This repository mainly contains two scripts:

• One script for data extraction from the EC-tower processed data in order to support the footprint-area calculation
• One script from Dr. Ayman Nassar for footprint-area calculation (Slight changes in algorithm have been made based on Ayman's original script)

This simple script used in python aims at extracting information from the EC tower (processed) data, a part of the GRAPEX project. The product from this programm can be used to generate the corresponding footprint area, and can also (conveniently) used for TSEB modeling verification.

• Running this script successfully, it requires an EXCEL table providing searching index in order to find the correct record from the EC-tower processed table. Year, month, day, hour, and minute are keys to locate the record in the EC-tower after processed data (table).
• "Request_Demo.xlsx" is a demo data from users' request.
• Manual work are still required, since the processed tables from the GRAPEX project are not exactly the same. Thus, slight modification for this script or the original table (not recommend) is required accordingly.

Please refer Ayman's published paper:
To what extend does the Eddy Covariance footprint cutoff influence the estimation of surface energy fluxes using two source energy balance model and high-resolution imagery in commercial vineyards?

Details about this repository (or how to run those python programs) can be found in Footprint area generating based on eddy covariance records either on the HYDROSHARE platform or the "Manual.pdf" in this repository. This repository is just a copy of the work published on the HYDROSHARE platform.

Please cite the paper below when you are using any script in this repository.
