Aircraft Meteorological Data Relay (AMDAR) is a program initiated by the World Meteorological Organization.AMDAR is used to collect meteorological data worldwide by using commercial aircraft.
[268] [269] With the weather station at Zürichberg reporting its highest ever value since the station was established in 1949. [ 270 ] Other high pressures in Switzerland are given as 3–4 March 1990 at Zurich Airport of >1047 hPa [ 271 ] and 29 January 1989 at Schaffhausen of 1047.2 hPa, which was the highest pressure in the country since ...
A LLWAS master station polls each remote station every system cycle (nominally every ten seconds) and provides prevailing airport wind averages, runway specific winds, gusts, may set new wind shear alerts or microburst alerts and reset countdown timers of elapsed time since the last alert.
Data dissemination is usually via an automated VHF airband radio frequency (108-137 MHz) at each airport, broadcasting the automated weather observation. This is often via the automatic terminal information service (ATIS). Most automated weather stations also have discrete phone numbers to retrieve real-time observations over the phone or ...

SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting weather observations made by staffed and automated weather stations. SYNOP reports are typically sent every six hours by Deutscher Wetterdienst on shortwave and low frequency using RTTY .
ASOS sensors, located at Salinas, California. Surface weather observations have traditionally been taken at airports due to safety concerns during takeoffs and landings. The ICAO defines the International Standard Atmosphere (also known as ICAO Standard Atmosphere), which is the model of the standard variation of pressure, temperature, density, and viscosity with elevation/altitude in the ...
