Description

50 year ground snow load estimates at 415 measurement locations in locations in and around the state of Utah. Used as part of the 2018 Utah snow load study.

Usage

1

Format

A data frame with 415 rows and 10 variables:

STATION

The National Weather Service COOP, or Natural Resource conservation service SNOTEL station identifier.

STATION_NAME

The character name of the station.

STATE

Two character state abbreviation of the measurement location.

LONGITUDE

Longitude coordinate position.

LATITUDE

Latitude coordinate position.

ELEVATION

Elevation of the measurement location (meters).

YRS

The number of years of recorded load maximums. This is effectively the sample size of the 50 year estimate.

maxobs

The maximum snow load observation from the period of record (kpa).

yr50

The estimated design (i.e. 50 year) ground snow load (kpa).

HUC

The United States Geological Survey 8 digit hydrologic unit code.

Details

This dataset contains 279 (192 COOP, 87 SNOTEL) Utah stations with an additional 136 stations (103 COOP, 33 SNOTEL), all located within 100 km of the Utah border. 50 year estimates were obtained by fitting a log-normal distribution to the annual maximum snow loads (by water year, not calendar year) via maximum likelihood estimation and extracting the 98th percentile.
