1. A method of estimating the LFG generation rate of a landfill located at a landfill site, comprising the steps ofa. obtaining a time history record of atmospheric pressure that is representative of atmospheric pressure at a surface boundary of the landfill, b. measuring gas pressure at a selected subsurface location at the landfill site over a time period that is included in the time history record of step a, and c. using the atmospheric pressure of step a and the measured gas pressure of step b to estimate the LFG generation rate of a portion of the landfill.
