Wavelet-compressed HRV data

David J Taylor GM8ARV ๐Ÿด๓ ง๓ ข๓ ณ๓ ฃ๓ ด๓ ฟ ๐Ÿ‡ช๐Ÿ‡บ
 

I see we are still on wavelet-compressed HRV data. I wonder if this
will be a permanent change? The larger file size shows up well on
the bandwidth graphs - look at the increase from last Wednesday
lunchtime! I haven't seen any ill effects here such as an increase
in missing segments, file sequence errors, or the PC simply failing
to cope with the greater data rate.

I wonder if this would have been possible with direct dissemination,
rather than the greater data rates used on the DVB service?

Cheers,
David

Just to let you knwo we are thinking about you, for yesterday (Nov
01) I got no missing segments at all. If you (or anyone else) got
any missing segments, then the cause is something local in the
installation or path to the satellite. You might also want to check
the Tellique log files around the times of the missing segments in
case that shows up anything.

Cheers,
David

I hadn't spotted that, James! You are right. Better algorithms, I
expect.

One peculiarity is that the scaling for the CLAI and CTH images is
about 1% different (I hard code this from the image segment data).
I wonder why? If outlines start to become incorrect, I will have to
check this again......

Glad the rest is working....

The countries are outlined fine on HRIT images (using MSG) but
only partially on FSD and not at all on CTH.

CTH and CLAI outlines will be added in the next beta. Thanks for
reminding me.

The GOES-E image has S America outlined and the Great lakes and
even Lake Okeechobee in Florida but the coastline of N America is
missing as are state boundaries. Do I have an out of date
countries.dat or is this a feature.

As has been discussed before, either choose a different file than
Countries.dat or do not use the Inverse setting.

BTW: this would have been more appropriate for the SatSignal group.

Cheers,
David

After a reboot at 1339 yesterday cycles from 1345 to 2345 were received complete.
But today I have the following missing segments...........
Date: 2003-10-31
Cycle: 0000 - msg-ch11, seg: 4
Cycle: 0445 - msg-ch12, seg: 17 20
Cycle: 0630 - msg-ch03, seg: 4
Cycle: 0645 - msg-ch12, seg: 8
Cycle: 0945 - msg-ch01, seg: 4 - lrit-ch01, seg: 4 - lrit-ch03, seg: 4

I have V2.3.0a of the Tellique software, perhaps an upgrade to V2.3.1 would be the answer.
I will email Eumetsat and request for an upgrade.

Hi Nicola,

currently, IR and WV channel are being calibrated. You will find information
provided by Eumetsat at:

Hi folks,
does anyone know if SEVIRI data calibration is already operational ?
I mean, did EUMETSAT provide the operational calibration coefficient for all
the 12 SEVIRI bands (VIS, WV, IR)? If yes, could you please indicate me
where can I find such information?
Thanks in advance

Yes, excellent here in Dunblane. Had to wait for cloud clearing about
22.00 clock but knew it was going to thanks to MSG and GSS4 (keeps mail
on
topic !)
Last night's X10 flare's CME struck us about 17.00 and started another
'severe' geomagnetic storm. Magnetic field has turned south so looks
like
more auroras tonight. All 'data' sites are virtually unusable at the
moment due to traffic so difficult to get up to date info.
Fingers crossed for clear skies.

The count to radiance value conversion coefficients are in the
prolog header data. The radiance to temperature conversion is at:

/en/area4/msg/dataservices/brightness_to_temperature.html

on Eumetsat's Web site. My MSG Data Manager does all the
calculations for you, if you wish, and outputs temperature
calibrated images.

The licence is free, but you still need to pay for the software and
hardware. The Eumetsat/Tellique software converts the DVB data
stream into segments that my software can decode, and the hardware
is required for 15-minute (rather than 6 hourly) access. It is a
small device that plugs into a USB port.

I have the original version. Indeed I was given a special
password to download an upgrade to get me to 2.3.0a !

Same here....

What's your opinion David. Should I upgrade... are there any
known benefits or indeed have I restrictions with the older
software.... or should I let happy sleeping dogs lie !
It seems from what I have heard that the majority of the
improvements are automation in installation. Mine was a complete
manual job.
Douglas, there is supposedly a lower chance of missing data with the
newer version. A number of us are running with it sucessfully, so
my advice would be for all users to upgrade. How Eumetsat wish to
mechanise this is currently unknown. As you note, the password
protected FTP site would be one possibility, as that mechanism is
already there....

Cheers,
David
