However, the extent and driving factors of the impact of warming on the absorption of CH<sub>4</sub>at 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 CH<sub>4</sub>. This dataset shows the daily CH<sub>4</sub>uptake 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 ℃).</p>",
