Weather and environmentWMO siting practice, WIGOS metadata.
Weather and environment, inside Sensors & instruments: air temperature and humidity, atmospheric pressure, surface wind, precipitation and more. Every item is traced to its specification, from WMO-No. 8 Volume I (temperature, humidity) to WMO-No. 8 Volume I (atmospheric pressure), and runs on the open Observatory Protocol.

01What it is
Meteorology (WMO No. 8 classes).
Instruments placed in the air, water, ground and spectrum, from weather stations to seismometers, radars and cameras, with the calibration, metadata and quality control that make their readings evidence. Each technology below carries what it is, what we do with it, and the standard it is drawn against.

03On the grid
Every site joins one observing grid.
The open networks on the grid today, over real relief and the geodesic cells we count them into, filtered to the atmosphere domain this area serves. A site built here enrols into the same grid.
