Re: Missing Aerosol Optical Depth (AOD) Data in MYD04_L2
Dear LAADS_UserServices_Mm Many thanks for the quick response and explanation. In such missing case, would it be a good idea to fill up the missing values by making sub-grid and applying different imputation techniques? As an additional query, I am wondering if there is an example python code or cas...
