We present LIVAS (LIdar climatology of Vertical Aerosol
Structure for space-based lidar simulation studies), a 3-D multi-wavelength global aerosol and cloud
optical database, optimized to be used for future space-based lidar
end-to-end simulations of realistic atmospheric scenarios as well as
retrieval algorithm testing activities. The LIVAS database provides averaged
profiles of aerosol optical properties for the potential spaceborne laser
operating wavelengths of 355, 532, 1064, 1570 and 2050 nm and of cloud
optical properties at the wavelength of 532 nm. The global database is based
on CALIPSO observations at 532 and 1064 nm and on aerosol-type-dependent
backscatter- and extinction-related Ångström exponents, derived from
EARLINET (European Aerosol Research Lidar Network) ground-based measurements for the UV and scattering calculations
for the IR wavelengths, using a combination of input data from AERONET,
suitable aerosol models and recent literature. The required spectral
conversions are calculated for each of the CALIPSO aerosol types and are
applied to CALIPSO backscatter and extinction data corresponding to the
aerosol type retrieved by the CALIPSO aerosol classification scheme. A cloud
optical database based on CALIPSO measurements at 532 nm is also provided,
neglecting wavelength conversion due to approximately neutral scattering
behavior of clouds along the spectral range of LIVAS. Averages of particle
linear depolarization ratio profiles at 532 nm are provided as well.
Finally, vertical distributions for a set of selected scenes of specific
atmospheric phenomena (e.g., dust outbreaks, volcanic eruptions, wild fires,
polar stratospheric clouds) are analyzed and spectrally converted so as to
be used as case studies for spaceborne lidar performance assessments. The
final global data set includes 4-year (1 January 2008–31 December 2011)
time-averaged CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) data on a uniform grid of 1° ×
1° with the original high vertical resolution of CALIPSO in order to ensure
realistic simulations of the atmospheric variability in lidar end-to-end
simulations. |
