"Extending the utility of space-borne snow water equivalent observations over vegetated
	areas with data assimilation"
Data last updated: J. Pflug (justin.pflug@nasa.gov) -- 12 Jul 2023

-domain_params.nc [Land Data Toolkit file]:
	- Static data for the modeling domain investigated in this study. Variables include:
		- lat: Latitude (degrees North, WGS84) for each model grid cell
		- lon: Longitude (degrees East, WGS84) for each model grid cell
		- ELEVATION: Domain elevation (m) based on the National Elevation Dataset (NED;
			https://gdg.sc.egov.usda.gov/Catalog/ProductDescription/NED.html)
		- LANDCOVER: Domain integer landcover map, based on the landcover map from
			IGBP/NCEP (e.g., http://www.eomf.ou.edu/static/IGBP.pdf)

The following files are spatial outputs on the grid specified by the lat/lon grid from 
	"domain_params.nc" above. Due to the large number of grid cells, files are saved in ascii format.

	- huc_basins.asc: Map of integers representing the grid cells that fell within each of the
		subbasins analyzed in this study. Basins are labeled as the following:
		- 1: Upper Colorado
		- 2: Great Basin
		- 3: Pacific Northwest
		- 4: California

	- *_DJF_SWE.asc: Maps of average winter (December, January, February) SWE for each simulation,
		rounded to the nearest mm. Filename prefixes represent the simulation. They are as follows:
		- NR: Nature run
		- OL: Open loop
		- DA1: Simulation with data assimilation, without the forest strategy
		- DA2: Simulation with data assimilation, with the forest strategy   
	- *_20190313_SWE.asc: Maps of SWE (rounded to the nearest mm) on Mar 13 2019. The file prefixes
		reference the simulation and are identical to the previous dataset.

The remainder of the files are temporal outputs aggregated across the grid cells that fall within each
	of the huc basins (e.g., from "huc_basins.asc"). Each entry represents variables at daily 
	timesteps between 1 October 2018 and 15 Aug 2019.
	- *A*_temporal_*B*_HUC*C*.asc --> wildcards represent the following:
		- *A*: The simulation (NR, OL, DA1, or DA2)
		- *B*: The output variable:
			- SWE_tavg: SWE averaged at daily timesteps across all grid cells within a given
				basin. Outputs are rounded to the nearest mm
			- Qtot_tavg: Total runoff summed at daily timesteps across all grid cells within
				a given basin. Outputs are rounded to the nearest m
		- *C*: The subbasin, identical to those listed above (e.g., Upper Colorado, California, etc.)
