Hello every body,,,,,
Is there a list of band combinations for Sentinel 3 available?
something similar to the band combinations of Landsat 8 and 7 for:
Natural Color
False Color (urban)
Color Infrared (vegetation)
Agriculture
Atmospheric Penetration
Land/Water
Natural With Atmospheric Removal
Vegetation Analysis ..........etc
Dear Faisal,
You seem to mix "band combination" and "products". The OLCI instrument onboard Sentinel 3 is very close from the MERIS instrument onboard Envisat. You can make any band combination from such product with standard remote sensing software to render a "natural" aspect RGB image, or compute a NDVI (I guess it's what you call "color infrared vegetation"?).
"Atmospheric removal" is more about the processing level you want. You may have a look at the specification document here :

May be the same with band combinations for sentinel 2
Landsat 8 band combinations : Natural Color 4 3 2 False Color (urban) 7 6 4 Color Infrared (vegetation) 5 4 3 Agriculture 6 5 2 Atmospheric Penetration 7 6 5 Healthy Vegetation 5 6 2 Land/Water 5 6 4 Natural With Atmospheric Removal 7 5 3 Shortwave Infrared 7 5 4 Vegetation Analysis 6 5 4
You can try it, good luck
Just add some details in Jerome Colin's answer. First you imagine a mapping from wavelengths to color. For example, at 470 nm (+/- 20) is considered Blue, at 540 nm (+/- 20) Green, 680 nm (+/- 20) Red, from outside 780 nm upto 1 milimeter is InfraRed (divided furthermore into Near InfraRed - NIR, Middle, Thermal, Far IF etc.). Note that I am using the normal perception of color, i.e the RGB scheme. Then lookiing at the spectral specs of Sentinel-3, we can approximately classify bands Oa-3 and Oa-4 as Blue, bands 5 and 6 as Green, 7 to 11 as Red, 12 to 16 as "between Red and NIR", and bands 17 to 21 as NIR. Now you apply the "Band ratio" in RS as for ex NDVI=(NIR-Red)/(NIR+Red), Land-water index=NIR/Green etc. Hope this can help you more. Good luck!
On this site you have comparation of Sentinel 2 vs Landsat 8; 7

Bends ranes are similar but different number (name).
