Thermal remote sensing for mapping the sub-Arctic permafrost and refining its southern limits.
Int. J. Appl. Earth Obs. Geoinformation(2023)
摘要
•A MODIS look-up-table converts daily thermal imagery to ground surface temperature.•An MAGT-based probability index is built to estimate permafrost continuity.•The southern limits of sub-Arctic permafrost are extracted at a km-scale.•Carbon release in the southern limits of permafrost deserve further investigation.
