The detection of traveling wave disturbances manifested in the 630 nm atomic oxygen airglow caused by the effect of the SURA facility was the goal of this analysis. Except for two cases, no differences were found between periods with and without the effect of radio emissions from the SURA facility on the ionosphere. On August 7 and 10, 2021, weak wave structures similar in form and subsequent behavior were detected; they were moving in opposite directions from the SURA facility site with a length of at least 400 km. On August 7, 2021, the estimated front velocity was ∼104 m/s to the southwest and ∼127 m/s to the northeast. On August 10, 2021, the front velocity was ∼71 m/s and ∼142 m/s along the same directions, respectively. No such structures with such behavior were recorded by us before. The complex analysis of the heliogeomagnetic and ionospheric data for the experimental session in August 2021, including the days when traveling wave structures were detected, is presented in the paper. Unfortunately, we cannot unambiguously associate the detected traveling wave structures with the pumping regime of the SURA facility at that time. The source of these wave structures is still unclear.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":"37 1 supplement","pages":"S199 - S207"},"PeriodicalIF":0.9,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688334","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 efficiency of laser excitation of PO molecules is estimated depending on the spectral parameters of radiation. It is established that the efficiency of excitation of the electronic transition B2Σ+ (({v}{kern 1pt} ') = 0) – X2Π (({v}{kern 1pt} '') = 0) of PO molecule is approximately an order of magnitude lower than that of A2Σ+ (({v}{kern 1pt} ') = 0) – X 2Π (({v}{kern 1pt} '') = 0) transition.

Under a leadership of DSc. professor K.S. Shifrin, a wide range of problems in ocean optics were investigated in 1969–1991: the theory of absorption and scattering of light in sea water, determination of the quantitative and qualitative composition of ocean suspension matter based on the characteristics of light scattering, etc. A significant contribution to the theory of underwater vision was also made by DSc I.M. Levin and other scientists. The results significantly contributed to hydrooptics and ensured progress in the development of technical means for observing underwater objects and the aquatic environment. The laboratory staff conducts expeditionary measurements of hydrophysical and hydrooptical characteristics in the seas of Russia. Based on the results of comprehensive research, highly effective remote optical methods for ocean sensing are being developed. In recent years, the laboratory has paid significant attention to the direct development and creation of technical means for remote sensing of the World Ocean – radiometric LiDAR systems.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":"37 1 supplement","pages":"S11 - S17"},"PeriodicalIF":0.9,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688414","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}

MODIS satellite images of a site with coordinates (50.1°–50.4° N, 90.1°–90.7° E) are used as an example to assess the difference in the results obtained with the suggested algorithm with accounting the ground surface reflectance heterogeneity and rugged topography and neglecting the rugged topography, with the MOD09 algorithm, and with the algorithm without atmospheric correction. The results provided by the suggested algorithm and the MOD09 algorithm well agree. It is shown that the neglect of the rugged topography in the suggested algorithm for the images under study slightly underestimates the reflectance by Δrsurf ≤ 3.46 × 10−3 for MODIS band 1, 2.39 × 10−3 for MODIS band 2, 7.12 × 10−3 for MODIS band 3, and 5.23 × 10−3 for MODIS band 4.
