Snow Water Equivalent Modeling with the 'Delta.snow' and 'HS2SWE' Models and Empirical Regression Models

Snow water equivalent is modeled with the process based models 'delta.snow' and 'HS2SWE' and empirical regression, which use relationships between density and diverse at-site parameters. The methods are described in Winkler et al. (2021) , Magnusson et al. (2025) , Guyennon et al. (2019) , Pistocchi (2016) , Jonas et al. (2009) and Sturm et al. (2010) .

R-package with functions for Snow Water Equivalent Modeling with the $\Delta\text{SNOW}$ Model, the HS2SWE Model and some Empirical Regression Models.

Snow water equivalent can be modeled either with the process based models $\Delta\text{SNOW}$ and HS2SWE, or with empirical regression models, which use relationships between density and diverse at-site parameters. The $\Delta\text{SNOW}$ model is described in Winkler et al. (2021), the HS2SWE model is described in Magnusson et al., (2025), the empirical regression models in Guyennon et al. (2019), Pistocchi (2016), Jonas et al. (2009) and Sturm et al. (2010).
