Rapid estimation of coniferous forest leaf area index using a portable integrating radiometer

Canopy transmittance was measured at 1200 and 1400 local solar time using an integrating radiometer on seven coniferous forest stands in western Montana, ranging in projected leaf area index (LAI) from 1.7-5.3 m^2/m^2. Transmittance of each 1-ha stand was measured at 96,000 points, yet measurement r...

Zusammenfassung:	Canopy transmittance was measured at 1200 and 1400 local solar time using an integrating radiometer on seven coniferous forest stands in western Montana, ranging in projected leaf area index (LAI) from 1.7-5.3 m^2/m^2. Transmittance of each 1-ha stand was measured at 96,000 points, yet measurement required
