No problem Bruce. Reading radiosondes was day one of my Intro to Meteorology
class. It's a confusing little bugger, but neat to see on a Skew-T graph how
the graphs show that you had something like fog, rain, snow, freezing rain ect.

Bruce,
The National Weather Service does that nifty little experiment for you, twice
a day, at 00 zulu and 12 zulu. They take a LOT of information (dew point,
humidity, wind speed and direction, temp, height, barometric pressure) that
goes into helping make your daily forecast!! I'm attaching an example, taken
today (March 21) from the Lake Charles Weather balloon (closest one from
Houston that goes up) at 12Z. I won't run through all the numbers, but you can
see at 10m (33 feet) the temp was 8.8c (47.84f). At the 315m (1033 feet) mark
the temp was 12.8c (55.04f). From there, the altitude continues to rise but
the temps begin to fall again.
Full radiosonde report can be found here:

This bit of radiosonde information has been brought to you by KE5MUX,
science/weather geek and hopeful future meteorologist.

i would have thought as the balloon gets higher with thinner air that the
temperature would get colder. you say it goes up. interesting. i may need to
take a look at that. neat experiment.

Especially for those that won’t be able to make it to the Houston HamFest this
weekend.
Two Balloon launches with ham gear on board. You can participate.
Live video of both launches https://zoom.us/i/2815436502
9:30 AM BLT-51 will launch
You can track with http://APRSfi search the call W5ACM-10.
You can Google APRS to find the site.
BLT-51 will be a floater, designed to be tracked via APRS and glide across the
country, and hopefully even further. The last one went to Florida in about six
hours.
Around 1:00 PM another launch BLT-52
BLT-52 is a “popper.” Designed to go up as high as possible and burst, also to
be tracked via APRS. Last August a popper flew to nearly 100,000 feet. “To the
edge of space.”
W5ACM Cross-band FM repeater will be in board with with
Input on 147435 MHz ß-----à Output on 446.550 MHz no tone, open to all to
work
A WB8ELK APRS Tracker on 144.390 MHz with the call W5ACM-11 will be on board.
You can track at http://APRS.fi search for W5ACM-11
On board also the AB5SS Smart Beeper on 10 and 20M 14.318 & 28.322 mHz, the
temperature in CW call sign and BL-52. Wach as the balloon passes through
60,000 feet the Temperature to rise.
The video will also be recorded for later playback as well, and depending on
the size of the captures, they will either be in the groups.io FILES area
https://groups.io/g/Ham-Radio-Tech-Notes/files , or my website.K5WH.net
