FFT and Soil Temperatures

R Marksown Shiny script to model sub-surface soil temperatures using a simple heat-transfer model coupled with FFT.

This work is a clean-up of a workshop I presented on using R in ecological modeling. It describes FFT and then uses it to model soil temperatures at depth. This demonstration is based on work from:
