“…Atmosphere 2024, 15, 629 2 of 13 Based on satellite observations and model simulations, it has been determined that INPs play a crucial role in influencing the phase of clouds [18]. INPs have the potential to mix, adsorb, coagulate, or undergo chemical reactions with other substances (such as biological materials, anthropogenic emissions, and secondary products) due to human actions [19,20]. These coatings or reactive substances may alter the ability of INPs to initiate ice formation, thus impacting the creation of clouds and their microphysical properties [21,22].…”

Atmospheric ice nucleation particles (INPs) play a crucial role in influencing cloud formation and microphysical properties, which in turn impact precipitation and Earth’s radiation budget. However, the influence of anthropogenic activities on the properties and concentrations of INPs remains an area of significant uncertainty. This study investigated the physical and chemical characteristics of atmospheric ice nucleation particles in Huangshan, China during the May Day labor holiday period (spanning 8 days, from April 27th to May 5th). INP concentrations were measured at temperatures from −17 °C to −26 °C and relative humidities (RHw) from 95% to 101%. Average INP concentrations reached 13.7 L−1 at −26 °C and 101% RH, 137 times higher than at −17 °C and 95% RH. INP concentrations showed exponential increases with decreasing temperature and exponential increases with increasing RH. Concentration fluctuations were observed over time, with a peak of ~30 L−1 (t = −26 °C, RHw = 101%) around the start and end of the holiday period. Aerosol number concentrations were monitored simultaneously. The peak in aerosols larger than 0.5 μm aligned with the peak in INP concentrations, suggesting a link between aerosol levels and INPs. Chemical composition analysis using SEM–EDX revealed the distinct elemental makeup of INPs based on the activation temperature. INPs active at warmer temperatures contained N, Na, and Cl, indicating possible biomass and sea salt origins, while those active at colder temperatures contained crustal elements like Al and Ca.

“…In high mountain glacier areas, the high reflectivity of snow causes the retinas of humans who are not wearing sunglasses to be irritated by bright light, which can cause minor eye pain or temporary blindness, a phenomenon known medically as “snow blindness” 6 , 7 . Natural light is closely linked to human health 8 – 11 , with Rosenthal first suggesting in 1984 that a lack of natural light can cause a range of problems in the body, of which seasonal affective disorder (SAD) is a typical example 12 . Human biorhythms are influenced by light, which controls the secretion of melatonin by the pineal gland, which in turn affects sleep and mood 13 , 14 .…”

Light climate environment (LCE) has a significant impact on human health, behavioral characteristics, and the safety of life and property due to the high albedo of snow on the ground cover type, which in turn affects the regional climate and socio-economic development, but less relevant studies have been found. In this study, the effect of snow on daytime and nighttime light levels was quantified using comparative field observations and controlled experiments in artificial climate chambers, combined with analysis of variance and model fitting. The results of the study found that there was a significant difference between the presence and absence of snow on both daytime and nighttime light levels. During daytime, the ambient light level on the ground with snow is 5.68 times higher than without snow, an improvement of 12,711.06 Lux. At night, with moonlight, the nighttime illuminance with and without snow is 0.213 Lux and 0.01 Lux, respectively. When there is no moonlight, the snow has no significant effect on the light level. In addition, significant differences in LCE intensity with different snow depths, snow densities and black carbon (BC) pollution. At the same background light intensity, the LCE intensity varies significantly with increasing snow depth, snow density and BC pollution. The results reveals the quantitative impact of snow on LCE, providing scientific support for regional natural light energy use, human health and safety, urban environmental management and economic development.

Snow particles physiochemistry: feedback on air quality, climate change, and human health

Abstract: During the last several decades, numerous researchers have provided evidence that physical and biogeochemical processes at air-snow/ice-water interfaces are very complex and, in many cases, interlinked. This review focuses on...
