--- title: "Weather and environment: Sensors & | Nexus Observatory" description: "Weather and environment, inside Sensors & instruments: air temperature and humidity, atmospheric pressure, surface wind, precipitation and more." url: https://observatory.global/sensors/weather-and-environment/ publisher: Nexus Observatory Inc. updated: 2026-10-28 --- [Nexus Observatory](https://observatory.global/) / [Sensors & instruments](https://observatory.global/sensors/) / **Weather and environment** # WMO 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. [Plan with us](https://observatory.global/contact/) Architecture [The protocol](https://observatory.global/protocol/specification/) **Technologies**: 9 **At the frontier**: 0 **Protocol functions**: 3 of 8 **Industries served**: 21 Reference design, drawn to scale · drag to turn · hover a part **01** What 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. In situ sensors and instruments ### Air temperature and humidity Ventilated, shielded thermometers and hygrometers sited and exposed to WMO practice. We design, integrate, deploy, operate, maintain and support. WMO-No. 8 Volume I (temperature, humidity) In situ sensors and instruments ### Atmospheric pressure Barometers for weather, altimetry correction and storm surge analysis. We design, integrate, deploy, operate, maintain and support. WMO-No. 8 Volume I (atmospheric pressure) In situ sensors and instruments ### Surface wind Cup, vane and ultrasonic anemometers at standard heights with exposure corrections. We design, integrate, deploy, operate, maintain and support. WMO-No. 8 Volume I (surface wind) In situ sensors and instruments ### Precipitation Weighing, tipping-bucket and optical gauges with wind shields, including solid precipitation. We design, integrate, deploy, operate, maintain and support. WMO-No. 8 Volume I (precipitation) · EN 17277 (rainfall intensity instruments) In situ sensors and instruments ### Radiation and sunshine Pyranometers, pyrheliometers, pyrgeometers and sunshine recorders for energy and climate. We design, integrate, deploy, operate, maintain and support. ISO 9060:2018 (pyranometer classification) · ISO 9847 (field pyranometer calibration) · WMO-No. 8 Volume I (radiation) In situ sensors and instruments ### Visibility, cloud and present weather Forward-scatter visibility sensors, ceilometers and present-weather sensors for aviation and roads. We design, integrate, deploy, operate, maintain and support. WMO-No. 8 Volume I (visibility, clouds, present weather) In situ sensors and instruments ### Siting classification Classes for the exposure of each instrument so data users know how representative a site is. We design. WMO-No. 8 siting classifications for surface observing stations · ISO 19289:2014 In situ sensors and instruments ### Automatic weather stations Integrated stations with loggers, power and telemetry, run unattended for years. We design, integrate, deploy, operate, maintain and support. WMO-No. 8 Volume III (automatic weather stations) In situ sensors and instruments ### Cryosphere: snow, ice and permafrost Snow depth and water equivalent, ice thickness and ground temperature profiles. We design, integrate, deploy, operate, maintain and support. WMO-No. 8 Volume II (cryospheric variables, 2024 edition) **02** Architecture ## Where it sits, and what it speaks. Weather and environment draws on 1 domain and 8 layers of the spectrum; the highlighted layers carry this area. It speaks 3 of the protocol's 8 core functions. Meteorology (WMO No. 8 classes) 10 Air quality and atmospheric composition 7 Hydrology and water 7 Ocean and coastal 7 Seismic, geodetic, geomagnetic and radiation 8 RF, acoustics, cameras and radar 9 Calibration, metadata and quality control 7 Frontier and research 6 01**Join** Identity, attestation quote, signed policy. 02**Admit** Admitted for a stated scope, nothing wider. 03**Describe** What, where, how and by whom, with calibration. 04**Time** One clock across the grid, with its error bound. 05**Observe** Every value with quality and provenance. 06**Qualify** Tested against the specification, state on record. 07**Federate** Signed exchange across grids and trust domains. 08**Orchestrate** Software and configuration by signed plan. **03** On 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. **04** In the field ## Where this runs, sector by sector. 6 deployment scenarios from the sector research that rely on weather and environment.
