Enhanced light-absorption of black carbon in rainwater compared with aerosols over the northern Indian Ocean

Krishnakant Budhavant, August Andersson

The dataset includes mass concentrations of black carbon, organic carbon, water-soluble organic carbon and water-soluble ions measured in aerosols and rainwater over the northern Indian Ocean, at the Maldives. It also includes the data of mass absorption cross-section of black carbon for the measured samples (May 2014 to April 2015). The data will be useful to know the impact of black carbon on cloud formation and change in the hydrological cycle over the studied region.

Data description

Data are provided in one xlsx file that contains three sheets: metadata, aerosol chemical composition and rainwater chemical composition. The same data are also provided in three comma-separated value (csv) files.

Site coordinates: 6.77° N, 73.18° E. Black carbon (BC) is here quantified as elemental carbon (EC) using the NIOSH5040 protocol.
