Intrinsic differences in
reflectivity between the metal segments allow individual particles to be identified by conventional optical microscopy.
Using the Shallow Radar instrument aboard NASA's Mars Reconnaissance Orbiter, Holt was able to peek beneath the ice's surface for clues; in particular, the radar could pick out differences in electrical
reflectivity between overlying layers, showing how the ice built up over time.

between a surface's
reflectivity and its age.

reflectivity, which causes the mirror effect that makes tablets terrible for use in bright sunlight.

between the seasonal variability derived relationship of low cloud
reflectivity with SST and ECS is dominated by «bad» models that are inconsistent with the observational constraint.
