| Abstract | The effects of aerosol on radiation which plants use for photosynthesis or Photosynthetically Active Radiation (PAR) have been investigated. PAR, part of short-wave radiation (SR) with 400-700 nm in wavelengths is measured by a photosynthetically active radiometer (model MFR-7). The quantity of aerosols in atmosphere is measured as Aerosol Optical Depth (AOD). In addition, data of Light Intensity (LI) are collected for analysis with PAR and AOD. The instrument used in aerosol measurement is a sky-radiometer (POM-I). The solar radiation is measured by pyranometer. PAR, AOD and pyranometer data (May 2003 April 2004) at Observatory for Atmospheric Radiation Research, Amphoe Sri Samrong ,Sukhothai Province have been collected. PAR parameters are total, diffuse and direct which were observed during sunrise. Data were then analyzed by a spread sheet program. |
