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 ...
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 ...
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 ...
Comparisons at low to moderate wind speeds (below 20 m/s, 45 mph, 72 km/h) are made to the NOAA Global Data Assimilation System numerical reanalysis wind product and indicate an uncertainty in CYGNSS winds of 1.4 m/s (3 mph; 5 km/h), with higher uncertainty at high wind speeds. [31]
Additionally, if a pulse Doppler weather radar is used then wind speed and direction can be determined. [44] These methods, however, leave an in-situ observational gap in the lower atmosphere (from 100 m to 6 km above ground level). To reduce this gap, in the late 1990s weather drones started to be considered for obtaining data from those ...
An anemometer is commonly used to measure wind speed. Global distribution of wind speed at 10m above ground averaged over the years 1981–2010 from the CHELSA-BIOCLIM+ data set [1] In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in ...
The "global terrestrial stilling" is not affecting in the same way the whole Earth's surface across both land and ocean surfaces. Spatially, increasing wind speed trends have been reported for some regions, in particular for high-latitudes, [18] coastal [19] and for ocean surfaces where different authors [3] [20] [4] have evidenced an increased global trend of wind speed using satellite ...
NASA renamed the spacecraft Deep Space Climate Observatory (DSCOVR) in 2003 in an attempt to regain support for the project, [3] but the mission was formally terminated by NASA in 2005. [ 11 ] In November 2008, funded by National Oceanic and Atmospheric Administration (NOAA) and the U.S. Air Force , the spacecraft was removed from storage and ...
