IHMODTM gives the user a choice between running the model in deterministic (point value parameters as was in IHMOD 1.0) or in Monte Carlo Simulation mode, with choices of distributions of parameter values right in MS Excel with no other software needed. An IHMOD Support File is also available. It includes useful information about IHMODTM. A spreadsheet tab to estimate liquid spill pool generation rates via the Hummel-Fehrenbacher equation, units of measure conversion tool, examples of generation rate estimation, a “Bootstrap” procedure tool, a summary of approaches to estimate ALPHA for the exponentially decreasing emission rate models, and some links to other resources. Please note that the support file is evolving and will be updated periodically with new information. Check back here for updates.
