Yeah...they had problems as well last night, Dave. Different bird, which means that two planes are probably down now. Puts more stress and flight time on the remaining birds.

I saw the one go back last night also. I feel like a newbie so far out of the loop it's not funny. I am home and home to stay now...been a long long run but it sure feels good to sit here in my 'command' chair once again! Now to get the command back. :lol:

I'll be around as much as I can be.

I assume they will continue recon all the way until impact on the NE US? I know they sometimes do winter storms and since this will be a hybrid they definitely need to do it here as well.

I have a highly experimental feature that I developed a month ago and thought since NOAA was releasing Airborne eXpendable BathyThermograph (AXBT) buoy data in real time for Sandy I would go ahead and allow people to use it now rather than waiting until 2013.

You take the text here:
ftp://tgftp.nws.noaa.gov/data/raw/so/sovx02.kwbc..txt

And put it into my decoder here:
http://tropicalatlantic.com/recon/manual/

Only NOAA AXBT data is available in real time. My site will not automatically decode the data or have it in Google Earth until probably mid 2013 when I hope to finish rewriting my recon system.

Perhaps in the future I will be able to get Air Force data on a delayed basis. (The decoder is already setup to decode the different data type for the Air Force and also an older NOAA format.)

If you notice any errors let me know.

AXBTs are released from the aircraft.

"The AXBTs transmit sea surface temperature versus depth as the thermistor sinks through the water column. AXBTs provide key information about ocean temperature (an important factor in determining the possible strength a hurricane may reach)."

http://www.aoml.noaa.gov/hrd/HRD-P3_exp.html
http://www.aoc.noaa.gov/instrumentation.htm

"An expendable instrument that is dropped from an aircraft and used to measure the profile of temperature in the water column. The probe consists of a thermistor in a weighted, streamlined case. It falls freely at a fixed, known rate so that the elapsed time can be converted to depth. It is connected by a thin, freely unwinding wire to a small buoy with a radio transmitter through which the data are transmitted to the aircraft, which continues its flight.

Pressure drop from 967mb to 961mb between the last two vortex msg sounds like a fast drop.

great work Chris. Can't wait for the final product. Thanks for all you do.

...

Very cool.

Now I need to add AXBT data to the chat bot recon reports ...

Was the 957 earlier a bogus measurement? Since the last VDM had 962 and I doubt it weakened in between?

Waiting on this next pass to see what they get on it from the AF flight.

it was taken by two different planes, so have no idea. They are getting fairly close to making another measurement, though. (the plane that got the 957) I will note the 957 was taken
Product: Air Force Vortex Message (URNT12 KNHC)
Transmitted: 27th day of the month at 12:08Z
The 962
Product: NOAA Vortex Message (URNT12 KWBC)
Transmitted: 27th day of the month at 13:20Z

So they were a little over an hour apart, though the NOAA flight that got the 962 also got 961 2 hours before the 957 by AF.

good to have you back in the pilot's seat, Dave!

#172 Postby **Dave** » Sat Oct 27, 2012 8:58 am

134930 2853N 07610W 8433 01157 9622 +203 +181 012015 017 022 005 00

962 mb's from AF 302 on 2nd pass. With NOAA2 bringing in the same pressures I'd question the 957 mb from the first drop.

My opinion only....lost my signature somewhere along the line....

#173 Postby **RL3AO** » Sat Oct 27, 2012 9:09 am

Think they missed the center a bit.

They say it's like riding a bike..you never forget....HA!

#175 Postby **CrazyC83** » Sat Oct 27, 2012 9:34 am

Probably the center is hard to find. I would average the two and say 960mb.

#176 Postby **Dave** » Sat Oct 27, 2012 9:38 am

Could someone take over for awhile? Still adjusting to these new glasses and getting one splitting headache....argh! They say a few more days and I should be normal again...no comments from the gallery.

#177 Postby **HenkL** » Sat Oct 27, 2012 9:40 am

I''ll take over, Dave.

Thanks Henk...go ahead and I'll break here.

Wonder why AF and NOAA have such a big difference in min. central pressure ... 959mb vs 965mb - only 4 minutes apart.

EDIT: I see the AF measurement of 959mb was a dropsonde - I'll trust that.

No data for more then half an hour.
