[Datastream #SXB-674928]: GOES East West imagery...



Hi Gilles,

re:

Boulder is very nice in the spring and summer!

No.

re:

Before the IDV 5.3 release, the only "unit" that one could display
from locally held images in AREA file format was 'Brightness'.  If one
wanted to display IR images as Temperatures, then the data had to be
served from a McIDAS-X ADDE server.  Yuan is adding the support for
displaying locally held imagery in all of the calibrated units that
should be available for the type of image.

The easiest way to do this is to create a script that will produce the
display you want and then run the script from a cron entry (if you
don't know about 'cron', it is a Unix/Linux facility that allows one
to run jobs at certain times).

There are tutorials for the IDV that address putting together scripts
to produce displays.  After you have a working script, having run by
a cron entry is very simple, and information on running things from
cron can be found through links shown in Google (tm) searches.

There are now 0.25 degree global GFS fields being distributed in the
IDD CONDUIT datastream.  I believe that these data are being served by
the TDS (THREDDS Data Server) on one or more of the machines where
we are running TDS.

Our firewalls have always allowed all traffic to our ADDE and TDS servers.
The only time we block access is when a site abuses access to these servers
(for example, when a site kicks off 1000 simultaneous connections, and basically
creates a defacto denial of service attack that prevents others from getting
access to data).  Why your access was not working before is a mystery to me.

re:
> And the last one, is that I do not see any workshops this year at UNIDATA.
> No workshop this summer or fall?

We will be holding our annual training workshops this fall.  The information
for the next regularly scheduled series of workshops is available on our
website:

re:
> Thanks again and hi to all the team,

No worries, and will do.

Cheers,
