The significant warming and changes in soil freeze-thaw cycles during non growing seasons can significantly alter the net exchange rate of methane (CH4) between soil and atmosphere. However, the extent and driving factors of the impact of warming on the absorption of CH4at different stages of the F-T cycle in cold alpine ecosystems are still unclear, while alpine ecosystems have been found to be a net sink of atmospheric CH4. This dataset shows the daily CH4uptake of the alpine grassland ecosystem on the Qinghai Tibet Plateau after a 5-year warming experiment, including control, low-level warming treatment (5 cm soil depth+2.4 ℃), and high-level warming treatment (5 cm soil depth+4.5 ℃).
