Urban impervious surface (UIS) is a key parameter in climate change, environmental and sustainability. UIS extraction has been evolving rapidly the past decades. However, high-resolution mapping long-term need. There an urgent requirement for from remote sensing imagery. In this paper, we compare current methods terms of units models summarize their strengths limitations. We discuss challenges ...

Abstract Soil degradation is one of the main environmental issues within international agendas on sustainability and climate adaptation. Among processes, soil sealing represents major threat, as ecosystem services dramatically decrease or are even nullified. The increasing use big open data from satellites combined with AI algorithms making geodata mining mapping techniques essential to quantif...

Although spectral mixture analysis has been widely used for mapping the abundances of physical components of urban surface with moderate spatial resolution satellite imagery recently, the spectral heterogeneity of urban land surface has still posed a great challenge to accurately estimate fractions of surface materials within a pixel. How to dealing with the highly spectral heterogeneous nature...

Rapid urbanization with intense land use and land cover (LULC) change and explosive population growth has a great impact on water quality. The relationship between LULC characteristics and water quality provides important information for non-point sources (NPS) pollution management. In this study, we first quantified the spatial-temporal patterns of five water quality variables in four watershe...

An ocean-climate model that shows high fluxes of anthropogenic carbon dioxide into the Southern Ocean, but very low storage of anthropogenic carbon there, agrees with observation-based estimates of ocean storage of anthropogenic carbon dioxide. This low simulated storage indicates a subordinate role for deep convection in the present-day Southern Ocean. The primary mechanism transporting anthro...

The urban stream syndrome may not be limited to streams in urbanized watersheds. We measured the spatial pattern of impervious cover in ∼82,800 small watersheds across the conterminous United States by comparing watershed-based and stream-based measures of imperviousness. The watershed-based measure was the commonly used watershed percentage impervious cover. The stream-based measure was the pe...
