Short summary
Snow and ice samples were collected from six glaciers and multiple mountain valleys from northern Pakistan. Samples were analyzed for black carbon and water-insoluble organic carbon. Relatively high concentrations of black carbon, organic carbon, and dust were reported. Snow albedo and radiative forcing were estimated for the snow samples. Possible source regions of pollutants were identified through various techniques.
