Goddard Institute for Space Studies (GISS). Line plot of monthly mean global surface temperature anomaly. The black line shows meteorological stations only; redle dots are the land-ocean temperature index, as described in Hansen et al. (1999). The land-ocean temperature index uses sea surface temperatures obtained from satellite measurements of Reynolds and Smith (1994).
