|NOAA Optimum Interpolation ¼ Degree Daily Sea Surface Temperature Analysis data (also known as Reynolds OI V2 SST data) were acquired from the NOAA´s NCDC webpage. AVHRR data were used due to its greater temporal coverage in relation to AVHRR/AMSRE data.
Daily files from 01-01-1982 to 12-31-2011, each bearing daily SSTs and associated standard deviations (SD), were imported into R as georrefered layers and stacked by chronological order. Data were retrieved separately for each coastal pixel (location) across the entire assemblage of temporal layers, worldwide. Coastal pixels were defined as those closer to land but with less than 50% of land contamination, which was assessed using full-resolution GSHHS coastline data. See the figure on the right.
