calculateFootprint: Minimum argument footprint calculation

In FREddyPro: Post-Processing EddyPro Full Output File

Description

A wrapper function for quick calculation of the average footprint for a specific period of time with minimum required arguments

Usage

calculateFootprint(df, displacement, stability = NULL, fetch = 500,
grid = 200, height, lowerDay = NULL, upperDay = NULL)

Arguments

df	The data frame to use
displacement	Displacement height in meters.
stability	Integer used to mask the data for stability. 1=Unstable, 2=neutral, 3=stable conditions.
fetch	The upwind distance over which you want the calculation domain to extend. Note that the footprint will be normalized to that domain so footprints that extend well beyond the domain will be overrepresented in
grid	The total calculation grid size. The default is 200 which would mean the footprint would be represented in a 200x200 array corresponding to dimensions of two times the fetch on each side of the grid.
height	The z-d height of the flux system
lowerDay	The lower limit of the period to calculate the footprint
upperDay	The upper limit of the period to calculate the footprint

Value

Returns a list object of a footprint similar to that of the function Average

Examples

## Load the data
data(fluxes)

## Clean fluxes
fluxes=cleanFluxes(fluxes,sdCor=TRUE,sdTimes=3,timesList=3,distCor=TRUE,
                   thresholdList=list(H=c(-100,1000),LE=c(-100,1000)))	

## Quick calculation of footprint
ftp=calculateFootprint(fluxes,17.42,stability=1,fetch=500,grid=200,height=33,
lowerDay=150,upperDay=151)

## You can also use the plot.footprint function of FREddyPro to plot the result
plotFootprint(ftp)
