Mineral dust particles suspended in the atmosphere span more than three orders of
magnitude in diameter, from< 0.1 µm to more than 100 µm. This wide size range makes dust …

The ice giants Uranus and Neptune are the least understood class of planets in our solar
system but the most frequently observed type of exoplanets. Presumed to have a small rocky …

Abstract The underwater Hunga Tonga-Hunga Ha-apai volcano erupted in the early hours of
15th January 2022, and injected volcanic gases and aerosols to over 50 km altitude. Here …

In June 2019 a stratospheric eruption occurred at Raikoke (48∘ N, 153∘ E). Satellite
observations show the injection of ash and SO 2 into the lower stratosphere and an early …

Abstract Following the Hunga Tonga eruption (20.6° S, 175.4° W, mid‐January 2022), we
present a balloon‐borne characterization of the stratospheric aerosol plume one week after …

Akhil Raj, ST, M. Venkat Ratnam, D. Narayana Rao, and BV Krishna Murthy, 2015: Vertical
distribution of ozone over a tropical station: Seasonal variation and comparison with satellite …

The emission of greenhouse gases (GHGs) has changed the composition of the atmosphere
during the Anthropocene. Accurately documenting the sources and magnitude of GHGs …

In this study, we present a traceable method for determining the counting efficiency of optical
particle size spectrometers (OPSS), also known as aerosol spectrometers. The primary …

In the companion (Part I) paper, we have described and evaluated a new versatile optical
particle counter/sizer named LOAC (Light Optical Aerosol Counter), based on scattering …

We investigate the dust forecasts from two operational global atmospheric models in
comparison with in situ and remote sensing measurements obtained during the AERosol …
