China has a serious wildfire problem with a large number of fires in the south of the country especially during the winter (DJF) and spring (MAM) seasons. This study focused on identifying the causes of variability in inter-annual fire seasons. The relationship between fires and climatic parameters (precipitation, evapotranspiration and potential evapotranspiration) was evaluated on annual and seasonal...
Central Asia and Xinjiang, China are conjunct areas, located in the hinterland of the Eurasian continent, where the snowfall is an important supplement water resource. The induced seasonal snow cover is vita factors to the regional energy and water balance, remote sensing plays a key role in the snow mapping filed, while the daily remote sensing products are normally contaminated by the occurrence...
Lake ice is an important component of the hydrosphere and cryosphere, especially over high-lat itudes regions of High Mountain Asia (HMA), the long-term changes of freezing and thawing time can directly reflect the changes of climate. Remote sensing technology provides unreplaceable complement for HMA where the lake ice phenology is almost no monitoring, except that of Qinghai Lake. Considering the...
Vegetation phenology tracks plants' lifecycle events, revealing the response of vegetation to global climate changes. Microwave backscatter is insensitive to signal degradation from solar illumination and atmospheric effects and could provide an alternative data source to optical remote sensing in phenology studies. In this study, we analyzed a time series of Ku-band radar backscatter measurements...
The Qinghai-Tibet Plateau is one of the most sensitive and fragile regions to climate changes, which has been found experiencing distinct warming trend in recent decades. We detected the vegetation greenness trends with the MODIS data in the Qinghai-Tibet Plateau during 2000–2009. The annual average normalized difference vegetation index (NDVI) increased 0.036 yr−1 in this region. Statistically significant...
