I would like to know, when I export data in earth coordinates with WinADCP, I get variables u(East) and v(East), what is the coordinates of u and v for an ADCP upward looking, is it (S;F;M) in the doc RDI or (X,Y,Z) with Z toward the floor?
I have checked the web, but couldn't find any information about the coordinates. I recommend downloading the User Guide which is available on the FTp of the developer.

You also have the possibility of downloading the software as well.
