Weather Stations

 

Weather stations are used at each SEGA site to provide garden users with accurate data on a range of environmental conditions. SEGA weather stations include the instrumentation listed below. Some sensors are duplicated for redundancy or testing of multiple devices. The final sensor set may include other devices. Each garden site will also include several WiSARD wireless sensor devices supporting multiple soil moisture and temperature sensors Decagon 5TM volumetric water content sensors and Decagon MPS-6 water potential sensors).

Raw Near Real-Time Weather Conditions for all sites are available at: SEGA Weather

The most recent site image is avaliable at the individual garden page here: SEGA Gardens

Historic Image Collections and Derived Statisticas are avalible at the National Phenocam Network

Instrumentation
