... imagery in visible, infrared, and "water vapor" wavelengths on a nearly global basis. Diverse rapid scanning Doppler weather radars provide high resolution data on wind fields and the types and amounts of cloud water and precipitation.

... Ground-based Doppler radar wind profilers at these stations, scanning horizontally and vertically, generate continuous vertical profiles of the threedimensional wind over the same atmospheric volume. Over the oceans, drifting and moored buoys, as well as ships of opportunity, carry instruments that measure surface air pressure, temperature, and water vapor pressure.

... Probabilistic Forecasts The ensemble of forecasts run by the international weather centers yields estimates of the variances, or uncertainties, in the NWP forecasts, as well as expected values for weather conditions. Thus, users have an indication of the reliability of a given forecast.

From page 12...
... Rather than being derived from separate atmospheric chemistry or air quality models, these forecasts can be derived from special versions of the operational global NWP models, which include representations of detailed chemical processes. The daily ensemble forecasting conducted jointly by the international centers provides quantitative probabilistic forecasts for atmospheric chemical constituents, as well as meteorological conditions.

... The center' s principal mission is to adjust the generation sources and distribution of electric power in the Northern Hemisphere grids to minimize fuel costs, conserve energy, and meet pollution constraints. When the Energy Conservation Center was first established, it also warned operators of wireless systems of impending solar events that could black out communications and upset navigation systems.

... Powerful diagnostic radars, together with radio occultation soundings from LEO satellites of electron density in the ionosphere, follow the propagation of electric currents around the globe. Cost of Weather and Climate Services to Taxpayers The total cost to taxpayers for the governmental part of the national weather information network in 2025 is a smaller fraction of the gross domestic product than it has been at any time since the major "modernization" of the NWS in the 1980s and l990s (Chapman, 1992~.
