SSH or SLA #15

Open AngelAmores opened 7 years ago

AngelAmores commented 7 years ago

Hello,

My concern is if the matlab codes you are providing are prepared for SLA data or for SSH data. In the paper it says that you used SLA data but in the codes it is written SSH everywhere. I am asking because I am getting pretty different results on the eddy polarity if I am using SLA or SSH. With SLA the most common eddy polarity in the Mediterranean, computed as (#ant - #cyc)/(#ant + #cyc), looks like a random map while with SSH it makes sense.

Thanks.

seleccion_030 This is what I was talking about. With the SLA dataset, the eddy polarity looks random while the same computations using ADT definetly it's not random. Why there is such a big difference? How is the eddy polarity defined? Just as the sign of the value of the field in the eddy center? I cannot figure out where the differences come from.
