Atmospheric Temperature Fields Measurements

Measurements > Atmosphere > Atmospheric Temperature Fields
With humidity, atmospheric temperature profile data are a core requirement for weather forecasting and are coordinated within the framework of CGMS (The Coordination Group for Meteorological Satellites). The data are used for numerical weather prediction (NWP), for monitoring inter-annual global temperature changes, for identifying correlations between atmospheric parameters and climatic behaviour, and for validating global models of the atmosphere.
Detailed MeasurementDescriptionInstrumentsTimeline
Air temperature (near surface)Air temperature at a known height above the surface with the height specified in the metadata - Measuring Units K, Uncertainty Units K
2 instruments
Timeline for Air temperature (near surface)
Atmospheric pressure (over land surface)Pressure caused by the weight of the atmosphere. At sea level it has a mean value of one atmosphere but reduces with increasing altitude. Conventionally measured at 2 m height. [Unit of measurement - hPa]
5 instruments
