Note that HARP does not have any destripe correction built in. The destriping for CO is actually a destriping performed by the processor itself. The CO product contains both ‘normal’ and destriped column values.
Thank you Sander for your quick reply and thank you for pointing me to that other post. I’m already using the “ch4=bias_corrected” option but still observe stripes patterns. Sorry for my misunderstanding about thinking that HARP could do destripe correction. I wish it could.
