Lidar-derived snow depth maps along the Chilean Extratropical Andes, winter 2018

All the files included here contain the data produced for the manuscript "Spatial distribution and scaling properties of lidar-derived snow depth in the extratropical Andes", submitted for possible publication in Water Resources Research. Lidar measurements for snow-covered conditions were conducted on September 4th, August 9th, and October 25th 2018 in Tascadero, Las Bayas and Valle Hermoso, respectively. Each data acquisition was conducted using a Riegl VZ6000 long range scanner on dates with and without snow, using an angular resolution of 0.01°.

Lidar-derived maps are contained in the following files:

SiteName_SD_TPI.txt (SiteName: Tascadero, Las Bayas, VH East or VH West).

Where the file structure is as follows:

X,Y,Z,SD,SLP,NOR,TPI04,TPI07,TPI15,TPI20,TPI30,TPI40,TPI50

where Z is bare earth elevation (m a.s.l.), SD is snow depth, SLP is slope (°), NOR is northness (°) whereby 180 = north facing and 0 = south facing, TPIXX is the Topographic Position Index (TPI) computed for a search distance of XX m, whereby positive differences are convex landforms, and negative is concave. The magnitude of TPI indicates the scale of the relative concavity/convexity.

Variogram results are contained in files .rsav with the following nomenclature:

SiteName_X_TypeOfVariogram.rsav

Where X can be SD (snow depth) or Z (bare earth topography), and the type of variogram can be omnidirectional or directional.
