Summary: Agricultural fires result in half the amount of burned biomass compared to forest fires, but the social costs of burned biomass, including air pollution and the increase in crime, are significant. This study provides evidence on the causal relationship between air pollution and crime using the increased rice stubble burning in Pakistan as a natural experiment. The findings show that air pollution increases all crimes, with particular emphasis on violent crimes. Reduction in earnings for middle-aged and older male individuals is identified as an important potential mechanism, and psychological factors are also discussed. The social costs of burned agricultural biomass have wide-ranging implications for developing economies reliant on agriculture.

Summary: This paper proposes an effective method to improve the performance of the ORC-VCR system by improving the system configuration. The theoretical model of thermodynamic, economic, and environmental performance is constructed, and the proposed system is compared with the basic ORC-VCR system. The effects of operating parameters on the performance of the proposed system are investigated, and a comparison of system performance in different positions of phase transition temperature is carried out. The results show that the novel system has better thermodynamic performance but slightly worse economic performance compared to the basic system. The composition of the mixture also has a significant impact on system performance at different phase transition temperatures.

Summary: A prediction model for the dew-point temperature of the attached air layer of radiant ceiling cooling panels was investigated in this study, allowing for adjustment of panel temperature based on changes in indoor factors to prevent condensation. Experimental data verified the significant influence of factors such as distance from person to the attached air layer and number of people on the dew-point temperature. Results showed that the prediction model takes the form of a negative exponential function and the distance from person to the attached air layer has a strong impact on the increase rate and stable time of the air dew-point temperature.

Summary: This study investigates the sensitivity of daily and 30-minute precipitation extremes to temperature variables across different climate zones in China. The results show a mix of positive and negative scaling factors for extreme daily precipitation with surface air temperature (SAT), with peak structures observed at higher temperatures. Comparisons between different temperature ranges reveal that a single scaling rate is not applicable for the entire temperature range. The scaling factors based on the temperature range before the peak structure exhibit better agreement with the Clausius-Clapeyron scaling, except for the tropical region. Daily scaling factors based on IMERG data are generally comparable to CN05.1 results, with discrepancies mainly in tropical and plateau climates. However, the 30-minute precipitation extremes in IMERG data do not increase as expected with rising temperatures, indicating the need for another precipitation dataset for scaling at this timescale, at least for China's mainland.

Summary: In this study, a four-dimensional spatiotemporal deep forest model was used to estimate the chemical composition of PM2.5 in China. The results show that secondary inorganic aerosols (SIAs) are a major component of PM2.5, and their proportion has been decreasing in the eastern region. During the COVID-19 lockdown, there was a sharp decline in SIA concentrations and an increase in SIA-to-PM2.5 ratios, indicating enhanced atmospheric oxidation capacity and the formation of secondary particles.

Summary: Unprecedented land use and land cover change (LULCC) has occurred in China in the past two decades. This study quantifies the impact of LULCC on summer temperatures in urban and rural areas in Eastern China from 2003 to 2019. The results show that LULCC causes urban areas, especially new urban areas, to become warmer, while rural areas become cooler and greener. The analysis also reveals that reductions in latent heat play a dominant role in urban warming. The study highlights the importance of larger greenspaces and albedo management in urban areas as part of LULCC policies to alleviate temperature disparity between urban and rural areas.

Summary: Satellite measurements of tropospheric nitrogen dioxide (NO2) have been widely used to track anthropogenic NOx emissions, but the interpretation can be complicated due to the influence of the free tropospheric NO2 background. The study used a chemical transport model to better understand the sources and trends of background NO2 over the contiguous US (CONUS) and found that accounting for aerosol nitrate photolysis corrected the previous model underestimate of the background. Additionally, the increase in aircraft NOx emissions and contribution from wildfires were identified as important factors in the interpretation of satellite NO2 trends.

Summary: In this study, the information content of POLDER-3 and 3MI observations for aerosol retrievals and the corresponding parameters' posterior errors were comprehensively analyzed using the Bayesian theory. The results showed that the total degree of freedom for signal of aerosol retrievals is increased with the incorporation of 3MI. The retrieval accuracy of volume concentration and effective radius is high in fine dominant conditions, but gets lower in coarse dominant conditions. The advanced 3MI measurements can improve the retrieval uncertainties of POLDER-3.
