Technical Report WRD92039 Viewed at 15:07:17 on 29/07/2010 Page 171 of 192. (i) select a reference time TO, at which both the actual head and barometric pressure are known; (ii) convert the set of barometric pressure readings to one of changes in barometric pressure from that at TO, by subtracting the value at TO from the entire set (as (2) above); (iii) find the subtracting from the "Process" barometrically corrected head by the set of barometric pressure changes set of logged head readings. (The option can automatically interpolate values of the barometric pressure changes for those times at which there are head values) The procedure for applying barometric corrections to a set of logged draVldown data is the same as outlined above, except that the set of barometric pressure changes must be added. to the SElt of logged head readings. See also example 4.1 below.
