Spatiotemporal variations of atmospheric black carbon concentrations in Kolkata and Howrah Municipal corporation areas
He West Bengal Pollution Control Board (WBPCB) invited The Energy and Resources Institute (TERI), New Delhi, to submit a proposal to analyze the spatiotemporal variations in atmospheric BC in Kolkata and Howrah cities. Accordingly, TERI submitted a technical and financial proposalto WBPCB to prepare an annual spatiotemporal variation of atmospheric BC concentration over Kolkata and Howrah in March 2023. Following the review of the proposal by experts, WBPCB awarded the project to TERI on 10th May 2023 (Memo No. 1139/1K-1/2021). Under the memorandum of understanding (MoU) signed (e-stamp Certificate No. lN-Dt_93620208110842U) between the WBPCB and TERI in May 2023. The objectives of the projects are,
1. Spatiotemporal variation of atmospheric BC concentration in KMC and HMC areas during the winter period.
2. Spatiotemporal variation of atmospheric BC concentration in KMC and HMC areas during the summer period.
3. Sectorial emission inventory of BC in KMC and HMC areas.
This report is divided into three chapters: I. Measurement of atmospheric BC in Kolkata and Howrah, II. Sectoral emission inventory of atmospheric BC in Kolkata and Howrah, and III. Spatial variation of atmospheric BC concentrations in Kolkata and Howrah. The sectoral activity data estimated from the survey conducted during the air pollution source apportionment and atmospheric carrying capacity study in Kolkata and Howrah was used to built the sectorial emission inventory of BC.
