What relative humidity, dew point, absolute humidity and mixing ratio are, how temperature and pressure distort the reading, and why dew point is…
Technical note
Radiosondes measure critical atmospheric variables with accuracy and precision that cannot be obtained with other meteorological observations. Radiosondes are unique instruments as they provide continuous, detailed profiles from the ground to altitudes of 30 km and above. The quality and reliability of the measurements are essential. Even small inaccuracies in the profiles can prevent the forecaster from observing critical details and making correct conclusions.
The chapters in this document provide information on the importance of radiosonde measurement accuracy, and how accuracy helps to successfully forecast high impact weather. Graphs, tables, and case study summaries illustrate how correct or incorrect observations of temperature inversion layers, ice forming layers, humidity, and other atmospheric properties can change a forecast in various weather situations.
