Improving estimates of snowpack water equivalent using double sampling / R.J. Rovansek, D.L. Kane, L.D. Hinzman.
Title: | Improving estimates of snowpack water equivalent using double sampling / R.J. Rovansek, D.L. Kane, L.D. Hinzman. |
Author(s): | Rovansek, R. J. Kane, D. L. Hinzman, L. D. |
Date: | [1993] |
In: | Eastern Snow Conference. Proceedings. ([1993]), Vol. 50th Annual Meeting ([1993]) |
Abstract: | Equations are presented to estimate average SWE and variance of estimate using double sampling, which refers to sampling snowpack in two ways: measuring depth at several points, and measuring depth and SWE at smaller number of points. This can yield estimate of SWE having lower variance than is possible by measuring SWE only. Equations presented here were tested during extensive snow surveys conducted on North Slope of Alaska. |
