![]() Melting Arctic ice is often associated with global warming. Iceberg buildersĪround 13 percent of Arctic ice is currently being lost per decade. The small droplets in the clouds scatter light, making clouds appear white, and in turn these white clouds would reflect more sunlight away from Earth. This fine spray of seawater would reduce the average droplet size within the surrounding clouds. Water would then be pumped from the sea and sprayed into the sky through these towers. The towers would be constructed on a fleet of autonomous boats, floating on the ocean surface. ![]() This is the idea behind cloud-whitening towers, which would aim to brighten clouds in order to reduce the warming of the planet, according to the BBC. Bright white clouds can be pleasing to the eye, but they also hold another useful property - they can reflect sunlight back into space, along with the heat energy it carries. The color of a cloud depends on its particle size and composition. The country carried out cloud-seeding in the capital, to ensure that the rain fell before events like the opening ceremony, rather than during them. In 2008, China used its weather-modification programme to control weather forecasts for the Beijing Olympics, according to the BBC (opens in new tab). When the events of Operation Popeye were publicized, a ban was put in place by the European Modification Convention to prevent military tactics that controlled the weather. The canisters were ignited to release the particles into the clouds. To do this, military pilots flew over chosen regions with canisters of silver or lead iodide. Operation Popeye used the rain as a weapon to destroy roads and flood rivers. troops were more prepared for the extensive rainy season, according to documents posted online at the Office of the Historian (opens in new tab). The plan was named Operation Popeye and meant that the U.S. The aim was to prolong the monsoon season in Vietnam, making fighting more difficult for the enemy. army used cloud seeding to alter the weather. In 1974, during the Vietnam War, the U.S. As they fall, they melt to become raindrops. Eventually, the ice crystals become too heavy to remain in the air. ![]() As the water and silver iodide combine, ice crystals form. Because these particles have a similar structure to ice, the water droplets in the cloud–which are too small to fall as rain– surround the silver iodide, according to Encyclopaedia Britannica (opens in new tab). Using aircraft, drones or rockets, small particles of silver or lead iodide are released into the sky. (Image credit: Getty)Ĭloud seeding is a method used to make clouds rain. With the aid of a flow cell and low flow pump, you can now accurately monitor DO and other parameters from the surface without the need for an insitu water quality meter.Silver iodide canisters can be carried through clouds by a plane. The ECO kit allows you to correctly monitor the drawdown effects within the well during low flow sampling, while obtaining water quality measurements directly from within the monitoring bore. If you are looking for a complete low flow sampling and monitoring kit, we have the solution! The ECO Low Flow Kit incorporates the Geotech Portable Low Flow Pump, along with a Hydrolab Quanta with Flow Cell and Heron Drawdown Meter. This is especially useful for mining applications where you have extra deep production bores. We can customise both dedicated and portable sampling systems to suit your particular application, even to a depth of 300m with the aid of a drop tube assembly. Our monitoring systems are light weight and portable, without bulky compressed air bottles, as we understand your groundwater monitoring projects may take you anywhere. Over the years ECO Environmental have developed customised low flow systems, especially adapted to suit Australian conditions.
