Now, today, and the week
522 instruments still reporting in North Dakota, across 5 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 now104 instruments
Road weather towers
45 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.
Data-collection platforms
17 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.
measured daily418 instruments
Volunteer precipitation and snow observers
326 instruments/once a day
precip, snowfall, snow depth
The same measurement a cooperative observer makes, from many more gardens. North Dakota publishes 326 of these against 92 cooperative observers, so on most days it is the densest picture of what is on the ground that exists.
Cooperative observers
92 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.
