Effect of atmospheric radiance errors in radiometric sea surface temperature measurements
In situ radiometric measurements of the sea surface skin temperature (SSST) are typically obtained by using infrared radiometer systems mounted on ships. The emissivity of seawater is less than unity and the signal measured by a radiometer viewing the sea surface is mainly composed of sea surface radiance and a small (<2%) downwelling skying radiance component reflected at the sea-surface into the radiometer field of view. For a given sea view angle the effect of ship roll and pitch or non-simultaneous sea and sky radiance measurements may result in the determination of inappropriate sky radiance measurements.
