Talk:Radiosonde

Untitled

"The Russian Venus probe VeGa abandoned in 1984 two radiosondes in the atmosphere of Venus, which could be tracked two days long."

This sentence looks like it needs to be reworded but I don't know the details to know if it is that the Russian probe VeGa has been abandoned, or whether the writer meant to say that the probe released two radiosondes. I will do this edit if no one seems to be tracking this page.

403 MHz or 1700 MHz?

The NWS factsheet link at the end of this article says that radiosondes transmit between 1668.4 and 1700 MHz. There's no mention of 403-406 MHz. Radiosondes sent aloft in Australia were in that frequency range, which was in fact slightly broader at one time (402-406MHz). A range is needed so adjacent stations can off-tune from each other, and to enable a second release (where first sonde fails but is still transmitting) where the first would interfere with the second.

403MHz is used extensively in Australia where in 2007 they were using Vaisala RS-92 sondes, I know Australia are not the only users of Vaisala sondes so 403MHz is likely to be used in many locations throughout the world Hoxygt 06:47, 6 June 2007 (UTC)

History?

I think this [1] should go into a history section and be expanded. At the moment it rather reads as though the Russians invented it out of nowhere William M. Connolley 21:18, 8 October 2007 (UTC)

I agree the Signal Corps (United States Army) was instermental in developing this technoligy alongside early radar most of the met. subjects tend to leave that out.Brian in denver (talk) 23:33, 9 August 2008 (UTC)

Looks like the Russians invented the first weather radiosonde. That's a good fact to have (it actually helped me in my research, because now I know where Vernov got the idea of building the first cosmic ray radiosonde a couple years later). Other radio transmitters on balloons preceeded the russian invention, but not sure those are "radiosondes" as such. DonPMitchell (talk) 05:31, 14 August 2008 (UTC)

On further study, the history is complex. There is a long scholarly article about the history of the radiosonce by DuBois, in Smithsonian Studies in History and Technology. I'll try to update the page with that information. 71.231.42.134 (talk) 17:30, 14 August 2008 (UTC)

I organized the history information into a separate section. I think it addresses the concerns mentioned above -- the involvement of the US Signal Corps, etc. DonPMitchell (talk) 04:06, 25 November 2009 (UTC)

Etymology?

Why is it called that? why not "radio probe"?

seems that "sonde" was carried over from French (or German), instead of translating it.

i think some historical information on that could be interesting as a bit of Trivia. — Preceding unsigned comment added by 84.183.51.236 (talk) 17:53, 24 August 2017 (UTC)

Rawinsonde

The entry claims that radiosondes act as a rawinsonde because they contain some kind of radar reflector. This is not correct, the reflector section of a balloon train is separate and is generally attached directly below the balloon, with the radiosonde's string unwinder attached just below the radar target. While there may well be radiosondes which incorporate some sort of radar reflector, they were never used in Australia and given how large radar reflectors are, it's hard to envisage a design that wasn't very unwieldy. Of course a GPS sonde is in effect a rawinsonde, but there is no radar involved. — Preceding unsigned comment added by 175.33.244.14 (talk) 13:23, 22 April 2018 (UTC)
