From: On the interchangeability of sea-surface and near-surface air temperature anomalies in climatologies
Comparison between spatial-average deseasoned SST and marine air temperature (MAT) estimates over the equatorial Pacific region for the period 1980-2010 from different datasets, with associated linear trends. Thick continuous line: mean; dashed lines: 5-95 percentile range of available individual observations at each time step. All data are interpolated to the TAO grid data (see methods). The shading in panels a and b reports the temporal evolution of data availability for TAO data and Hadley data, defined as follows: for the TAO data (grey), the data fraction refers to the number of buoys generating 10-minute, hourly and daily data over the total number of buoys comprising the TAO array. For Hadley data (pink: HadNMAT; pale blue: HadCRUT), the data fraction refers to the number of grid points with actual measures over the total number of grids in the considered spatial domain (see methods). Trends are calculated at the 95% confidence level.
