title: Dataset: Direct Insertion Of Nasa Airborne Snow Observatory-Derived Snow Depth Time-Series Into The Isnobal Energy Balance Snow Model

description: This dataset is a companion to the submitted WRR publication entitled ‘Direct insertion of NASA Airborne Snow Observatory-derived snow depth time-series into the iSnobal energy balance snow model’. The file structure is organized as follows:


	<strong>ASO_50m_depth_surfaces</strong> - This folder contains the Airborne Snow Observatory lidar-derived snow depth products aggregated to 50m gridded spatial resolution. Each file is titled with a date such as ‘TB<em>YYYYMMDD</em>_SUPERsnow_depth.asc’. The coordinates are in UTM zone 11N and use the WGS84 coordinate system.
	<strong>static_grids</strong>
	
		Static grids are used in each of the subsequent folders and are not changed between years.
		init0000.ipw
		
			Initialization file to begin the model run. Contains the digital elevation model in band 1, surface roughness raster in band 2, and zeroed images of snow properties in bands 3-7.
		
		
		maxus.nc
		
			netCDF file of 72 separate images of maximum upwind slope for all upwind directions from 0 (north) to 355 degrees in 5-degree increments. Derived using Adam Winstral’s Sx algorithm.
		
		
		tuolx_dem_50m.ipw
		
			Digital elevation model from ASO snow-free acquisition aggregated to 50m gridded spatial resolution. Same information as band 1 in the init0000.ipw file.
		
		
		tuolx_hetchy_mask_50m.ipw
		
			Basin mask of the Tuolumne River Basin above Hetch Hetchy Reservoir. Out-of-basin cells denoted as 0, and in-basin cells denoted as 1.
		
		
		tuolx_vegheight_50m.ipw
		
			Vegetation height raster in meters. Derived from NLCD dataset of vegetation type..
		
		
		tuolx_vegk_50m.ipw
		
			Emissivity of the vegetation canopy. Derived from NLCD dataset of vegetation type.
		
		
		tuolx_vegnlcd_50m.ipw
		
			Vegetation type from the National Land Cover Database.
		
		
		tuolx_vegtau_50m.ipw
		
			Fractional transmissivity of the vegetation canopy. Derived from NLCD dataset of vegetation type.

The directories for each water year contain the configuration file for that year along with the vector meteorological data from measurement sites and site metadata in .csv format.
