Amount and timing of permafrost carbon release in response to climate warming
The thaw and release of carbon currently frozen in permafrost will increase atmospheric CO 2 concentrations and amplify surface warming to initiate a positive permafrost carbon feedback (PCF) onExpand

Recent permafrost warming on the Qinghai‐Tibetan Plateau
[1] Permafrost temperature monitoring through 10 boreholes up to 10.7 m depth has been conducted half-monthly from 1996 through 2006 along the Qinghai-Tibetan Highway. The primary results show thatExpand

Snow depth derived from passive microwave remote-sensing data in China
Abstract In this study, we report on the spatial and temporal distribution of seasonal snow depth derived from passive microwave satellite remote-sensing data (e.g. SMMR from 1978 to 1987 and SMM/ IExpand
