The radar operation is quiet simple: a radar transceiver sends a pulse to the air and the weather phenomena (tornado, rain, etc..) responds with a signal back. Rain? AUSTIN (KXAN) — Researchers at Duke University have developed a new tool to find the effectiveness of the various types of masks people are using to stop spread during the COVID-19 pandemic.And some offer less protection than others, researchers found.Duke researchers say, naturally, the most effective mask was Other masks that performed well in the test were three-layer surgical masks and cotton masks — which can be made at home.Shockingly, in some cases, certain types of masks made particle exposure even worse, according to the study.“We were extremely surprised to find that the number of particles measured with the fleece actually exceeded the number of particles measured without wearing any mask,” Martin Fischer, one of the study’s authorsNeck fleeces were shown to break down larger droplets into smaller particles, which can more easily slip through and out.The experimental setup is relatively simple: someone wearing a face mask would speak in the direction of a laser beam inside a dark box.
In the last ten years, atmospheric phenomena have increased exponentially, and with it thousands of lives and infrastructure have been affected.

Power Transmission. Weather Type Radar The weather type detection uses a combination of hi-resolution model data, along with ground observations to show whether rain, sleet, snow, hail or freezing rain is falling. Due to the low power nature of these radars, they can be solar powered and with a wireless link a complete of the grid radar systems can be deployed.Our product will contribute to the safety and the well-being of countries and communities that can’t afford the cost of actual commercially available radars and will improve the existing weather prediction infrastructures. Rain? MAY 2014 RAFAEL H. MEDINA SANCHEZ B.E.E., UNIVERSIDAD TECNOLOGICA DE BOLVAR M.Sc., UNIVERSITY OF PUERTO RICO MAYAGUEZ Ph.D., UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Professor David J. McLaughlin Phase array antennas are a promising technology for weather surveillance radars… Rail Weather. Rain? Snow? To date our community has made over 100 million downloads. Easy to use weather radar at your fingertips! Ice? These radars are extremely portable and usually don’t need any specific infrastructure to operate. Currently, weather radars are the main instrument to forecast events and help countries to develop mitigation plans that protect people and infrastructure. Developing a weather radar network with these devices could lower the costs up to 10 times compared to a common weather radar for the same coverage.The radar operation is quiet simple: a radar transceiver sends a pulse to the air and the weather phenomena (tornado, rain, etc..) responds with a signal back. With the advent of global warming, weather prediction and damage mitigation has become a world issue. Track storms, and stay in-the-know and prepared for what's coming.
