This dataset contains Black carbon (BC) concentrations in ugm-3 measured with an Aethalometer model AE31 made during the Pre- Monsoon and Post-Monsoon periods of the APHH Delhi campaigns in 2018 at Indira Gandhi Delhi Technical University for Women (IGDTUW) site. The data has been corrected following the Weingartner method. Absorption coefficients were calculated following the Sandradewi model to determine biomass burning and fossil fuel contributions in Mm-1. The measurements were collected at a height of 4m. The data were collected as part of the DelhiFlux project part of Air Pollution & Human Health in a Developing Indian Megacity (APHH-India) programme.

Data were collected on the 27th of November 2008 and on 5th of January 2009 by the University of Manchester multi-angle absorption photometer at Chilbolton site in support of the FAAM campaign in the South-West of the UK. The dataset contains measurements of concentrations of black carbon mass loadings based on aerosol optical absorption. The data were collected for use in the CLOUDS project, which is one of multiple projects within the APPRAISE (Aerosol Properties, PRocesses And Influences on the Earth's climate) programme.

This dataset contains Black carbon (BC) concentrations in ugm-3 measured with an Multi Angle Absorption Photometer (MAAP) made during Post-Monsoon period of the APHH Delhi campaign in 2018 at Indian Meteorological Department (IMD) site. The measurements were collected at a height of ~ 26m. The data has been corrected following the Weingartner method. Absorption coefficients were calculated following the Sandradewi model to determine biomass burning and fossil fuel contributions in Mm-1. The measurements were collected at a height of 4m. The data were collected as part of the DelhiFlux project part of Air Pollution & Human Health in a Developing Indian Megacity (APHH-India) programme.

This dataset contains black carbon concentrations using the aethalometer AE33 monitor. Measurements were made at the Indira Gandhi Delhi Technical University for Women (IGDTUW), India. Concentrations are reported in micrograms per cubic centimetre (ug.cm-3). The stationary inlet was located on the roof of a 4-storey building at IGDTUW campus. The data were collected over two measurement periods (i) winter: 17/01/2018 - 09/02/2018 and (ii) pre-monsoon: 02/05/2018 - 25/05/2018, by the University of Birmingham. These data were collected as part of the ASAP-Delhi project as part of the Atmospheric Pollution and Human Health in an Indian Megacity (APHH) programme.
