Airborne measurements of vertical profiles of aerosols over Indian mainland are conducted as part of Regional Aerosol Warming Experiment. The airborne experiments are conducted onboard a twin turbo propeller aircraft, Super King Beechcraft 200, of National Remote Sensing Centre, Hyderabad. The first phase of the experiments was during the winter period (17 November to 30 December, 2012) over distinct regions from 7 bases, when the aerosols have longer lifetime, confined by the shallow winter atmospheric boundary layer and the atmosphere is dry with weak to moderate thermal convection. The pre-monsoon phase of the campagin started from Hyderbad during the pre monsoon season (25 April - 25 May, 2013) when the solar heating is high enabling strong convection and vertical transport of aerosols to the higher altitude. Measurements included vertical profiling up to an altitude of ~3000m AGL over the respective regions and the horizontal flights at 1500/ 3000m AGL connecting the base stations measuring spatial gradients. Measurements employed a suite of instruments: Aethalometer, Nephalometer, Aerodynamic Particle sizer, Optical Particle Counter, Photoacoustic soot spectrometer, dust track, Cloud condensation nuclei counter, Aerosol total particle counter etc. over distinct geographical environments. Gestated from ICARB, RAWEX focuses on
