ACOLITE generic Rrs and Landsat 8 band names

[hnthang]

Hi Quinten,

Could you please clarify the name of Rrs band and the corresponding band name of Landsat 8? It seems a bit different in wavelength between the Rrs products and the original Landsat 8 band name.

Could I understand that:
Rrs_443 is Band 1
Rrs_483 is Band 2
Rrs_561 is Band 3
Rrs_655 is Band 4
Rrs_865 is Band 5
Rrs_1609 is Band 6
Rrs_2201 is Band 7
Rrs_592 is Band 8
Rrs_613 is Band ?

Thank you for your time to us.

Hi Thang

Your band order is correct! The 613 nm product is an orange band estimated from panchromatic, green, and red band reflectances by Castagna et al. 2020 (https://doi.org/10.3390/rs12040637). It was proposed to estimate phycocyanin/cyanobacteria from L8/OLI imagery.

Thank you very much. That's all I need.

Have a good day.
