Long-term measurements (from August 2009 to December 2014) of aerosol black carbon mass concentration (MBC) and spectral aerosol optical depth (AOD) were carried out from a high-altitude location, Hanle in western trans-Himalaya as part of the Regional Aerosol Warming Experiment.
Extensive measurements of columnar aerosol optical depth (AOD), composite (MT) and black carbon aero-
sol mass (MB) concentrations were made over the tropical Indian and Southern Oceans as a part of the
Pilot Expedition to the Southern Ocean during the boreal winter. The AOD, MT and MB show large lati-
