swe.st10 {nixmass} | R Documentation |
The Sturm model parametrizes bulk snow density with day of the year and a snowclass.st10. It was trained on historical snow height - density - SWE data from the United States, Canada, and Switzerland.
swe.st10(data,snowclass.st10)
data |
A data.frame of daily observations with two columns named date and hs referring to day and snow height at that day. The date column must be a character string with the format |
snowclass.st10 |
Must be one of the following character strings: "alpine","maritime","prairie","tundra","taiga". |
swe.st10
This model converts snow height to SWE using snow height, day of year and station location (from which a climate class of snow can be inferred. The day of year (DOY) is the day-number of in the season 1.10. - 30.6. The 1.10. refers to DOY = -92. The 1.2. would be DOY = 32, while 15.11. would be DOY = -47. The snowclass.st10 must be one out of the character strings "alpine","maritime","prairie","tundra" and "taiga". For the Alps probably "alpine" would be the most appropriate climate classification.
Non computable values are returned as NA.
A vector with daily SWE values in mm.
