A Stepwise Calibration of Global DMSP/OLS Stable Nighttime Light Data (1992–2013) [PDF]

Remote Sensing, 2017
The Defense Meteorological Satellite Program (DMSP)/Operational Linescan System (OLS) stable nighttime light (NTL) data provide a wide range of potentials for studying global and regional dynamics, such as urban sprawl and electricity consumption. However, due to the lack of on-board calibration, it requires inter-annual calibration for these practical

Landscape Fragmentation Driven by Land Use Change Dominates the Spatiotemporal Heterogeneity of Non‐Point Source Pollution Loads in Human‐Intensive Basins: A Case Study of the Dongjiang River Basin, China

Land Degradation &Development, EarlyView.
ABSTRACT Landscape fragmentation may influence the spatial distribution and temporal variation of non‐point source (NPS) pollution by altering hydrological processes, pollutant transport pathways, and ecosystem service functions. However, under the combined effects of natural factors (e.g., precipitation, topography) and anthropogenic factors (e.g ...
