Dense measurement network revealed high level of PM2.5 in Punjab due to crop residue burning and its transport to Haryana and Delhi NCR

Very high particulate pollution over northwest India captured by a high-density in situ sensor network

A group of international collaborators led by the Research Institute for Humanity and Nature (RIHN) team performed the first quantitative study of air pollution in the north-western India region using 29 low-cost and reliable instruments, demonstrating the advantages of source region observations to link crop residue burning (CRB) and air pollution at local to regional scales.
