Instrumentation and Measurement of Atmospheric Pressure

Instrumentation and Measurement of Atmospheric Pressure
  • List common units used for pressure and the basis for each unit.
  • Summarize the use of the ideal-gas law for calculating pressure from other state variables of the atmosphere and describe the use of the hydrostatic and hypsometric equations.
  • Apply Dalton’s law to express the composition of air in terms of partial pressures and mixing ratios.
  • Outline the key steps in calibrating a pressure sensor.
  • Estimate the precision and uncertainty of pressure measurements required for pressure analyses.
  • Differentiate among the different types of instruments used to measure pressure.
  • List and identify the components of a pressure sensor and describe how each component can affect the measurement.
  • Determine the best instrument to measure pressure based on a set of requirements.
