Re: Clarification on CAD Score Screening and Use of Extinction Coefficient Uncertainty in CALIPSO V4.51 Aerosol Product
Thank you for the clarification.
Understood — So, there's no rigid threshold for the CAD score for scientific use, the higher the CAD magnitude, the better the confidence.
Appreciate the guidance!

Cloud Effective Radius in MYD06_L2
Hello, I am working with MODIS Aqua Level 2 cloud products (MYD06_L2) where I need cloud effective radius (CER) observed at 2.1 micrometer. I found the CER at 1.6 um ( e.g., Cloud_Effective_Radius_16) and CER at 3.7 um ( e.g., Cloud_Effective_Radius_37) but not at 2.1 micrometer in the file specific...

Re: Issue while uploading zipped shapefile.
Yes, the shapefile contains a lot of coordinates as vertices, but it is tanking too much time even more than 6hrs, that I tried recently.
Thank you for the suggestion I will try this with a reduced-size shapefile.
