Ecosystem Drought Response Timescales from Thermal Emission versus Shortwave Remote Sensing

Figure 1

TCI, VCI, and VHI mean correlation globally with SPEI at different aggregation timescales. (a) Global mean, (b) evergreen broadleaf forest, (c) grassland, and (d) cropland. The dotted lines show the range over which mean correlations would be not significantly different from zero, as estimated from Monte Carlo simulations of sample correlation sizes.
