Validation of MODIS aerosol optical depth over Yuandao in the North Yellow Sea

  • The latest version MODIS C061 aerosol retrievals were evaluated with collocated aerosol optical depth(AOD) from island-based Sun photometer over Yuandao in the North Yellow Sea.Based on the two kinds of data, the size of spatial-temporal windows were discussed and spatial window of 30 km×30 km and temporal window of ±0.5 h were selected.The validation results showed there was a good relationship between the MODIS AOD and the island-based AOD, the correlation coefficient was 0.98.The MODIS AOD products at 550 nm fell well within NASA expected error envelop (EE) ((0.04+0.1*AOD), (-0.02-0.1*AOD))in spring, autumn and winter, while the proportion within expected EE was only 40% in summer, the inconsistency between aerosol module assumption and in-situ may explain the lower precision of AOD in summer.
