Now, today, and the week
962 instruments still reporting in Montana, across 7 networks, each one with the kind of measurement it makes and how often it makes it. Open a place below to see which of them stand near it.
measured now455 instruments
Data-collection platforms
288 instruments/hourly
temp, wind, gust, humidity, pressure
Shore stations, fire weather stations and river gauges on one identifier. Most of them measure the river and are never offered here; the ones that are published air temperature and wind. A platform that was quiet when the catalogue was built is still listed, because it remains registered with its network. It is the only shoreline wind this service carries.
Road weather towers
112 instruments/minutes
temp, pavement temp, wind, visibility, precip
Air temperature, pavement temperature, wind and visibility, placed where the road closes. The right instrument for a blowing-snow answer and almost nobody uses it well.
Airport surface observations
42 instruments/minutes
temp, wind, gust, visibility, precip, pressure
The backbone. Individual sensors fail and the station does not, so every reading is published with the age of the observation beside it.
Soil climate stations
8 instruments/hourly
temp, humidity, soil temp, soil moisture
Air and soil together: temperature and moisture measured in the ground at depth, hourly, mostly on farms and research land.
Climate reference stations
5 instruments/hourly
temp, humidity, wind, solar, precip
The national reference: triple sensors for temperature and precipitation, sited well away from buildings and paving, and kept to one standard across the country. The yardstick the other instruments are measured against.
measured daily507 instruments
Volunteer precipitation and snow observers
300 instruments/once a day
precip, snowfall, snow depth
The same measurement a cooperative observer makes, from many more gardens. Montana publishes 300 of these against 207 cooperative observers, so on most days it is the densest picture of what is on the ground that exists.
Cooperative observers
207 instruments/once a day
snowfall, snow depth, precip, high, low
A person, a board and a ruler, in the morning. It cannot say what is falling right now and it is the best answer to how much is on the ground.
