FG or Background

Cristian Lussana edited this page Mar 24, 2021 · 1 revision

The background values are computed taking into account all observations inside an outer circle.

Available options are:

  • VerticalProfile. Estimate the background as a function of the observation elevations as done in the paper by Frei (2014). Optimized for temperature profiles in complex terrains.
  • VerticalProfileTheilSen. Estimate the background as a function of the observation elevations with the Theil-Sen linear regression (Wilks (2019)). If compared to VerticalProfile, this option implements a method that is more resistant to outliers in the data.
  • MeanOuterCircle. The background is constant and it is set to the mean value of the observations.
  • MedianOuterCircle. The background is constant and it is set to the median value of the observations.
  • External. The background values are given by the user.
