Figure 10. Cumulative agricultural fire detections over China from May to November 2008, where each red dot represents a single agricultural fire site identified from 1.1 km AVHRR and FY active fire pixels. Correlation coefficient images at 1° × 1° horizontal resolution between daily mean BC larger than the average (2.52 mgm−3) measured at Tongyu and corresponding 1 day cumulative agricultural fire‐site counts in different intervals during the sampling period.
