AmbientWeather.net provides live data monitoring, forecasts and weather maps, graphs and historical data, email and text alerts, and API, IFTTT, Amazon Alexa and Google Home integration. In 2019, Ambient Weather was acquired by Nielsen-Kellerman, a manufacturer of weather stations, ballistics and weather instruments, and sports performance ...
Ambient Devices ran a data network called "Ambient Information Network" [9] that sends weather, stock market activity, sport scores, energy pricing and usage using a paging network that utilizes encoded FM radio stations to send out a data broadcast signals to Ambient devices. Ambient stopped transmitting these signals in 2019, rendering ...
The distinguishing features that classify a network of weather stations as a mesonet are station density and temporal resolution with sufficiently robust station quality. Depending upon the phenomena meant to be observed, mesonet stations use a spatial spacing of 1 to 40 kilometres (0.6 to 20 mi) [ 6 ] and report conditions every 1 to 15 minutes.
The temperature of the air near the surface of the Earth is measured at meteorological observatories and weather stations, usually using thermometers placed in a shelter such as a Stevenson screen—a standardized, well-ventilated, white-painted instrument shelter. The thermometers should be positioned 1.25–2 m above the ground.
By 1945, the United States Army Air Forces constructed 900 weather stations, of which more than 600 were stationed outside the United States. Weather stations were also transferred to operations of The Signals Corp. [ 2 ] In order to build an all-weather airfield, an area must be cleared of trees and other obstructions using machinery such as ...
Most automated weather stations also have discrete phone numbers to retrieve real-time observations over the phone or through a modem. In the United States, the AWOS/ASOS data acquisition system (ADAS), a computer system run by the FAA, polls the systems remotely, accessing the observations and disseminating them worldwide electronically in ...
The present weather sensor (PWS) is a component of an automatic weather station that detects the presence of hydrometeors and determines their type (rain, snow, drizzle, etc.) and intensity. It works on a principle similar to a bistatic radar , noting the passage of droplets, or flakes, between a transmitter and a sensor.
It forms part of a standard weather station and holds instruments that may include thermometers (ordinary, maximum/minimum), a hygrometer, a psychrometer, a dewcell, a barometer, and a thermograph. Stevenson screens may also be known as a cotton region shelter, an instrument shelter, a thermometer shelter, a thermoscreen, or a thermometer screen.
