Hi, it is not clear to me why to achieve high radiometric resolution, a greater instantaneous field of view (IFOV) is beneficial.

Thanks.

  Hi Jesús,
  thank for your question. A greater IFOV implies larger amounts of energy reaching the sensor, which allows for better radiometric resolution. Higher spatial resolution would require a smaller IFOV and therefore worse radiometric resolution. Hope this helps.

    Hi, is this some sort of limitation in the hardware or sensor design? i.e. sensors generally need to capture more energy over a larger instantaneous field of view to enable differentiation between different radiances?
