Gary,

    I was interested in your comments copied below, because of a similar st=
udy I did about five years ago.  There I looked for atmospheric pressure fl=
uctuations associated with Hurricane Dennis--also using a vertical seismome=
ter (modified Sprengnether, the sensor of which is a fully-differential cap=
acitive position type).  The pressure sensor was also a fully differential =
capacitive type (differential in terms of both pressure across the diaphrag=
m and potential across the electrodes).  A paper describing the work was pu=
blished on arxiv at

Len Polucci on Nov. 7th. discussed the use of the Ashcroft differential air=
 pressure sensor. This device was just what I was looking for. I have built=
 an Infra-Sonic Atmospheric Air Pressure sensor. See http://sites.google.co=
m/site/seismicsensorinfo/infra-sonic-atmospheric-air-p

ressure-sensor    for details. The goal is to try to correlate atmospheric

pressure changes with vertical seismometer background noise.



Thank you Len for the info.
