Preliminary Evaluation of GOES-16 ABI Aerosol Optical Depth Product
Abstract
The Advanced Baseline Imager (ABI) on the GOES-16 satellite measures radiances in multiple wavelengths from the UV through the IR at high spatial and temporal resolution. Thus aerosol optical depth (AOD) products derived from ABI can potentially have statistical qualities similar to those from the MODIS and VIIRS onboard polar-orbiting satellites. In this presentation, we show validation results obtained from the ABI observations co-located with near real-time Level 1.5 AERONET ground measurements from 04/29/2017 to the present. The GOES-16 AOD product used in this study was generated offline. An operational product with similar qualities is expected to become available in the near future. The validation results show that the GOES-16 AOD overall bias is about 0.02/0.01 and the standard deviation is about 0.10/0.04 over land/water, respectively. Those biases and standard deviations are comparable with those from VIIRS and MODIS at AERONET sites. The high temporal resolution of GOES-16 allows us to study the AOD as a function of the time of day. The bias is relatively larger in the morning than in the afternoon over land; and it has little diurnal dependence over water.
