Special Issue Information

Dear Colleagues,

Aerosols from uptake by air and natural and anthropogenic emissions, and/or formed by gas-to-particle conversion from precursor gases, as well as radiatively active gases, are well known to influence the local energy balance and cloud and precipitation formation, with feedback to local atmospheric chemistry and composition. Aerosols from various sources can act as cloud condensation and/or ice nuclei. Their abundance, composition, and size affect, among other things, cloud lifetime and cloud radiative properties with feedback to local radiation including photolysis rates, chemical reaction rates, aerosol formation rates, and the local surface-energy budget, as well as biogenic and (potentially) anthropogenic emissions. Currently, the impact of atmospheric chemistry and its effect on weather and climate at the local scale are not well understood. However, most direct emission-control measures occur at the urban, local scale.

This Special Issue, "Impacts of atmospheric chemistry on local weather and local climate", will call for submissions of papers that demonstrate original research that can overcome current gaps in understanding the interactions between atmospheric chemistry on the one hand side and local weather, and hence local climate, on the other. Review articles are also welcome. The topics will include, but are not limited to examining, the following: (1) the modification of urban weather/climate due to emission and/or air quality changes, (2) the impact of Arctic or other haze on local temperature and moisture conditions, (3) the impact of local scale emission-control measures on local weather/climate, (4) the relationship between different local chemical regimes and local weather, and (5) the  impact of local indirect emission-control measures on the weather/climate in the adjacent downwind region. Studies analyzing data from air-quality modeling, monitoring networks, field experiments (ground-based, airborne), and remote sensing are equally welcome. Please send papers addressing climate forcing and/or global aspects to the regular issues of Climate.

According to modern concepts, the main natural sources of dust in the atmosphere are dust storms and associated dust devils—rotating columns of rising dust. The impact of dust and aerosols on climate change in the past, present and future is one of the poorly understood and, at the same time, one of the fundamental elements needed for weather and climate forecasting. The purpose of this review is to describe and summarise the results of the study of dust devils in the Earth’s atmosphere. Special attention is given to the description of the 3D structures, the external flows and atmospheric gradients of temperature that lead to the generation and maintenance of the dust devils.

Abstract: We investigate the ozone diurnal variation on September 6, 2013 under a midsize urban environment using multiple in situ and remote sensing measurements and a large-eddy simulation (LES) model coupled with a chemical module. Our study area is in Huntsville AL USA, a typical midsize city in the Southeastern United States. The ozone variation in the convective boundary layer (CBL) is mainly caused by local emissions and photochemical production due to weather conditions controlled by an anticyclonic system on that day. The local chemical production contributes over 2/3 of the ozone enhancement in the CBL. Dynamical processes, including ozone transport from the free troposphere (FT) to the CBL through the entrainment processes, contribute the remainder. The numerical experiments performed by the LES model show good agreement with ozone DIAL observations. However, simulation results and ozone DIAL observations fail to reproduce a declining trend of surface ozone measured by an EPA surface monitoring station that is 6 km south of the DIAL location. This difference may be due to the large ozone horizontal variation and the diurnal variation of ozone dry deposition in an urban environment. This study indicates a need for fine-scale, three-dimensional ozone observations with high temporal and spatial resolution for air quality studies at urban and smaller scales.
