/UAF Operations
Team. Her name is Sonja, and as she is not much more than
8 lbs 8 oz for the moment, we expect it will be some time before
she is ready to wrestle polar bears. Congrats Dana and Martin!
[09/16/04]:
Firewall installed
A firewall is now in place on nanuna. If something that used to
work no longer does, please contact Hans Eide or Dana Moudry.
E-mail and web-services should be entirely unaffected.
[06/14/04]:
Another disk crash
After 471(!) days of uninterrupted up-time we had another disk
failure on our server nanuna. This time we lost a disk dedicated
to backups so we are back and working as normal already.
[04/15/04]:
New VCEIL and METTWR QLs
The new met-tower ingest is shaping up and so we have a new stream
of quick-looks coming from there. Also check out the new ceilometer
quick-looks that are now made using IDL instead of Matlab.

[04/09/04]:
The return of the *MFRs.
Our "snowbirds", the MultiFilter Radiometers (MFRs), have returned to
the cold north after a prolonged calibration wintering in the
south. You can now find quick-looks for these data streams here.
[03/11/04]:
The NSA OPS web e-mail interface
on nanuna has been upgraded to a newer version.
Please let us know if there are any problems (or if you need an account).
Also note that our security certificates has changed.
[03/05/04]:
There is now a new official
NSA Logo
that you can download
here.
The new logo reflects that the NSA site is becoming a part of the
ACRF Climate Research Sites.
[08/11/03]:
Level B1 data from the Normal Incidence Multi-channel Radiometer
(NIMFR) at both Barrow (C1) and Atqasuk (C2) is now
available
As of 8/10/03, QLs made from only from the new B1 level data.
The old QLs based on A0 data are still available of course.
Please look for new(old) QLs under the nsanimfrC1.b1(a0) and
nsanimfrC2.b1(a0) streams.
[05/15/03]: Telephone conference minutes available
There is now searchable/browsable interface for online
NSA OPS telephone conference minutes.
We intend to add more documents to this data-base in the future.
[04/15/03]: Skyrad and groundrad level B1 data available
Starting 3/27/03 there are no longer QLs made from a1 data,
simply because the ingest is now doing b1 level data and no
a1 level data is available anymore. Please look for QLs under
the nsaskyrad60sC1.b1 and nsagndrad60sC1.b1 streams.
