The animation shows month-wide build-up of BC pollution and its inter-regional transport over the Indian region. The BC pollution starts to rise from September onwards and is mainly over the northern IGP, followed by their rise also over the eastern IGP during October. The large burden of BC pollution is wide-spread over the entire IGP during November to February. It is also seen to build to a large value during December to February over the western India (including Maharashtra), and along the eastern coast (including areas of Andhra Pradesh) during November to February. The BC pollution remains large along the eastern IGP (around areas of Kolkata, Kharagpur, Bhubaneshwar) and eastern coast (e.g., including areas over Andhra Pradesh) during March, and is seen to specifically peak over the eastern coast during April. The animation also reveals the seasonality in the inter-regional or transboundary transport of BC pollutants. The seasonality in the transboundary transport has the role in wide-spread distribution of large BC burden. Transport of BC pollutants is visualised from eastern/lower Indo-Gangetic plain (areas of west Bengal region) towards eastern coast (e.g. areas of Odisha, Andhra-Pradesh region) during winter (November-December), Northeast monsoon, NEmon (January-February), Transition-to-summer, Tsumm (March); from western coast (areas of Maharashtra region) towards central India (e.g. Chhattisgarh, areas of northern Karnataka and Telangana) during NEmon and Tsumm. The transboundary transport is prevalent from the northern/upper IGP (e.g. Punjab/Haryana regions) towards near-by regions (e.g. Delhi/NCR) during Transition-to-winter, Twin (October). Additionally, movement from the northern IGP progresses towards the eastern and lower IGP, eventually reaching northeastern India during winter and NEmon.
