      For Spain that is close to
      the same resolution as HRPT (1km at sub satellite point).

      In theory maybe, but HRPT always looks much better than HRV as does HRPT
      against GVAR. Maybe it's the optics ?

        Or maybe it's because the NOAAs look straight down instead of at an
        angle similar to the sun, and consequently see more cloud and terrain
        shadows, giving the impression of greater contrast and clarity.
