SunScan Canopy Analysis

Solar Radiation

The SunScan Canopy Analysis System uses field measurements of Photosynthetically Active Radiation (PAR) in crop canopies to provide valuable information about Leaf Area Index (LAI) and biomass production.


  • Measures incident and transmitted PAR in canopies SunScan Canopy Analysis System - direct and diffuse solar radiation schematic
  • Direct display of Leaf Area Index (LAI)
  • Optional above canopy sensor for immediate calculation of direct/diffuse levels
  • Usable in cloudy, clear or changeable conditions



  • SunScan Probe - 64 PAR sensors embedded in a 1m long probe. Average readings and/or individual readings from all sensors can be recorded.
  • PDA - all readings received to a PDA running Win Mobile software. A ruggedised PDA is offered, or software is available for your own PDA
  • Optional BF3 PAR sensor - mounted above the canopy, this sensor calculates the proportions of diffuse to direct sunlight, enabling immediate calculation of LAI under a range of weather conditions
  • Optional wireless connection - allows the BF3 sensor to be mounted completely independently of the SunScan probe for maximum flexibility
