In a previous study by Niiler et al. (1992), advanced very high resolution radiometer (AVHRR) images were used for locating the Iceland-Faeroe front temperature distributions and gradients. In that study the satellite-sensed sea surface temperatures were found to contain an error after an atmospheric correction algorithm was applied. This was determined through a regression fit of AVHRR data against in situ aircraft-deployed expendable bathythermograph (AXBT) and conductivity-temperature-depth measurements. Recently, Minnett (1993) pointed out that an error occurred in that fit. As a result, we decided to repeat the comparisons of AVHRR sea surface temperature (SST) data against in situ measurements. After correcting several errors, we still find a shift of about 2 ¿C in the scatter of AVHRR against AXBT SST data. The bias (mean difference) was 1.73 ¿C, and the standard deviation was 0.3 ¿C. ¿ American Geophysical Union 1994
