Does anyone have a spreadsheet that reproduces how Isodat applies an H3+ calculation to continuous flow data? I have read the Alex Sessions papers and can see from the archives that Isodat does something a bit strange but wondered if anyone has this either documented or in a spreadsheet? As an alternative, is there an Open Source program that will do H3+ factor calcs - both calculation of H3+ factor and application to CF data?
Thanks,
Simon
