the Institute for Energy and Climate Research, Research Center
Juelich.In daily data set files following level 1 products
are included: (1) Doppler velocity: This is the motion of the
scattering target carried by the atmospheric flow along line of sight
(LOS) (2) attenuated backscatter coefficient: standard output provided
by the manufacturer, uncalibrated (3) error estimation for Doppler
velocity: theoretical uncertainty calculated using Cramer-Rao lower
bound (CRLB) as described in Pearson et al. (J. Atmos. Ocean.
Technol., 26, 240-250, 2009).Measurements only available if backscattering targets like
aerosol particles and cloud droplets are present with sufficient
quantity. Attenuated backscatter coefficient is uncalibrated.Original data together with quality flag and velocity error
are provided.50.90856.4135111noneDetails of the instrument and data processing can be

Lidar for Observing the Boundary LayerThe performance of the 1.5-mm pulsed Doppler lidar,
operated by the U.K. Universities Facility for Atmospheric
Measurement (UFAM) over a 51-day continuous and unattended field
deployment in southern England, is described and analyzed with a
view to demonstrating the capabilities of the system for remote
measurements of aerosols and velocities in the boundary layer. A
statistical assessment of the vertical pointing mode in terms of the
availability and errors in the data versus range is presented.
Examples of lidar data are compared to theoretical predictions,
radiosondes, the UFAM radar wind profiler, and an ultrasonic
anemometer.J. Atmos. Ocean. Tech., 26, 240-2502013A.J. Illingworth, D. Ruffieux, D. Cimini, U. Loehnert et al.COST Action ES0702 EG-CLIMET – Final Report,
