渤海海域 CALIOP 与 MODIS 气溶胶光学厚度相关性分析
Correlational research on aerosol optical depths from CALIPSO and MODIS/Aqua over the Bohai Sea
摘要
Abstract
Taking the Bohai Sea as a subject, this research conducted correlation fitting analysis of aerosol optical depth at 532 nm derived from CALIOP aerosol profiles and at 550 nm derived from MODIS/Aqua aerosol profiles at different spatial sampling scales (10 km × 10 km, 30 km × 30 km, 50 km × 50 km, 70 km × 70 km and 90 km × 90 km) and time scales (day, month and season). It was found that smaller spatial scale and larger time scale could illustrate the characteristics of aerosol better than others do. With a correlation coefficient over 0.950, the results demonstrated a good correlation between quarterly averages from the two sensors under the 10 km × 10 km window in spring and autumn. The research showed that in specific temporal and spatial unit these two kinds of data manifest good correlation, which may provide a new method for research on aerosol optical depth over the Bohai Sea.关键词
