Snotel

The SNOTEL network is composed of over automated data collection sites located in remote, high-elevation mountain watersheds snotel the western U. They are used to monitor snowpack, precipitation, snotel, temperature, and other climatic conditions. A typical SNOTEL remote site consists of measuring devices and sensors, an equipment shelter for the radio telemetry equipment, and an antenna that also supports the solar panels used to keep batteries charged. A snotel sensor configuration includes a snow pillow, a storage precipitation gage, and a temperature sensor, snotel.

While most weather stations are located at airports, most skiers and snowboarders enjoy the powder in the high mountains far from official airport weather stations. These sites are primarily focused on measuring both snow depth and the amount of water contained in the snow. Most skiers want to know the depth of the snow and how much new snow has fallen. Unfortunately, this is the measurement most prone to error. The snow depth sensor shoots a beam down toward the snow, and this beam is then reflected back up. A piece of simple electronics measures the time it takes for the beam to return to the sensor and calculates the snow depth and change in snow depth. Errors arise because the reflection of the beam off the snow surface is often inconsistent since snow is mostly made up of air pockets and not a solid layer of crystals.

Snow depth about April Hourly measurements provide resources managers with a continuous estimate of the amount of water contained in snowpack. Temperature and precipitation data recorded at SNOTEL sites also help resource managers understand local conditions at the remote sites. This information is valuable for estimating the rate of snowmelt. For each station, the SNOTEL Data Viewer provides one-click access to station information, tables showing 30 days of daily data or 7 days of hourly data, water year year-to-date charts showing accumulated precipitation, and other custom reports. Resource managers and flood forecasters access SNOTEL snow telemetry data to monitor temperature, precipitation, and the amount of water stored as snowpack at remote mountain sites across the West.

Federal government websites often end in. The site is secure. The Snow and Water Interactive Map displays both current and historic hydrometeorological data in an easy-to-use, visual interface. The information on the map comes from many sources. Other data sources include precipitation, streamflow, and reservoir data from the U. Information supplied by the map is updated three times daily.

Errors arise because the reflection of the beam off the snow surface is often inconsistent since snow is mostly made up of air pockets and not a solid layer of crystals. Use the snow depth data cautiously. A more trustworthy measurement is called Snow Liquid Equivalent SWE , which shows the amount of liquid that would be present if you melted a column of snow. The way that SWE is measured is truly ingenious.

The Interactive Map has two regions: the map display on the left and the map controls on the right. You use the map controls to determine both the display mode and the types of data and stations to show on the map. To help you get started with the Interactive Map, here are links to predefined maps organized by data type. After opening a map, you can zoom to your area of interest, customize the map, and then bookmark the URL to save your settings.

Resource managers and flood forecasters access SNOTEL snow telemetry data to monitor temperature, precipitation, and the amount of water stored as snowpack at remote mountain sites across the West. While a 95 percent response to a system-wide poll is the standard, over 99 percent is common. While most weather stations are located at airports, most skiers and snowboarders enjoy the powder in the high mountains far from official airport weather stations. Snow Reports Trip Planning Magazine. The Snow and Water Interactive Map displays both current and historic hydrometeorological data in an easy-to-use, visual interface. SNOTEL stations also collect data on snow depth, all-season precipitation accumulation, and air temperature with daily maximums, minimums, and averages. A piece of simple electronics measures the time it takes for the beam to return to the sensor and calculates the snow depth and change in snow depth. A variety of calculations can be made on any sensor channel. Use the snow depth data cautiously. Show current conditions for stations, basins or both. Alaska and the Arctic. Retrieved Main Navigation. Temperature and precipitation data recorded at SNOTEL sites also help resource managers understand local conditions at the remote sites.

The sites are generally located in remote high-mountain watersheds where access is often difficult or restricted. Access for maintenance by the NRCS includes various modes from hiking and skiing to helicopters. Some sites also measure snow depth, soil moisture and temperature, wind speed, solar radiation , humidity , and atmospheric pressure.

Does elevation affect temperature? Meteor Burst. Scientists correlate the amount of anti-freeze forced out of the bladder with the weight of the snow above. Automatic measuring devices in the shelter house convert the weight of the snow into an electrical reading of the snow's water equivalent -- that is, the actual amount of water in a given volume of snow. Hidden category: Commons category link is on Wikidata. SNOTEL stations also collect data on snow depth, all-season precipitation accumulation, and air temperature with daily maximums, minimums, and averages. Aerial markers with these sensors are called Snolite sites. System performance has increased over the years, mainly due to a better understanding of meteor burst communication characteristics and improved equipment. The National Water and Climate Center now provides similar information in an updated format by state and content. The Snow and Water Interactive Map displays both current and historic hydrometeorological data in an easy-to-use, visual interface. Use the Snow and Water Interactive Map. Most skiers want to know the depth of the snow and how much new snow has fallen. A standard sensor configuration includes a snow pillow, a storage precipitation gage, and a temperature sensor.
