Investigations of black carbon aerosol sources and strengths over a rural-valley location in Haryana, India

Observations of equivalent Black Carbon (eBC) aerosols were carried out at Panchgaon, a rural site in Haryana, nestled amidst the Aravali hillocks (285 m AMSL) in northwest India. These measurements were carried out using a next-generation seven-wavelength Aethalometer (AE33) fro...

Assessing the skill of a biogeochemical model tailored to a global coupled forecasting system: a case study for the Bay of Bengal carbon cycle

To achieve real-time prediction of surface ocean carbonaceous variables in the Indian Ocean, we integrate an extended-range coupled forecast system with a global ocean biogeochemistry model incorporating an explicit carbon cycle. The physical ocean state is provided by the Indian...

Unveiling hidden air pollution exposure and impacts with low-cost sensor network-based frameworks

India has made some progress in mitigating severe air pollution; however, many regions continue to experience fine particulate matter (PM2.5) levels exceeding World Health Organization and national standards. Despite this, local-scale exposure information beyond urban centers, in...

Quantitative evaluation of vulnerability and resilience in Indian meteorological hazards using correlation, clustering, PCA, and random forest

Meteorological disasters in India impose multidimensional impacts that span human casualties and fiscal recovery gaps. This study applied an integrated framework combining correlation analysis, clustering, principal component analysis (PCA), composite indices, and Random Forest r...
