Mesowest
MesoWest is an ongoing cooperative project, started in 1996, to provide access to current and archive weather observations across the United States. Weather observations include but are not limited to: temperature, humidity, wind speed, wind direction, and precipitation. Data are collected from a variety of organizations. Some stations participate in voluntary weather observing networks such as the Citizen Weather Observer Program. Others are part of mesonets that are managed by private firms or federal/state/local agencies. These data are available for a multitude of uses. Over 20,000 weather stations actively report to the MesoWest database. Parties involved in this project include researchers at the University of Utah, forecasters at the Salt Lake City National Weather Service Office, the National Weather Service Western Region Headquarters, and personnel of participating agencies, universities, and commercial firms. Support for this project is being provided by the Nationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesonet
In meteorology and climatology, a mesonet, portmanteau of mesoscale network, is a network of automated weather and, often, environmental monitoring stations designed to observe mesoscale meteorological phenomena and/or microclimates. Dry lines, squall lines, and sea breezes are examples of phenomena observed by mesonets. Due to the space and time scales associated with mesoscale phenomena and microclimates, weather stations comprising a mesonet are spaced closer together and report more frequently than synoptic scale observing networks, such as the WMO Global Observing System (GOS) and US ASOS. The term mesonet refers to the collective group of these weather stations, which are usually owned and operated by a common entity. Mesonets generally record in situ surface weather observations but some involve other observation platforms, particularly vertical profiles of the planetary boundary layer (PBL). Other environmental parameters may include insolation and various variables of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citizen Weather Observer Program
The Citizen Weather Observer Program (CWOP) is a network of privately owned electronic weather stations concentrated in the United States but also located in over 150 countries. Network participation allows volunteers with computerized weather stations to send automated surface weather observations to the National Weather Service (NWS) by way of the Meteorological Assimilation Data Ingest System (MADIS). This data is then used by the Rapid Refresh (RAP) forecast model to produce short term forecasts (3 to 12 hours into the future) of conditions across the contiguous United States. Observations are also redistributed to the public. Origin The CWOP was originally set up by amateur radio operators experimenting with packet radio, but now includes Internet-only connected stations, as well as amateur radio Automatic Packet Reporting System (APRS) stations. , more than 13,000 stations worldwide report regularly to the network.

Weather
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere. Weather refers to day-to-day temperature, precipitation, and other atmospheric conditions, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth. Weather is driven by air pressure, temperature, and moisture differences between one place and another. These differences can occur due to the Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations: the Hadley cell, the Ferrel cell, the polar cell, and the jet stream.

Satellite Imagery
Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world. Satellite imaging companies sell images by licensing them to governments and businesses such as Apple Maps and Google Maps. History The first images from space were taken on Sub-orbital spaceflight, sub-orbital flights. The U.S-launched V-2 flight on October 24, 1946, took one image every 1.5 seconds. With an Apsis, apogee of 65 miles (105 km), these photos were from five times higher than the previous record, the 13.7 miles (22 km) by the Explorer II balloon mission in 1935. The first satellite (orbital) photographs of Earth were made on August 14, 1959, by the U.S. Explorer 6. The first satellite photographs of the Moon might have been made on October 6, 1959, by the Soviet satellite Luna 3, on a mission to photograph the far side of the Moon. The Blue Marble ...

Weather Station
A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate. The measurements taken include temperature, atmospheric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken with as few other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once daily, while automated measurements are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature (SST), wave height, and wave period. Drifting weather buoys outnumber their moored versions by a significant amount. Weather instruments Typical weather stations have the following instruments: * Thermometer for ...

Government Agency
A government or state agency, sometimes an appointed commission, is a permanent or semi-permanent organization in the machinery of government that is responsible for the oversight and administration of specific functions, such as an administration. There is a notable variety of agency types. Although usage differs, a government agency is normally distinct both from a department or ministry, and other types of public body established by government. The functions of an agency are normally executive in character since different types of organizations (''such as commissions'') are most often constituted in an advisory role—this distinction is often blurred in practice however, it is not allowed. A government agency may be established by either a national government or a state government within a federal system. Agencies can be established by legislation or by executive powers. The autonomy, independence, and accountability of government agencies also vary widely. History Early exa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

K–12 Education
K-1 is a professional kickboxing promotion established in 1993, well known worldwide mainly for its heavyweight division fights and Grand Prix tournaments. In January 2012, K-1 Global Holdings Limited, a company registered in Hong Kong, acquired the rights to K-1, and is the current organizer of K-1 events worldwide. Founded in 1993 by karateka Kazuyoshi Ishii, at its height in the late 90s and the 2000s under the ownership of the Fighting and Entertainment Group (FEG), K-1 was the largest and most prestigious "Kickboxing" organization in the world. With thousands of fighters and watched by millions of fans around the world. K-1 also promoted mixed martial arts events, with some events having both kickboxing and MMA matches on their cards (such as their Dynamite!! series). However, since 2010 K-1 started to lose its status of top organization, as FEG started to have financial issues, not being able to organize big events or pay huge prize money, eventually going bankrupt, and su ...

Dimensional Analysis
In engineering and science, dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric current) and units of measure (such as miles vs. kilometres, or pounds vs. kilograms) and tracking these dimensions as calculations or comparisons are performed. The conversion of units from one dimensional unit to another is often easier within the metric or the SI than in others, due to the regular 10-base in all units. ''Commensurable'' physical quantities are of the same kind and have the same dimension, and can be directly compared to each other, even if they are expressed in differing units of measure, e.g. yards and metres, pounds (mass) and kilograms, seconds and years. ''Incommensurable'' physical quantities are of different kinds and have different dimensions, and can not be directly compared to each other, no matter what units they are expressed in, e.g. metres and ...

Temporal Resolution
Temporal resolution (TR) refers to the discrete resolution of a measurement with respect to time. Physics Often there is a trade-off between the temporal resolution of a measurement and its spatial resolution, due to Heisenberg's uncertainty principle. In some contexts, such as particle physics, this trade-off can be attributed to the finite speed of light and the fact that it takes a certain period of time for the photons carrying information to reach the observer. In this time, the system might have undergone changes itself. Thus, the longer the light has to travel, the lower the temporal resolution. Technology Computing In another context, there is often a tradeoff between temporal resolution and computer storage. A transducer may be able to record data every millisecond, but available storage may not allow this, and in the case of 4D PET imaging the resolution may be limited to several minutes. Electronic displays In some applications, temporal resolution may instead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
