Abstract Global spatial distribution of vegetation is determined jointly by climate, monsoon, ocean current and human activities. In recent decades, surface changes caused global warming, extreme climate events intensified activities need a further understood. this paper, we adopted available MODIS land cover dataset (MCD12Q1) to investigate the feature sand dynamics during past 20 years. Resul...

Moderate resolution imaging spectroradiometer (MODIS) time series (TS) have been widely applied for flood monitoring in large tropical wetlands. However, little systematic work is available on the influence of pixel quality, vegetation cover, and annual hydroclimatic cycle classification performance. In this study, issue examined based a six-year, 250 m MOD13Q1 TS underpinned by extensive situ ...

After long periods of deforestation, forest transition has occurred globally, but the causes of forest transition in different countries are highly variable. Conservation policies may play important roles in facilitating forest transition around the world, including China. To restore forests and protect the remaining natural forests, the Chinese government initiated two nationwide conservation ...

Abstract. Land cover (LC) determines the energy exchange, water and carbon cycle between Earth's spheres. Accurate LC information is a fundamental parameter for environment climate studies. Considering that in China has been altered dramatically with economic development past few decades, sequential fine-scale monitoring urgent need. However, currently, fine-resolution annual dataset produced b...

introduction thermal infrared integrated dust index (tiidi) is one of indices that is presented in this direction. the index operates based on four brightness temperature difference including wavelengths 3.7, 8.6, 11 and 12 micrometer. according to the studies, btd (bt12-bt11) is used for cloud detection. btd (bt8.6-bt11) is the index for separation for dust from sandy surface and btd (bt3.7-bt...
