SNOTEL Elk Cabin, NM (Feb, 2017)

The basic SNOTEL station provides snowpack water content data via a
pressure-sensing snow pillow. It also collects data on snow depth, all-season
precipitation accumulation, and air temperature with daily maximums, minimums, and
averages. Many of the enhanced SNOTEL stations are also equipped to take soil
moisture and temperature measurements at various depths. The atmospheric and, where
installed, soil moisture and soil temperature measurements are generally reported
multiple times per day with some reporting hourly. Other sensors such as water
quality sensors can be added to any of the enhanced SNOTEL stations. System
performance is usually above 99%.

基础型SNOTEL站点通过压力感应式雪枕（pressure-sensing snow pillow）获取雪层含水量数据，同时还可采集雪深、全季降水累积量以及日最高、最低和平均气温数据。多数增强型SNOTEL站点还配备了多深度土壤湿度与温度监测设备。大气相关监测数据以及已部署的土壤湿度、土壤温度数据通常每日多次上报，部分站点可实现逐小时上报。增强型SNOTEL站点可加装水质传感器等各类辅助监测传感器。该系统的运行可用率通常可达99%以上。
