Abstract
Работа посвящена исследованию зависимостей характеристик солнечной радиации от оптических моделей атмосферы земли, а также оцениванию вклада аэрозоля в ослабление потока прямой солнечной радиации. Для расчетов характеристик солнечной радиации в атмосфере отраженного и пропущенного потоков солнечного излучения, лучистого притока тепла, радиационного форсинга, полученных на основе данных наблюдений оптической толщины атмосферы, с помощью лидарного комплекса Ресурсного Центра «Обсерватории экологической безопасности» Научного парка СПбГУ в городе Санкт-Петербург была построена оптическая модель атмосферы. Расчеты характеристик солнечной радиации проводились с использованием метода Эддингтона. Полученные значения потоков солнечной радиации сравнивались с синхронными актинометрическими данными, которые показали хорошее совпадение результатов.
The work is devoted to the investigation of the dependence of the solar radiation characteristics on the optical models of the earth's atmosphere, as well as to the estimation of the aerosol contribution to the weakening of the direct solar radiation flux. To calculate the characteristics of solar radiation in the atmosphere of reflected and missed solar radiation fluxes, radiant heat influx, radiation forcing, obtained from observational data of the optical thickness of the atmosphere, with the help of the lidar complex of the Resource Center "Observatory of Ecological Safety" of the St. Petersburg State University Scientific Park in St. Petersburg an optical model of the atmosphere was constructed. Calculations of the characteristics of solar radiation were carried out using the Eddington method. The obtained values of solar radiation fluxes were compared with synchronous actinometric data, which showed good agreement of the results.
