Monitoring coastal water quality is important and the sea surface temperature is one of the key parameters of water quality. It plays a significant role in studying climate change and oceanic environmental processes. SST has always been measured with buoys and thermometers in the field and by remote sensing. The use of remotely sensed SST is significantly more common for mapping SST with a wider area and at high temporal resolution. Remotely sensed SST, however, may reveal uncertainties due to factors such as water depth and turbidity. This is in addition to the atmospheric effects, such as dust, fog, wind, solar angles, and humidity. Thus, remote sensing SST estimation is compared to the measured in-situ SST for the Arabian Gulf waters, and the critical atmospheric and oceanic variables contributing to the errors are identified
