## Editorial
The KMSS (High-resolution VIS/IR Radiometer) is a passive optical instrument designed for land and cloud imaging. It flies on Meteor-M satellites.

KMSS comprises three camera heads: one MSU-50 unit and two MSU-100 units.[^wmo-oscar-kmss][^eoportal-meteor-m1] The MSU-50 unit operates at 120 m ground sampling distance and covers three bands in the ultraviolet-to-green spectral region (370-450 nm, 450-510 nm, and 580-690 nm).[^wmo-oscar-kmss][^eoportal-meteor-m1] The two MSU-100 units together cover three bands in the red and near-infrared region (535-575 nm, 630-680 nm, and 760-900 nm) at 60 m ground sampling distance.[^wmo-oscar-kmss][^eoportal-meteor-m1] The three camera heads together provide six spectral bands spanning from the ultraviolet to the near-infrared.

KMSS supports vegetation index mapping, optical time-series change detection, and burned-area mapping.[^wmo-oscar-kmss]
