Hi Graeme For the commercial sensors I don't always have many scenes available for testing. If you could share via email your specific input bundle for testing/development purposes I can take a look at it specifically. In this case there seem to be two potential issues in your settings file: 1) you ...

This post shows some examples of query and download of VIIRS data. VIIRS data are distributed as L1B and GEO files that can be directly processed by ACOLITE. The function will download both geometry and radiance data files for both I (375 m) and M (750 m) bands that can be used in ACOLITE processing...

Hi all Last week I pushed some changes to the GitHub that allow for processing of PACE/OCI data, with the availability of the first light data. This post will show some first results from OCI processing with ACOLITE. Note that this sensor and code are still in early operations and performance may va...

Hi Zhigang Do you mean negatives are retrieved in the NIR band? For the scene you sent (I got the collection 2 equivalent LC08_L1TP_042034_20200523_20200820_02_T1) I get some slight NIR negatives in part of the lake, marked in red. From the spectrum view you can see they are very close to 0. zhigang...
