Build Your Own Weather Balloon 120
Leeji writes "Here is an interesting read about one geek's project to build and launch a weather balloon. The flight recorder is a small $200 Soekris Engineering computer running Bering Linux. It also uses a Garmin GPS, HAM packet radio, an automated Aiptek Pencam Trio digital camera, army surplus batteries, and lots of geek duct tape."

On the side of reason, if you see a dupe, big deal. So don't read it the second time. It's like deleting spam; no reason to get worked up over it.... except sometimes it gets friggin' ridiculous.

Amateur (radio) balloon tracking (Score:5, Informative)
I participated in a balloon tracking experiment not too long ago. The students of Timberlane Regional High School of Plaistow NH launched several high-altitude balloons carrying APRS transmitters, as a part of their CAPSAT (Coordinated Algebra (II) & Physics Simulated Satellite) project [mv.com]. I was able to track two of them. The balloons carried GPS receivers and ham radio Automatic Position Reporting System [aprs.org] transmitters.
The launch was from Hopkinton NH. The first launch went well, and we received good signals from the balloon all the way out into the Atlantic ocean. This was quite a bit farther than they expected the baloon to travel, they had planned on recovering and reusing it
The second launch was also a success, and the baloon only traveled about 50 miles before touchdown. Map is here. [vtc.edu]
The third launch went up with the GPS receiver turned off
My tracking station consisted of a Kenwood TH-D7 radio [radiohound.com] and a PowerMac 7500 604e-180 [apple-history.com] running XASTIR [xastir.org] on Yellow Dog Linux. [yellowdoglinux.com] The full results of the day (and APRS logs for the entire hamfest) are here. [vtc.edu]

Well I wasn't launching the balloons, and I had no affiliation with the school that was doing the launch. I just heard that it would be happening and figured it would be fun to test my APRS setup in the field
Now what they SHOULD have done was to implement a "cut" signal, like the guy in this article did, to abort the flight. That would have saved the day.

Waiting for Baloon 2.0 (Score:4, Insightful)
The first time he ever tried assembling the whole thing was sitting in a park the morning of the launch. He had never weighed the whole thing until then, and then just randomly filled the balloon until it "seemed right", but that only got him about 60% of the lift he wanted.
Aligator clips on batteries. Ugh. Plus a quick run home to solder up a permanent connection while his friends hung around the park. Some staging for the week before the flight would have eliminated lots of these little problems.
He didn't check his ham frequency to see if others were using it, and his QRM walked all over other amateurs in the area, and their chatter kept his unit from receiving commands. Bad ham, no cookie!
Obscure perl bugs. Wouldn't be a geek experiment without them.

observations taken by weather observers. Every hour
on the hour, everywhere around the world, weather
observers all go outside at roughly the same time
and measure temp, dewpoint, wind direction and
speed, cloud coverage, ceiling, etc. and put it
into an "observation" that is sent to one of the
weather hubs. Then big computers generate surface
charts. Other big computers run analysis on that
data and spit out forcast models. Those models are
then sent out to people that want them. There are
usually really lame errors like weather fronts
being truncated or way off. The "forecaster" then
modifies these projected models and incorporates
then into his forecast, then sents his forecast
for his area back out to the big computers. The
weather channel then pays to steal that forecast
information from the big computer, and put it on
their screen doing little to no actual work in
the process. They also buy their pretty satellite
images from someone like kavouris probably.
Weather balloons, along with PIREPS or "Pilot
Reports" fill in some of the blanks in the upper
atmosphere and over the oceans, but I'd hazard
to guess that doppler radar technology that allows
you to know wind direction and speed at a great
distance away and great altitude is slowly filling
at least part of that.
Re:Actually, (Score:2)
Dopler radar tends to work best when there is liquid water in the air, as it uses the reflection from those droplets to determine whether the air is moving that water toward or away from the receiver. It works across a cone, and can not tell if the signal it is receiving is coming from water in the air 100 feet above you, or 10,000 feet above someone closer to the antena than you are, or 5,000 feet up on a line perpendicular to the line between you and the antena a bit closer to you. than the 10,000 foot reading.
NexGen radar is a bit better about positioning, but even it needs liquid water to reflect off of, so cold dry air is harder to measure than warm moist air.
I suspect that weather baloons will continue to be part of the weather monitoring system for several more decades.

Doppler weather radar works for wind speed and
direction pretty much always because there is
always enough reflective material in the air no
matter how much water vapor is present. It works
across a "volume coverage pattern" that is made up
of many "cones" made through repeated 360 degree
scans at varying angles. This is how you can nail
with extreme accuracy what distance and height
air is moving at what speed and direction.
Granted, I'm basing this on real world experience
as a certified Unit Control Position administrator
on the WSR-88D NexRAD doppler weather radar for
3 years.
