Development of a semi-parametric PAR (Photosynthetically Active Radiation) partitioning model for the United States, version 1.0
Photosynthetically Active Radiation United States
2014/12/19
A semi-parametric PAR diffuse radiation model
was developed using commonly measured climatic variables
from 108 site-years of data from 17 AmeriFlux sites. The
model has a logistic form and improve...
Varietal Difference in Morphology and Photosynthetically Active Radiation Distribution in Spring Wheat Canopy
Canopy structure Crop ideotype PAR penetration Sowing time Spring wheat variety
2009/8/4
It has been generally believed that the crop ideotype canopy has an erect small leaves to allow the photosynthetically active radiation (PAR) to penetrate deeply. In wheat, this might be not always ap...
Seasonal Changes in Distribution of Intercepted Photosynthetically Active Radiation for Layer and Dry Matter Production in Spring Wheat Canopy
Efficiency of dry matter accumulation Crop growth rate Photosynthetically active radiation Slope of flag leaf Spring wheat

In order to understand the relationship between solar radiation and biomass production within crop canopies, penetration, reflection, and interception of photosynthetically active radiation (PAR) were...
Effect of smoke and clouds on the transmissivity of photosynthetically active radiation inside the canopy
Effect of smoke and clouds transmissivity of photosynthetically active radiation canopy
2009/1/7
Biomass burning activities emit high concentrations of aerosol particles to the atmosphere. Such particles can interact with solar radiation, decreasing the amount of light reaching the surface and in...
