WW2D Plus One - an update to WW2D providing a 3D view. Punt was a fork of the .NET NASA WorldWind project, and was started by two members of the free software community who had made contributions to WorldWind. Punt was based on the code in WorldWind 1.3.2, but its initial release has features not found in WorldWind 1.3.2 or 1.3.3 (such as ...
The latest release of the Global Wind Atlas (3.0) was launched on October 25, 2019, featuring further methodological modeling improvements, all new raw data (based on 10 years of mesoscale time-series model simulations), data coverage spanning 200 kilometers offshore, two additional heights (data now at 10, 50, 100, 150 and 200 m above ground ...
A wind atlas contains data on the wind speed and wind direction in a region. [1] These data include maps , but also time series or frequency distributions . A climatological wind atlas covers hourly averages at a standard height (10 meters) over even longer periods (30 years) but depending on the application there are variations in averaging ...
If the wind speed is forecast to be 200 knots or greater, the wind group is coded as 99 knots. For example, when the data appears as “7799,” subtract 50 from 77 and add 100 to 99, and the wind is 270° at 199 knots or greater. When the forecast wind speed is calm, or less than 5 knots, the data group is coded “9900,” which means light ...
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
On September 1, 1994, the weather radar model RDR-4B of the Allied-Signal/Bendix (now Honeywell) became the first predictive wind-shear system to be certified for commercial airline operations. In the same year, Continental Airlines became the first commercial carrier to install an airborne predictive wind-shear detection system on its aircraft.

QuikSCAT consists of an active microwave radar that infers surface winds from the roughness of the sea surface based on measurements of radar backscatter cross section, denoted as σ 0. σ 0 varies with surface wind speed and direction relative to the antenna azimuth, incidence angle, polarization, and radar frequency. QuikSCAT uses a dual-beam ...
