Antarctic Barometric Pressure

barometric pressure cycles

Barometric pressure changes can induce airflow in an open borehole or well screened in the vadose zone, thereby ventilating the soil surrounding the borehole. This paper presents an analytic model of the induced airflow and compares the predictions of the model with experimental measurements. This model may be useful for the design of passive soil vapor extraction as applied to the remediation ...

AN1326, Barometric Pressure Measurement Using Semiconductor Pressure Sensors

The most recent advances in silicon micromachining technology have given rise to a variety of low-cost pressure sensor applications and solutions. Certain applications had previously been hindered by the high-cost, large size, and overall reliability limitations of electromechanical pressure sensing devices. Furthermore, the integration of on-chip temperature compensation and calibration has al...

Barometric Pressure Variations Associated with Eastern Pacific Tropical Instability Waves*

Barometric pressure, surface temperature, and wind time series in the eastern equatorial Pacific are analyzed to determine if oceanic tropical instability wave (TIW) sea surface temperature variations cause barometric pressure gradients large enough to influence the atmospheric boundary layer. During the study period from April 2001 to September 2002, 11 TIWs propagated westward past 110!W, cau...

Work in Progress: Experiments on MEMS Barometric Pressure Sensors

This paper overviews findings, potential and limitations of a low-cost vertical distance measurement system, as regards lab research and experimental education on MEMS barometric pressure sensors, and future research directions are also recommended.
