Cloud seeding is undertaken by dispersing substances into the air that serve as cloud condensation or ice nuclei. Common agents include silver iodide, potassium iodide, and dry ice, with hygroscopic materials like table salt gaining popularity due to their ability to attract moisture. Techniques vary from static seeding, which encourages ice particle formation in supercooled clouds to increase precipitation, to dynamic seeding, designed to enhance convective cloud development through the release of latent heat.
Environmental and health impacts are considered minimal due to the low concentrations of substances used. But concerns persist over the potential accumulation of seeding agents in sensitive ecosystems. The practice has a long history, with initial experiments dating back to the 1940s, and has been used for various purposes, including agricultural benefits, water supply augmentation, and event planning. Legal frameworks primarily focus on prohibiting the military or hostile use of weather modification techniques, leaving the ownership and regulation of cloud-seeding activities to national discretion. Despite skepticism and debate over its efficacy and environmental impact, cloud seeding continues to be explored and applied in regions worldwide as a tool for weather modification.
HARRP on the other hand, or whatever they call it now. Works by beaming radiowaves into pockets of the ionosphere, where they can heat the air to a plasma, giving them the ability to nudge the jetstream one way or the other. I know another thing they can do is build up a electromagnetic charge and emp entire continents this way. Lots of military potential with this one.
Nowadays the original HARRP site was given to a University for research purposes. I imagine after decades of research they figured out to miniaturize this technology and stick it on satellites. Or perhaps the facility at the south pole is the next step in evolution of the technology. From what I understand as well, most first world countries have their own HARRP stations.
The High-frequency Active Auroral Research Program, or HAARP, is a scientific endeavor aimed at studying the properties and behavior of the ionosphere. "The ionosphere stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space. Along with the neutral upper atmosphere, the ionosphere forms the boundary between Earth's lower atmosphere — where we live and breathe — and the vacuum of space." (NASA)
Operation of the research facility was transferred from the United States Air Force to the University of Alaska Fairbanks on Aug. 11, 2015, allowing HAARP to continue with exploration of ionospheric phenomenology via a land-use cooperative research and development agreement.
HAARP is the world's most capable high-power, high-frequency transmitter for study of the ionosphere. The HAARP program is committed to developing a world-class ionospheric research facility consisting of:
The Ionospheric Research Instrument, a high power transmitter facility operating in the High Frequency range. The IRI can be used to temporarily excite a limited area of the ionosphere for scientific study.
A sophisticated suite of scientific or diagnostic instruments that can be used to observe the physical processes that occur in the excited region.
The in-ice component of IceCube consists of 5,160 digital optical modules (DOMs), each with a ten-inch photomultiplier tube and associated electronics. The DOMs are attached to vertical “strings,” frozen into 86 boreholes, and arrayed over a cubic kilometer from 1,450 meters to 2,450 meters depth. The strings are deployed on a hexagonal grid with 125 meters spacing and hold 60 DOMs each. The vertical separation of the DOMs is 17 meters.
Eight of these strings at the center of the array were deployed more compactly, with a horizontal separation of about 70 meters and a vertical DOM spacing of 7 meters. This denser configuration forms the DeepCore subdetector, which lowers the neutrino energy threshold to about 10 GeV, creating the opportunity to study neutrino oscillations.
I watched a documentary about this place recently, and apparently they have some grad students up there all year round. About a km or something from the sensor arrays. They are there to reboot the system immediately if it should break or crash or whatever.
If all its doing is watching for neutrinos, why spend billions a year to make sure this thing has as minimal downtime as possible, just seems strange to me.
Cloud seeding is a bit different than say, HARRP.
They have been experimenting with seeding clouds for a long time.
