An Improved Method for Measuring AOD Using Field Spectrometer

Abstract:

Aerosol optical depth (AOD) was an important parameter of the aerosol monitoring. This study had proposed an improved method for measuring AOD using field spectrometer, which included a basic algorithm and a correction model together. By using this method, the AOD observed by field spectrometer kept quite consistent with those observed by sun photometer. The RMS of AOD observed by field spectrometer was less than 0.05 which met the precision requirement of the WMO. Besides, this method did not need long time to operate the instrument, and had no strict requirement for platform stability. So the improved method could be used to measure marine aerosols more accurately and handily, and it belonged to contribution for marine remote sensing technology.
