The interannual and seasonal dynamics of ions and trace elements in the aerosol composition is analyzed in detail. A 1.5-fold increase in the annual mean total ion concentrations is traced. The growth of the sum of ions was mainly due to the concentrations of Na+ and Cl− ions of marine origin, the content of which is minimal in summer and maximal in winter. The variations in the concentrations of nonmarine ions ({text{NH}}_{4}^{ + },) K+, Ca2+, F–, ({text{NO}}_{2}^{ - },) and ({text{NO}}_{3}^{ - }) differed from the seasonal course of Na+ and Cl− concentrations: the former decreased during the transition from winter to spring and increases in summer with a subsequent decrease in autumn against the background of an increase in the sum of ions due the marine ions. The ion composition of aerosols is formed under the effect of the marine factor, air mass transport, underlying surface, and wildfires. Among trace elements, Fe, Al, Zn, Mn, Sn, Cr, and Cu dominated with high concentrations in the fall and winter periods. Based on enrichment factors, elements of terrigenous (Al, Ti, Mn, Fe, Th, and U), mixed terrigenous and nonterrigenous (Li, Be, V, Co, Sr, and Ba), and nonterrigenous origin (Ni, Cu, Zn, Cr, Mo, Mo, W, Ag, Tl, Pb, As, Se, Cd, Sn, and Sb) are identified. The highest contribution to the total level of air pollution is made by Fe and Mn in winter and autumn and by Fe and Be in spring and summer. Among nonterrigenic elements, Cu, Sn, Zn, Se, and Ni contributed the most in all seasons. The level of air pollution with trace elements is assessed as low at the Cape Baranov Ice Base station.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140800077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The global unitary variation in the ionospheric potential observed in the daily variation in the electric field is distorted under the electrode effect near the Earth’s surface. The structure of the resulting electrode layer strongly depends on the degree of turbulent mixing, the specific conductivity of air, and the altitude of electric field measurement. Based on the equation for the total electric current, which follows from the theory of the electrode effect of the surface air layer, we simulated daily variation in the electric field at different altitudes under different meteorological conditions. The simulation reveals the dependence of the position and magnitude of the global extreme points of the electric field on the turbulent mixing coefficient, air conductivity, and electrode layer height. Our results can be useful for solving applied problems in geophysics, in particular, atmospheric electric field monitoring.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140800024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is of special interest for atmospheric sounding, where turbulence can affect beam propagation. We experimentally study the effect of a turbulent layer produced at the beginning of a laser radiation propagation path on the characteristics of the filamentation domain and generation of high-intensity plasma-free channels for laser beams 2.5 and 5 cm diameter, including under the phase control of the transverse beam structure with a deformable mirror. In the presence of turbulence, the beginning of multiple filamentation domain approaches, however, insignificantly (<10% of the path length), a radiation source. More important is that a turbulent layer formed at the beginning of a path results in a multiple increase in the number of high-intensity (mean intensity is ∼1011–1012 W/cm2) light channels in a laser beam during its nonlinear propagation, which induce two-photon fluorescence of dyes at a distance of longer than 100 m from the radiation source with the signal level sufficient for its recording by a lidar scheme. This laser beam structure can be used for sounding natural and anthropogenic aerosols.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140800163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerical results agree well with the proposed semianalytical solution, in which the total contribution (atmospheric response) in the CH4 level at a given site is decomposed into direct (synoptic) and global terms. On an advection timescale corresponding to a synoptic time interval, the annual average direct contribution of Russian anthropogenic emissions into the CH4 mixing ratio measured at ZOTTO (38.6 ppbv) is more than twice as large as that for Western Europe sources (17.7 ppbv). For the Arctic sites, the anthropogenic inputs from Russian and European sources are roughly similar (19.5 and 12.4 ppbv, respectively). The input from continental sources into near-surface methane abundance and its annual variations at the Arctic sites are generally lower compared to those at the ZOTTO site due to larger transport times from upstream CH4 source regions. Model-based atmospheric responses in methane levels at the Teriberka and Tiksi sites to continental CH4 sources are found to be very close owing to the relatively homogeneous (circumpolar) spatial distributions of the anthropogenic and biogenic signals at high latitudes.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S1024856023700100.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140799981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
