On large (global and hemispheric) scales, sea surface temperature (SST) anomalies are considered to be good surrogates for marine air temperature (MAT) anomalies. Here we investigate how MAT and SST anomalies from instrumental measurements compare regarding a few crucial aspects of their variability including seasonality and multiannual trends. We make use of MAT and SST data acquired by moored buoys constituting the Tropical Atmosphere Ocean (TAO) array. Buoys are managed by the Pacific Marine Environmental Laboratory (PMEL), which is part of the National Oceanic and Atmospheric Administration (NOAA) agency of the United States of America. We  aim at answering the following questions: How do the monthly average anomalies of SST and MAT compare? Do observed MAT and SST data contain significantly different multiannual trends?
