We estimated sub-pixel urban cover at 250 m resolution in China for 2001 and 2010.

We fused 250 m, 500 m, and 1 km MODIS data and DMSP/OLS nighttime lights data.

Separate regression models estimated for temperate and subtropical regions of China

City-level assessment showed good agreement with Landsat-based urban information.

Regional mapping demonstrated utility of this method for large-area application.
