Toward Estimating Climatic Trends in SST. Part I: Methods of Measurement

摘要: Abstract To assess climatic changes in sea surface temperature (SST), the measurement method with time and effect of these on mean SST must be quantified. Observations from International Comprehensive Ocean–Atmosphere Data Set (ICOADS) have been analyzed for period 1970 to 1997 using both metadata contained within dataset a World Meteorological Organization (WMO) catalog observing ships. The WMO were particularly important identifying engine-intake SSTs during 1970s, but increased identification over entire period. There are strong regional variations preferred method, most common Pacific bucket by countries bordering Atlantic. number increases becomes more numerous than buckets early 1980s. significant differences between observations made different methods. rounding r...
