The Parker Solar Probe was launched Aug. 12, 2018 with the mission of coming within 4 million miles of the sun's surface to study the formation of the solar wind.. The spacecraft is designed to ...
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 ...
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 ...
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 ...
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]
The NASA Advanced Composition Explorer has monitored the solar wind at the L 1 point from 1997 to present. In addition to monitoring the solar wind, monitoring the Sun is important to space weather. Because the solar EUV cannot be monitored from the ground, the joint NASA - ESA Solar and Heliospheric Observatory (SOHO) spacecraft was launched ...
The PSP and ESA-NASA Solar Orbiter (SolO) missions cooperated to trace solar wind and transients from their sources on the Sun to the inner interplanetary space. [ 91 ] In 2022, PSP and SolO planners collaborated to study why the Sun's atmosphere is "150 times hotter" than its surface.
The minimum temperature the countdown may proceed at was determined by a table of temperatures determined by wind speed and relative humidity ranging from 36 °F (2 °C) (high humidity, high winds) to 48 °F (9 °C) (low humidity, low winds). In no case was the space shuttle to be launched if the temperature was 35 °F (2 °C) degrees or colder.
