Data for the manuscript “Warmer and wider river systems accelerate permafrost thaw on the Third Pole”

This dataset provide key data of the study “Warmer and wider river systems accelerate permafrost thaw on the Third Pole”. This study investigates the dynamics of a representative permafrost river on the Third Pole and the corresponding changes of underlying permafrost. The results indicate a widening and warming trend of the river, which accelerates the sub-river permafrost thaw.
