Measurements of ozone vertical profiles in the upper troposphere-stratosphere over western Siberia by DIAL, MLS, and IASI

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. A 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.
