Question about dataset with bands 2,8,9 - Red blur in some areas

Optical Toolbox
1

Hello,

I tried downloading a dataset, similar to the RGB (Sentinel-2A), but this time using bands 2, 8, and 9. I noticed that there is a red blur in some areas of my images. Is this normal? Could it be related to atmospheric correction, or is it an issue with the data?

I have attached a screenshot to show the effect. The last image is a true color which is fine.

Thanks in advance!

The reason probably is that band 9 has only a resolution of 60 meter and is probably interpolated to the 10m of band 2 and 8.

Dear Marco,
thank you for your instant reply, i thought the same but i have already resampled the bands to 10m resolution.
thank you,
Alexandra

Yes, this resampling introduces the blur. You don’t get the same accurate values and sharpness.
