Dear Quinten I did the changes and I looked and the output, the problem was related to the lack of pyhdf python module on my system. So acolite could not read the hdf ancillary files. I have installed the pyhdf module and reverted the changes that you suggested to identify the problem, and now the m...

Hello Quinten I have added ## EarthData EARTHDATA_u= EARTHDATA_p= to config/acolite_config.txt file Although that is not the problem, the ancillary data download was already OK in my system. The problem is why acolite log is showing/doing this?: 2020-03-11 16:38:31: Processing 1 scene... 2020-03-11 ...

Hello

I will look for images where aerosol changes inside outside from islands wakes could be identified. Although the illumination patterns will not be the same, I will use to MODIS and VIIRS data to check and compare.

Hello Quinten Thank you very much for your prompt, complete and useful answer. The changes that you has pointed out, has improved a lot the results. You were right about the fact that glint over wake was the major issue. Although islands downward wakes also produces different patterns of aerosol acc...

Hello Thank you very much for providing acolite software and their support. We are processing Landsat 8 and Sentinel 2 data using acolite 20180908.0 version.When the quality of the input data were good the results were great. However, our area of interest is highly complicated from atmospheric aeros...

Dear Quinten

I have made the modifications that you suggested. The processing is working now, both landsat 8 and sentinel 2. I have done few tests, but they have been working,

Thank you very much!!!

I have tested it in two different computers, both running linux ubuntu 18.04. However neither gui nor command line generated the L2W file after the generation of L2R fi...
