Fig. 1: Potential effects of different sizes of regions of interest (ROIs) with varied footprints of rice paddies.

The red and blue ROIs are from our study1 and Zeng et al.2, respectively. The paddy rice maps were retrieved from MODIS data with the 500-m spatial resolution (a) and 0.5° spatial resolution (b) in monsoon Asia in 2010, respectively. Detailed spatial distributions of rice paddies in local regions labeled with blue rectangles and spatial resolutions of 500 m (c–f), 0.5° (g–j), and 2° × 2.5° (k–n). The red and blue numbers show the mean of rice paddy area proportion in ROIs with red and blue color, respectively.
