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.

What is measuring in Virginia
1,403 instruments still reporting in Virginia, across 4 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.

Data-collection platforms
25 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 daily1,308 instruments
Volunteer precipitation and snow observers
1,212 instruments/once a day
precip, snowfall, snow depth
The same measurement a cooperative observer makes, from many more gardens. Virginia publishes 1,212 of these against 96 cooperative observers, so on most days it is the densest picture of what is on the ground that exists.
Cooperative observers
96 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.
