A weather station is a facility or a collection of instruments used to observe and record atmospheric conditions at a specific location. These stations can be found in various forms, from simple home setups to sophisticated installations operated by meteorological agencies. Key components typically found in a weather station include: 1. **Thermometers** - Measure air temperature. 2. **Barometers** - Measure atmospheric pressure. 3. **Hygrometers** - Measure humidity levels.

A weather station is a set of instruments measuring atmospheric conditions at a specified site. A thermometer records temperature, a barometer records pressure, an anemometer records wind, and a rain gauge measures collected rainfall. Moisture observations may be reported as relative humidity or dew point.
Instrument exposure is part of the measurement. Direct sunlight can heat a temperature sensor above the surrounding air; nearby buildings alter wind; the height and averaging interval affect comparability. A long record therefore needs instrument and site metadata as well as numbers. Consistent observations support both immediate meteorology and the statistics used in climatology.
