Cardiff Temperature & Pressure

The graphs below normally span four days and have the most recent readings on the right hand side.

• The temperature is monitored using a DS18B20 temperature sensor which is inside a small Stevenson Screen about one metre above ground.
• Temperature readings for the rolling four-day graph are normally taken every hour, on the hour.
• The pressure sensor is a MPL3115A2, at ground level.
• Pressure readings for the rolling four-day graph are taken every hour on the hour.
• From time to time, additional temperature and pressure readings may be taken on the half hour; these are not plotted.
• The location is about 46M (150 ft) above mean sea level.
• This facility is experimental and may be withdrawn at any time without notice.
