Caption
Figure 1. Soon after the kharif/summer crops (mainly rice paddies) are harvested, large number of farm fires are detected from the satellites in late October to November over northwestern India (a:2022, b:2023; top row). A network of about 30 low-cost sensors has been deployed during the intense CRB period since 2022 (black circles in a, b). Our measurements show rural area air pollution in Punjab (c, d; middle row) and Haryana (e, f; bottom row) was significantly caused by paddy crop residue burning in the October-November months for both 2022 (left column) and 2023 (right column). The FDC maps, at 0.05×0.05 degrees grid resolution, are created from Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the SNPP and NOAA20 satellites hotspot detections. The background shows the visible image of earth’s surface.
