Atmosphere and Air Data Measurement topics include: Atmosphere characteristics, air vertical development, standard atmospheric model, air data and height measurement, airflow characteristics and airspeed measurements, air data computers, mach number and air temperature measurements.

Here are some common methods and parameters used to measure and analyze air:
Temperature: A thermometer can be used to measure temperature, such as a mercury-in-glass thermometer or a digital thermometer.
Pressure: A barometer can be used to measure atmospheric pressure. There are three basic types of barometers: liquid, mercury, and aneroid.
Humidity: A hygrometer or psychrometer can be used to measure humidity, or the amount of water vapor in the air.
Other measurements: Other atmospheric measurements include winds, dew point, moisture, radiation, visibility, cloud heights, lightning, gaseous composition, aerosols, and precipitation. 

Air data systems (ADS) onboard aircraft can compute air data, including:
Barometric altitude
Ambient air temperature
Environmental wind
Aircraft flight speed relative to the air 

Air data systems also provide information on quantities such as:
Pressure altitude
Vertical speed
Calibrated airspeed
True airspeed
Mach number
Static air temperature
Air density ratio
