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:
- ASO_50m_depth_surfaces - 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 ‘TBYYYYMMDD_SUPERsnow_depth.asc’. The coordinates are in UTM zone 11N and use the WGS84 coordinate system.
- static_grids
- 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.
