Auxiliary Data Processing

The following software and packages are generally designed to process/visualize/analyze ancillary data that are often collected at the flux tower site or are relevant in analyzing flux data.

bigleaf

  • https://bitbucket.org/juergenknauer/bigleaf
  • R package for the derivation of physical and physiological bulk ecosystem properties from eddy covariance data
  • functions for calculating surface conductance, aerodynamic conductance, decoupling, surface temperature and humidity, potential evapotranspiration, intrinsic water-use efficiency, bulk intercellular CO2 concentration, etc.

Metvurst

  • https://github.com/tim-salabim/metvurst
  • The package focuses on visualizing large amounts of hourly environmental data
  • See examples e.g. here:

CuBI height

  • http://taronakai.wixsite.com/micrometeorology-en/cubi-height
  • Calculation of Cumulative Basal Area Inflection (CuBI) height. CuBI height is the representative canopy height of a forest stand determined as the height of the inflection point of a sigmoid-shaped relationship between tree height and cumulative basal area.
  • Available as R and Matlab software.

Baseliner

Landflux tools

  • http://landflux.org/Tools.php
  • Provides various Excel sheet-based tools mostly with ecophysiological relevance.
  • Contains sheets for A/Ci Curve Fitting, Pressure/volume curve-fitting, Photosynthetic Light Response curve fitting, Keeling Plot Curve Fitting, Leaf Energy Balance,  Two-Pool Decomposition Model 4.0, Uncertainty in Partitioning Using Two-Source Mixing Models, Green Fraction from Digital Images, Leaf Transpiration Calculator
