Aerosols at the poles: an AeroCom Phase II multi-model evaluation
Atmospheric aerosols from anthropogenic and natural sources reach the polar regions through long-range transport and affect the local radiation balance. Such transport is,...- publication PDF

Day-to-day ionospheric variability due to lower atmosphere perturbations
Ionospheric day-to-day variability is a ubiquitous feature, even in the absence of appreciable geomagnetic activities. Although meteorological perturbations have been recognized...- publication PDF

Multiwavelength high-resolution observations of chromospheric swirls in the quiet sun
We report observations of small-scale swirls seen in the solar chromosphere. They are typically 2 Mm in diameter and last around 10 minutes. Using spectropolarimetric...- publication PDF

Interpreting precession-driven δ18O variability in the South Asian monsoon region
Speleothem records from the South Asian summer monsoon (SASM) region display variability in the ratio of O-18 and O-18 (delta O-16) in calcium carbonate at orbital frequencies....- publication PDF
