| description | Subject and Purpose. Analysis of ways to increase the accuracy of determining the parameters of the Earth’s atmosphere through the improvement of the ground-based spectral radiometric complex designed for monitoring carbon monoxide (CO) by millimeter radio wave radiation control, which was developed at the Institute of Radio Astronomy of the National Academy of Sciences of Ukraine The purpose is achieved by reducing the measurement errors of the emission amplitude of the observed tracer gas through the operational determination of the absorption of radio waves in the troposphere. By performing a rapid calibration of the troposphere opacity and promptly accounting for changes in radio signal absorption, we increase the accuracy and reliability of measurements of atmospheric CO radio emission intensity. This method is suitable for any systems of this type. By studying the frequency stability of local oscillators of all stages of frequency conversion in the receiving system, the maximum error in measuring stratospheric wind speeds at altitudes from 20 to 80 kilometers was determined.Methods and Methodology. The improved CO-monitoring setup measures radiometric atmospheric profiles, from which a new data processing method introduced in the paper quickly derives the antenna scattering coefficient. Then, the tropospheric absorption of the radio signal is evaluated immediately during monitoring in near-real time.Results. The CO-monitoring spectroradiometric complex has been upgraded and improved, enabling the measurement of radiometric atmospheric profiles and providing a prompt, near-real-time determination of the antenna scattering coefficient (previously unavailable). It has been demonstrated that monitoring the antenna scattering coefficient enhances the determination accuracy of the CO emission line amplitude, thereby increasing the reliability and validity of the obtained results. The studies related to the modernization of the monitoring instrument helped us evaluate the accuracy of measuring stratospheric wind speeds.Conclusion. Practical work and evaluations have proved that measuring tropospheric opacity directly during observations is feasible and significantly increases the accuracy and reliability of the results.Keywords: millimeter waves, aeronomy, measurement accuracyManuscript submitted 06.10.2025Radio phys. radio astron. 2026, 31(1): 003-010REFERENCES1.

Аналіз шляхів підвищення точності визначення параметрів земної атмосфери через вдосконалення розробленого в Радіоастрономічному інституті НАН України спектрального радіометричного комплексу наземного базування, призначеного для моніторингу монооксиду вуглецю (СО) по випромінюванню міліметрових радіохвиль. Мета досягається шляхом зменшення похибок вимірювання амплітуди випромінювання спостережуваного трасерного газу через оперативне визначення поглинання радіохвиль у тропосфері. Здійснюючи швидке калібрування непрозорості тропосфери та оперативно враховуючи зміни, що відбуваються в поглинанні радіосигналу, ми підвищуємо точність і достовірність вимірювань інтенсивності радіовипромінювання атмосферного СО. Цей метод придатний для будь-яких систем подібного типу. Через дослідження стабільності частоти гетеродинів усіх ступенів перетворення частоти в приймальній системі визначено величину максимальної похибки при вимірюванні швидкостей стратосферних вітрів на висотах від 20 до 80 кілометрів.Методи та методологія. У статті показано шляхи удосконалення системи моніторингу трасерного CO, за допомогою якого вимірюються радіометричні профілі атмосфери. Запропоновано новий метод обробки даних, що дозволяє швидко визначати коефіцієнт розсіювання антени. Надалі тропосферне поглинання радіосигналу оцінюється безпосередньо під час моніторингу в режимі, близькому до реального часу.Результати. Спектрорадіометричний комплекс для моніторингу трасерного CO було модернізовано та удосконалено, що дозволило вимірювати радіометричні профілі атмосфери й забезпечувати оперативне визначення коефіцієнта розсіювання антени (що раніше було неможливо) майже в режимі реального часу. Продемонстровано, що моніторинг коефіцієнта розсіювання антени підвищує точність визначення амплітуди лінії випромінювання CO, тим самим збільшуючи надійність і валідність отриманих результатів. Дослідження, пов’язані з модернізацією приладу моніторингу, допомогли нам оцінити точність вимірювання швидкості вітру в стратосфері.Висновки. Аналітично та на практиці доведено, що вимірювання непрозорості тропосфери безпосередньо під час спостережень є можливим і значно підвищує точність і надійність результатів.Ключові слова: міліметрові хвилі, аерономія, точність вимірюванняСтаття надійшла до редакції 06.10.2025Radio phys. radio astron. 2026, 31(1): 003-010БІБЛІОГРАФІЧНИЙ СПИСОК1.
