About FFP Overlay
This Python application is a wrapper for the Kljun et al. 2015 flux footprint prediction (FFP) model. It allows users to incorporate spatial analysis in the FFP processing pipeline while speeding up FFP calculation parallelizing the processing.

Example Output
Given half-hourly turbulence conditions and metadata for a site, this wrapper will calculate the FFP on a per-time-step basis, and output FFP contours over desired intervals in this web-map format. If provided a landscape classification map, the program will also overlay each timestep’s footprint with the map. This allows the user to estimate the relative source contrition of different ecosystem components in some heterogeneous ecosystems. Figure 1 shows an example of the web map output for the Burns Bog 2 EC station. Figure 2 gives an example of outputs that can be produced when a basemap ecosystem classification map is provided.
