ttlight: A function to process and plot TreeTalker spectrometer data.

In EnricoTomelleri/ttalkR: For download and standard processing of TreeTalker data

A function to process and plot TreeTalker spectrometer data.

Description

The function makes use of data frames created by the "ttScrape()" function. It processes data from AMS chips, Model: AS7262 (Visible range), AS7263 (Near Infra-Red range) sensors. It filters, aggregate to daily values and plot spectrometer data from a TreeTalkers mesh. The filtering is based on solar geometry base on provided coordinated (lat, lon). The function doesn't account for topography. The filtered data include measurements with the sun position from -30 to + 30 degrees from the geographic South.

Usage

ttLight(mydata_49, lat, lon, wavelength, plot_label)

Arguments

mydata_49	a ttScrape object
lat	central latitude of the measurement plot
lon	central longitude of the measurement plot
wavelength	it identifies the spectral band to be plotted. Options are: 450, 500, 550, 570, 600, 650, 610, 680, 730, 760, 810 and 860 nm
plot_label	"all_in_one": all the treetalkers in a plot "split": each treetalker in a different panel "none": it doesn't plot
