Ze sproeien.

En? Ook meteorologisch gebruik of radarbedrog.

Bij militaire oefingen om de radars te testen smijten ze er zelfs mee om extra wolken te vormen. Of zie wiki...

Tegenwoordig wordt antiradarsneeuw nog wel gebruikt door vliegtuigen of schepen om zich te verdedigen tegen geleide raketten.

Störung des Wetterradars durch Düppelabwurf über der Nordsee

Meteorologischer Einsatz

Außer zur Radartäuschung werden Düppel in der Erdatmosphärenforschung zur Untersuchung von Winden in der Hochatmosphäre verwendet. Hierfür werden sie mit Hilfe von Höhenforschungsraketen in die entsprechenden Schichten gebracht und ihre Flugbahnen mit Radar verfolgt. Auf diese Weise können hochatmosphärische Luftströmungen vermessen werden.

meteorologisch gebruik

Naast radarbedrog worden kaf gebruikt bij onderzoek aan de aardatmosfeer om winden in de hoge atmosfeer te bestuderen. Daartoe worden ze met behulp van sonderingsraketten in de juiste lagen gebracht en worden hun banen met radar gevolgd. Op deze manier kunnen zeer atmosferische luchtstromen worden gemeten.

Alle smijters, alle vliegtuigen, alle uitleg:

En ook daarom dat ze nog altijd sproeitesten doen met bepaalde partikels om het beste effect te verkrijgen, helaas eerder hopeloos.

Aircraft most reliable geoengineering technology, finds new study

26 August 2020

A new UCL study has investigated some very unusual technologies for manipulating the climate. It concluded that conventional aircraft are presently the most reliable option.

Solar geoengineering would require tiny reflective particles to be launched into the stratosphere - which starts at around 20 km up. These aerosols would reflect sunlight – cooling the planet, and counteracting global warming. Millions of tons would be needed – and getting this much material 20 km up is a tall order, requiring novel engineering.

The new UCL study reviews technologies that could offer reduced costs or superior performance, compared to familiar aircraft-based designs. The options considered included several novel types of gun system, as well as a variety of balloons, rockets and airships.

Despite the breadth of technologies considered, conventional planes still came out well in the analysis. However, customising them for such an unusual mission is expensive. Planes can fly just high enough to work – and their steady, level flight makes it easier to spread reflective particles evenly. This crucial advantage is not available from most other technologies – and that could be a deal breaker for competitor approaches. Only airships share this ability to finely-control aerosol injection.

Nevertheless, many alternative approaches are rapidly improving. These include Elon Musk’s reusable rockets and Hyperloop vacuum train. Such technologies could therefore become more competitive, in future. Many novel approaches can get to higher altitudes than aircraft. If finely-controlling aerosol injection turns out to be unnecessary, the cost or altitude advantages of these competitors may eventually see aircraft fall behind. However, despite their Hollywood sci-fi looks, railguns probably won't ever work – as they wear out too quickly.
