The FAA completed an upgrade of the 230 FAA owned AWOS and former automated weather sensor systems (AWSS) systems to the AWOS-C configuration in 2017. [3] The AWOS-C is the most up-to-date FAA owned AWOS facility and can generate METAR/SPECI formatted aviation weather reports. The AWOS-C is functionally equivalent to the ASOS. [4]

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 . Data is collected by the aircraft navigation systems and the onboard standard temperature and static pressure probes.

The standard mast heights used with automatic weather stations are 2, 3, 10 and 30 meters. Other sizes are available, but typically these sizes have been used as standards for differing applications. [1] The 2-meter (6.6 ft) mast is used for the measurement of parameters that affect a human subject. The mast height is referenced to head height.
The air data module is a gas pressure sensor which converts mechanical forces created by gas pressure into digital signals that can be carried to the air data reference unit. ADMs generally have a maintenance bus and communication bus, and a connector on the housing for a pressurized gas line that is connected to the pitot tube or static ports.
Meteorological instruments (or weather instruments), including meteorological sensors (weather sensors), are the equipment used to find the state of the atmosphere at a given time. Each science has its own unique sets of laboratory equipment.
On the top right corner of the model for a surface weather map is the pressure, showing the last two integer digits of the pressure in millibars, or hectopascals, along with the first decimal. For instance, if the pressure at a certain location is 999.7 hPa, the pressure portion of the station model will read 997.
