[THREDDS #LUC-457370]: Question on latitude for gridded data set

The longitude is in degrees east of the Greenwich meridian. So 1 is just east 
of the meridian and 359 is just west. The prefered input for 75 W would be 285. 
I'm not sure about what -75 returns. I'm guessing that gets converted to 285 
internally as well but I'm not absolutely sure.
