Abstract

This resource is part of the larger SnowClim Dataset (https://www.hydroshare.org/resource/acc4f39ad6924a78811750043d59e5d0/). This resource contains present-day climate metrics. Climate metrics were created by downscaling outputs of the Weather Research and Forecasting Model (WRF; Rasmussen and Liu, 2017) for the present-day period (1 Oct 2000 to 30 Sep 2013) using a combination of local lapse rates and terrain corrections for solar radiation as described in Lute et al., (in prep). Climate metrics are available on a ~210 m grid for the western United States in both netCDF and GeoTiff formats.

Additional information is available in:
Lute, A. C., Abatzoglou, J., and Link, T.: SnowClim v1.0: high-resolution snow model and data for the western United States, Geosci. Model Dev., 15, 5045–5071, https://doi.org/10.5194/gmd-15-5045-2022, 2022.

Summary:
------------------------------------------------------------------------
This directory contains climate metrics for the present-day period and
represents a subset of the SnowClim Dataset
(https://www.hydroshare.org/resource/acc4f39ad6924a78811750043d59e5d0/).
The SnowClim Dataset was developed following the methods presented in
Lute et al., (in prep). The present-day climate data was created by
downscaling 4 km climate forcings from the Weather Research and
Forecasting (WRF) model (Rasmussen and Liu, 2017) over a thirteen year
period (1 Oct 2000 to 30 Sep 2013). Downscaled climate data was
summarized into climate metrics at ~210 m spatial resolution for the
western US. Additional details about the downscaling approach can be
found in Lute et al., (in prep).


File Organization:
------------------------------------------------------------------------
Climate metrics are available in separate files. For accessibility,
metrics are available in both GeoTiff and netCDF format. The suffix
'_CTRL' indicates that the data represents conditions under the control
scenario (aka present-day climate). Metrics with values for each month
have values for January through December.


Metrics:
------------------------------------------------------------------------
- downwelling shortwave

	units: W m-2

	Monthly mean downwelling shortwave radiation at the surface,
	downscaled from WRF (Rasmussen and Liu, 2017; which accounts for
	cloud cover) using the R insolvent package to 	correct for
	aspect, self-shading, and shading by adjacent terrain.

- minimum air temperature (tmin)

	units: °C

	Monthly mean of daily minimum 2m air temperatures, downscaled from
	WRF (Rasmussen and Liu, 2017) using local lapse rates.

- maximum air temperature (tmax)

	units: °C

	Monthly mean of daily maximum 2m air temperatures, downscaled from
	WRF (Rasmussen and Liu, 2017) using local lapse rates.

- mean air temperature (tmean)

	units: °C

	Monthly mean of daily mean 2m air temperatures, downscaled from WRF
	(Rasmussen and Liu, 2017) using local lapse rates.

- mean dew point temperature (tdmean)

	units: °C

	Monthly mean of daily mean 2m dewpoint temperatures, downscaled from
	WRF (Rasmussen and Liu, 2017) using local lapse rates.

- precipitation (ppt)

	units: meters (m)

	Monthly total precipitation, downscaled from WRF (Rasmussen and Liu,
	2017) using local lapse rates and bias corrected using PRISM
	precipitation data (PRISM Climate Group, 2015).

- number of temperature sign changes (tschange)

	units: count

	Annual number of times that temperature (°C) changes sign.
	Calculated from 4-hourly air temperatures downscaled from WRF
	(Rasmussen and Liu, 2017) using local lapse rates.
