Methodology for the independent calibration of Raman backscatter water-vapor lidar systems

Abstract: We present a method for the independent calibration of Raman backscatter water-vapor lidar systems. Particular attention is given to the resolution of instrumental changes in the short and the long terms. The method reposes on the decomposition of the instrument function, which allows the lidar calibration coefficient to be re-expressed as the product of two terms, one describing the instrumental transmission and detection efficiency and the other describing the wavelength-dependent convolution of the Raman ba… Show more

“…Calibration of water vapor Raman lidar measurements has been extensively discussed in the past (e.g., Vaughan et al, 1988;Sherlock et al, 1999b;Whiteman et al, 2003;. There are two main approaches: One approach consists of calculating every single term of Eq.…”

“…In theory, this factor could be derived from first principles (e.g., Sherlock et al 1999). However, due to the uncertainty in the Raman cross-sections and the transmission of the optics in CARL, the ARM program calibrates the lidar such that the integrated water vapour agrees with that retrieved from a two-channel microwave radiometer (Turner and Goldsmith 1999).…”

“…At the CNR-IMAA, particular care has been devoted to the calibration of Raman lidars, which is crucial to achieve high accuracy in water vapour profiling. Details on calibration procedures and related accuracy can be found in the literature (Sherlock et al, 1999;Turner and Goldsmith, 1999;Whiteman, 2003). The CNR-IMAA Raman lidar for the water vapour measurements has been calibrated with simultaneous and co-located radiosoundings during an intensive measurement campaign performed in May-June 2002.…”
