Assessing Measurements of Pollution in the Troposphere (MOPITT) carbon monoxide retrievals over urban versus non-urban regions [PDF]

Atmospheric Measurement Techniques, 2020
The Measurements of Pollution in the Troposphere (MOPITT) retrievals over urban regions have not been validated systematically, even though MOPITT observations are widely used to study CO over urban regions. Here we compare MOPITT products over urban and

COMPARATIVE REVIEW OF CROATIAN AND INDIAN AIR POLLUTION STUDIES WITH EMPHASIS ON POLLUTANTS DERIVED BY COAL COMBUSTION

Rudarsko-geološko-naftni Zbornik, 2017
Human health, the environment, and climate are being profoundly aff ected by complex pollutant interactions in the atmosphere. Almost all human activities cause the emissions of air pollutants.

New seasonal pattern of pollution emerges from changing North American wildfires

Nature Communications, 2022
Growing emissions from Pacific Northwest wildfires have increased atmospheric carbon monoxide in August, raising questions about potential health impacts as the seasonal pattern of air quality changes for large regions of North America.

Changing patterns in aerosol vertical distribution over South and East Asia

Scientific Reports, 2021
Changing patterns in aerosol concentrations over the Asian region is well documented with a concurrent increase over India and a marked reduction over China. However, aerosol vertical distribution in the changing climate is not fully understood.

Mass‐Conserving Downscaling of Climate Model Precipitation Over Mountainous Terrain for Water Resource Applications

Geophysical Research Letters, 2023
A mass‐conserving method to downscale precipitation from global climate models (GCMs) using sub‐grid‐scale topography and modeled 700‐mb wind direction is presented.

Atmospheric methane removal: a research agenda

Philosophical Transactions of the Royal Society A, 2021
Atmospheric methane removal (e.g. in situ methane oxidation to carbon dioxide) may be needed to offset continued methane release and limit the global warming contribution of this potent greenhouse gas.

ROAM: a Radial-basis-function Optimization Approximation Method for diagnosing the three-dimensional coronal magnetic field

Frontiers in Astronomy and Space Sciences, 2016
The Coronal Multichannel Polarimeter (CoMP) routinely performs coronal polarimetric measurements using the Fe XIII 10747 $AA$ and 10798 $AA$ lines, which are sensitive to the coronal magnetic field.

High Climate Sensitivity in the Community Earth System Model Version 2 (CESM2)

Geophysical Research Letters, 2019
The Community Earth System Model Version 2 (CESM2) has an equilibrium climate sensitivity (ECS) of 5.3 K. ECS is an emergent property of both climate feedbacks and aerosol forcing.
