Fig. 2 Trends of mean-layer temperature anomalies during 2019-2024 for the 9 channels analyzed in this study, averaged over the globe, ocean, and land for NOAA (a), FY-3D (b), and their differences (c). (The bars represent trends with error bars superimposed on them. The trend uncertainty represents 95% confidence intervals with autocorrelation adjustments, which account for time length limitations and temporal variability. The black dashed lines in (c) represent the stability thresholds for the 9 channels)
