Abstract

We present a temporal stability study of the calibration coefficients of two nonlinear calibration functions which are used for temperature retrievals in the pure rotational Raman (PRR) lidar technique. These functions represent the special cases of the general calibration function that takes into account the collisional broadening of all N₂ and O₂ PRR lines in the troposphere. The coefficients stability is studied on the examples of vertical tropospheric temperature profiles (3–9 km) retrieved on 1, 6, 7, and 8 April 2015. The temperature profiles were retrieved from nighttime lidar measurements made in Tomsk (56.48° N, 85.05° E, Western Siberia, Russia) using the IMCES PRR lidar. The lidar was developed in the Institute of Monitoring of Climatic and Ecological Systems of the Siberian Branch of the Russian Academy of Sciences (IMCES SB RAS). The validity of usage of the calibration coefficients averaged over some period of monitoring for temperature profile retrievals is discussed.
