Re: Improve ACOLITE by changing ancillary data locally?
Hi colleges, Regard my research, a water column correction is necessary after the step of atmospheric correction. Therefore, a K_d for Landsat 5/7 data is very important to reduce the impact of water column on image pixel values. For this reason, I attempted to find a reliable solution for the estim...

Re: Improve ACOLITE by changing ancillary data locally?
Another paper on the estimation of K_d from Landsat 5/7:
Remote sensing of diffuse attenuation coefficient patterns from Landsat 8 OLI imagery of turbid inland waters: A case study of Dongting Lake
Is it confidence enough to use the empirical model from the paper for the estimation of K_d?

Re: Improve ACOLITE by changing ancillary data locally?
Can we estimate the k_d at 490nm? This paper presented the estimation of k_d from landsat and ALOS AVINIR-2: Estimating the diffuse attenuation coefficient from moderatespatial resolution, multi-spectral satellite data in a seagrass environment - https://ieeexplore.ieee.org/document/6721154 but I do...

Kd from Landsat 5 and 7
Thank you for your explanation. It's clear to me now.
May I ask you about k_d? Currently, ACOLITE produce k_d only from L8 and S2. Will it be available for Landsat 5 and Landsat 7 in the next release?
Many thanks!

Improve ACOLITE by changing ancillary data locally?
Hello, I run ACOLITE for a scene of Landsat 8 and Sentinel 2 for seagrass mapping in the lagoon. For this purpose, I just need the Rrs of water pixel. Could you please to clarify some issues for me as follows: 1. How can we check the retrieval of ancillary data? From the log file? 2. The using of de...
