The PollyXT-type lidar at the Remote Sensing Laboratory provides unique
data for the EARLINET/ACTRIS Data Base. Specifically, the delivered
profiles are evaluated for both day and nighttime solely with the
classical Raman retrieval. Moreover, those profiles comprise complete
sets of wavelength-dependent particle backscatter and extinction
coefficients and depolarization ratios (3β+2α+2δ), all averaged with the
same temporal and height resolution and smoothing. The number of data
files provided form July 2013 to December 2018 is impressive being of
1348 high-resolution, so-called, b-files and 851 low-resolution
e-files. Firstly, a short description of the EARLINET/ACTRIS Data Base
will be given, including discussion of the quality assurance procedures
and quality control tests, the uniqueness of the climatology category
measurements and the rules of providing the profiles to the database.
Then, the seminar will be focused on the Warsaw RS-Lab data and
evaluation chain, uncertainty estimation, as well as the results of
the international lidar intercomparison campaign which took place in
June 2018. Finally, the average Warsaw profiles derived over the
different categories in the EARLINET/ACTRIS Data Base will be discussed.
Slides will be in English, but the presentation will be in Polish.
