Ecosystem Drought Response Timescales from Thermal Emission versus Shortwave Remote Sensing

Figure 6

TCI, VCI, and VHI positive-only and negative-only mean correlations globally with SPEI at different aggregation timescales. For the positive-only average, all negative correlations were set to zero, while, for the negative-only average, all positive correlations were set to zero. The dotted lines show the range over which the means would be not significantly different from zero.
