At the Met Office, we use a blend of cutting-edge technology and time-tested methods to observe and record the atmosphere’s most important elements. Here’s how we measure sunshine, cloud, visibility ...

Abstract: An optical fiber anemometer based on a flexible multi-FBG curvature sensor is reported. The probe is comprised of a structured polymer shell with embedded single-mode fibers with written ...

Abstract: Wind is a major factor that can inhibit the process of tracking the source of gas leakage by the olfactory mobile robot, as it can reduce and even remove the gas concentration. This will ...

Synthesis of nanostructured cubic phase SnO 2 thin film and its trace-level sensing of CO gas This study presents a cubic phase SnO 2 thin film gas sensor with ultra-high CO sensitivity and 1 ppb ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Tornadoes are vertical funnels of rapidly spinning air. Their winds may top 250 miles an hour and can clear a pathway a mile wide and 50 miles long. Twisters are born in thunderstorms and are often ...
