英文摘要: Anewsea surface temperature (SST) climatologicalmean was constructed using the first 30 years (1982-2011) of the NOAAdaily optimuminterpolation (OI) SST. The daily analysis blends in situ and satellite data on a 1/ 4° (~25km) spatial grid. Use of an analysis allows computation of a climatological value for all ocean grid points, even those without observations. Comparisons were made with a monthly, 1°-spatial-resolution climatology produced by the National Centers for Environmental Prediction, computed primarily from the NOAA weekly OISST. Both climatologies were found to provide a good representation of major oceanic features and the annual temperature cycle. However, the daily climatology showed tighter gradients along western boundary currents and better resolution along coastlines. The two climatologies differed by over 0.6°C in high- SST-gradient regions because of resolution differences. The two climatologies also differed at very high latitudes, where the sea ice processing differed between the OISST products. In persistently cloudy areas, the new climatology was generally cooler by approximately 0.4°C, probably reflecting differences between the input satellite SSTs to the two analyses. Since the new climatology representsmean conditions at scales thatmatch the daily analysis, it would be more appropriate for computing the corresponding daily anomalies. © 2014 American Meteorological Society.
