PREDECIMEL

Prede Cimel Comparison

3 June 2007 - 29 June 2007

Lead Scientist: Connor Flynn

Observatory: SGP (Southern Great Plains)

A commercial Prede tracking Sun Photometer was deployed at the Southern Great Plains site for direct comparison to the ARM CSPHOT Cimel Sun Photometer. The Cimel Sun Photometer forms the basis of the NASA Aeronet network of sun photometers while the Prede is used widely in Asia. The Aeronet and Asian aerosol networks are playing increasingly important roles in characterizing global aerosol distributions. Aerosols play a complex role in climate on local and extended scales, impacting air quality, affecting the degree and nature of cloud cover, and the frequency and abundance of precipitation and water resources. A side-by-side comparison of these two instruments had never been conducted.
