Chlorophyll benchmark file load error

[jabowery]

The Chlorophyll benchmark "output" file at https://www.seanoe.org/data/00807/91910/ results in the following error when I try to load it:

[1] import numpy as np
[2] oarr = np.load('ln_Chl_ref_norm_1998_2015.npy')
---------------------------------------------------------------------------

Hi,

Thank you very much for raising this issue. You are right that the file "Reference target satellite Chl over 1998-2015" seems indeed to be corrupted when downloaded from Seanoe. I will contact the platform to solve this problem.
However, you can in the meantime download the same reference target satellite data on this link : https://e1.pcloud.link/publink/show?code=XZ9rfmZMAsMwhIJbw8MKJa7kUBAVFuikjfk
or the corresponding transformed and normalized data here : https://e.pcloud.link/publink/show?code=kZ5TyuZeuTIPNKWtsS02f60baCweJlIfwVy ("ln_Chl_ref_norm_1998_2015.npy").

Hope this solves your problem,
Regards,
Joana
