title: Replicar los datos para: Snow accumulation patterns in a high mountain Andean catchment from optical tri-stereoscopic remote sensing

description: 1) DBSM_Data_RioYeso' = Automatic weather station (AWS) data from Yeso Embalse and Termas del Plomo meteorological stations (available from Chilean Water Directorate, 'Dirección General de Aguas' or 'DGA' http://www.arcgis.com/apps/OnePane/basicviewer/index.html?appid=d508beb3a88f43d28c17a8ec9fac5ef0), used to force a distributed blowing snow model of Essery et al. (1999) to derive spatial snow depth of the Rio del Yeso catchment, Chile. The format is as follows: {'Year','Month','Day','Hour','Incoming shortwave radiation (Wm2)','Incoming longwave radiation (Wm2)','SnowfallRate(mm/hr)','RainfallRate(mm/hr)','Air temperature (celsius)','Relative humidity (%)','Wind speed (m s-1)','Compass wind direction','Air pressure (hPa)'}; 2) 'snowHeightPleiadesREG' = A snow depth map (horizontal resolution 4m) derived from triplets of high resoution stereo optical satellite images (Pléiades) following the methodology of Marti et al. (2016). The snow depth map is derived for a high mountain catchment (Rio del Yeso) of the central Chilean Andes (see Burger et al., 2018). 3) 'L2_LiDAR_4m' = A LiDAR (Light detection and Ranging) spatial snow depth map at a horizontal resolution of 4 m. The data were captured by a Reigl VZ-6000 LiDAR scanner and generated from the difference of two constructed digital elevation models (DEMs) between the dates 13th September, 2017 (with snow) and 12th December, 2017 (without snow). 4) 'L2_Pleiades_SDLidar_NEW' = The Pléiades snow depth map as described in 2), extracted by the areas of LiDAR scan described in 3). 5) 'SnowDepthResults' = A folder containing a corrected and gap-filled Pléiades snow depth map ('SD_PleiadesCORR') and for comparison: 'SD_TOPO', a statistical estimation of snow depth using topographic parameters and the regression equation of Grünewald et al. (2013) and; The physically based estimates of snow depth using the DBSM model as in 1) without snow transport for the 4th September, 2017 ('SD_EXTP_Sep04') and 13th September, 2017 ('SD_EXTP_Sep13') and with snow transport for those dates ('SD_Wind_Sep04','SD_Wind_Sep13'). 6) 'rdyDEM' = An independent ASTER GDEM (https://asterweb.jpl.nasa.gov/gdem.asp) cut to the area of the study catchment (horizontal resolution = 30 m). 7) 'PlanetScope_20170907_TPK' = An stitched optical PlanetScope image of the catchment (horizontal resolution of 3.25 m) derived from access under the research and teaching iniative (planet.com).
