摘要：

The study introduces regression-kriging technique to downscale land surface temperature (LST) over a heterogeneous landscape of India and compares it with other models. All models are initially tested on aggregated 960 m Landsat LST and downscaled to 240 m (RMSE = 0.45 degrees C) and 120 m (RMSE = 0.68 degrees C) resolution. Finally, the MODIS LST is downscaled to 250 m (RMSE = 0.7 degrees C) resolution. The proposed model outperformed compared to other models. The qualitative assessment reveals appearance of box-like structure is not seen in the proposed model-derived LST due to reconstruction of residual.
