The global measurement of sea surface temperature (SST) has for many years operationally relied on infrared (IR) radiometer systems flown on polar orbiting and geostationary platforms. Although offering spatial resolution (approximately 1 km), high radiometric fidelity, and daily global coverage, the presence of the earthÆs surface is enveloped by clouds with certain oceanic regions having persistent cloud cover lasting for weeks. Detection of cloud contaminated observations is generally more successful during daytime when visible and near-IR image data can be used in synergy. Nevertheless, the contaminating effect of this cirrus or sea fog is particularly difficult to detect and the formidable problem of sub-pixel size clouds and their effect on IR-SST is depressingly unresolved.
