Overview

Uses

Leaf Area Index
In some types of canopy you can estimate leaf area index (LAI) with
reasonable accuracy. For best results a BF5 sensor should also be used.
PAR measurements
SunScan can be used as a portable line quantum sensor for measuring
levels of photo-synthetically active radiation (PAR) in plant canopies.
Fractional Interception
You can also measure what fraction of the solar radiation is being
intercepted by a plant canopy. For best results include a BF5 Sensor.
PAR Mapping
You can rapidly find average levels of PAR beneath the canopy, or make
linear transects of the PAR distribution within a canopy.
Auto-logging and Linear Quantum Sensor modes
You can leave SunScan unattended, automatically logging variations in
PAR at one place.
Data may be logged either to a PDA, or to an analogue data logger.
PDA logging is best, the Autolog utility giving the most measurement
options.
If used with an analogue data logger, SunScan functions as a line
quantum sensor with a single analogue output. See Appendix A.
