Influence of Absorption Cross-Sections on Retrieving the Ozone Vertical Distribution at the Siberian Lidar Station

Abstract

The purpose of this paper is to study how the application of different sets of absorption cross-sections influence the ozone vertical distribution (OVD) in the upper layers of the troposphere—stratosphere in the altitude range ~(5–45) km, using a differential absorption lidar (DIAL), operating at the sensing wavelengths 299/341 nm and 308/353 nm. We analyzed the results of lidar measurements of OVD obtained in 2021 using meteorological data from the IASI/MetOp satellite at the Siberian Lidar Station (SLS). The retrieval was performed using the data of four groups concerning the absorption cross-sections: Gorshelev et al., Malicet et al., SCIAMACHY, and GOME. To estimate how the absorption cross-sections influence the OVD retrieval from lidar measurements, we calculated the average deviations between the profiles retrieved using different sets both in a particular case on 2 January 2021 and throughout 2021. Our study showed that, out of the four absorption cross-section sets, the data of Gorshelev et al. should be used for long-term lidar monitoring of the ozone. These data show a more discrete dependence of the absorption cross-sections on the temperature values, which is more urgent for tropospheric and stratospheric ozone measurements.

Development of mobile lidar for remote sensing of tropospheric ozone on the vertical and horizontal (slant) paths

“…This method is used actively at all lidar stations worldwide, where spatial ozone stratification is measured. It is based on the use of the equation from works [5,6]:…”

Temperature correction of ozone profiles using data from satellite and lidar sensing of the atmosphere

“…Zuev Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences we continue the multiyear ozone lidar studies in the upper tropospherelower stratosphere and stratosphere at the sensing wavelength pairs 299/341 nm (~5-20 km) and 308/353 nm (~15-45 km) 1 . The measurements are processed using the method for retrieving the lidar profiles of the ozone vertical distribution, taking into account the temperature 2,3 and aerosol corrections. It should be noted that lidar stations similar to SLS operate in different parts of the world: Tsukuba (36.05° N, 140.13° E), Japan 4,5 ; Observatoire de Haute Provence (OHP) (43.94° N, 5.71° E), France 6,7 ; Hefei (31.82° N, 117.22° E), China 8,9 ; Table Mountain Facility (TMF) (34.4° N, 117.7° W), USA 10,11 ; Goddard Space Flight Center (GSFC) (37.1° N, 76.39° W), USA 12,13 ; Vladivostok (43.3° N, 132° E), Russia 14 ; Yangbajing Observatory (30°5′ N, 90°33′ E), China 15 .…”

Multiyear lidar and satellite sensing of the atmosphere: stratospheric and tropospheric ozone profiles

“…Main specifications of laser sources and optical detecting elements of the lidar system are given below. The measurements are processed, using the method for retrieving the lidar profiles of the ozone vertical distribution (OVD), taking into account the temperature 14,15 and aerosol correction. The lidar measurements are compared with observations from Microwave Limb Sounder (MLS on the Aura satellite) 16,17 , Infrared Atmospheric Sounding Interferometer (IASI on the MetOp satellite) 18,19 , and Ozone Mapping and Profiler Suite (OMPS on the Suomi satellite) 20,21 .…”
