Abstract
The purpose of this work is to measure the ozone vertical distribution (OVD) in the upper troposphere–stratosphere by differential absorption lidar (DIAL) at 299/341 nm and 308/353 nm and to compare and analyze the results against satellite data. А lidar complex for measuring the OVD in the altitude range ≈(5–45) km has been created. Here we analyze the results of ozone lidar measurements at wavelengths of 299/341 nm and 308/353 nm in 2018 at Siberian Lidar Station (SLS) and compare them with satellite (MLS/Aura and IASI/MetOp) measurements of OVD. The retrieved lidar OVD profiles in the upper troposphere–stratosphere in comparison with MLS/Aura and IASI/MetOp profiles, as well as the stitched OVD profile in comparison with the mid-latitude Krueger model, confirm the prospects of using the pairs of ozone sounding wavelengths 299/341 and 308/353 nm.
Highlights
Laser sounding, which has been developing since the invention of the laser in 1961, takes rank as a leading remote sounding technique
The present paper shows the continuation of the comparison of lidar and satellite monitoring [16] for upper troposphere–stratosphere altitudes of ≈5–45 km
We receive IASI ozone profiles from the IAO SB RAS satellite data receiving station with spatial resolution from ≈150 m in the surface layer to several kilometers in the stratosphere and higher [27]
Summary
Laser sounding, which has been developing since the invention of the laser in 1961, takes rank as a leading remote sounding technique. Measurements in the stratosphere at the Siberian Lidar Station showed the top boundary of stratospheric sounding altitude to be ≈40–45 km; when using the pair of wavelengths. The use of lidar complexes (Table 1) with different parameters of lasers, makes it possible to effectively select the high-altitude sensing range and investigate the vertical distribution of ozone. Tsukuba lidar stations and Yangbajing Observatory have already been carried out [15,18,19,20], but up to this point there has been no comparison of MLS with data obtained on the SLS, the territory of Western. The purpose of our work was to compare and analyze the lidar and satellite measurements of the ozone vertical distribution (OVD) in the altitude range ≈(5–45) km (upper troposphere–stratosphere) for annual and seasonal ozone variations. Similar comparisons with the IASI were made with ozone probes in 2010 at McMurdo Station, Antarctica [21] and in 2015 with the lidar at SLS [19]
