Sounds like y'all are talking about moving through the tropopause; from the troposphere, and upward through the stratosphere.  Temperature decreases (generally) with altitude in the troposphere, because this region is ruled by thermal heating of the ground (and associated boundary layer), convection, and adibatic expansion.  Once you get into the stratosphere, temperature increases with altitude due to heating by UV radiation.  (Obviously this is a short form description.)

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://APRS.fi  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 147.435 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
