Air pollution is a global problem, which needs to be understood and controlled to ensure a
healthy environment and inform sustainable development. Urban areas have been …

Arctic climate change has already resulted in amplified and accelerated regional warming,
or the Arctic amplification. Satellite observations have captured this climate phenomenon in …

Warm boundary layer clouds in the eastern North Atlantic region exhibit significant diurnal
variations in cloud properties. However, the diurnal cycle of the aerosol indirect effect (AIE) …

The planetary boundary layer (PBL) is the lowermost part of the troposphere that governs
the exchange of momentum, mass and heat between surface and atmosphere. To date, the …

The lowest layer of the atmosphere in which all human activity occurs is called the Planetary
Boundary Layer (PBL). All physical interactions with the surface, such as heat and moisture …

Nitrogen oxides (NO x= NO+ NO 2) emissions are estimated in three regions in the Northern
Hemisphere, generally located in North America, Europe, and East Asia, by calculating the …

We have analyzed near-global stratospheric data (and mesospheric data as well for H 2 O)
in terms of absolute abundances, variability, and trends for O 3, H 2 O, HCl, N 2 O, and HNO …

Radiosondes are the most widely used method for studies of vertical atmospheric behavior,
but the high costs associated, and the logistic limitations have forced researchers to look for …

Notable warming trends have been observed in the Arctic, with tropospheric aerosols being
one of the key drivers. Here the seasonal cycles of three-dimensional (3D) distributions of …

Extreme smog in India widely impacts air quality in late autumn and winter months. While the
links between emissions, air quality and health impacts are well‐recognized, the association …
