Vaisala LAP®-3000 and optional RASS for mesoscale observations.

Lower Atmosphere Wind
Profiler for your needs

The Vaisala LAP®-3000 is a Doppler
beam swinging wind proler that
reliably provides continuous and
frequent proles of horizontal wind
speed and direction and vertical
velocity up to 3 km above ground
level (agl). An extended antenna
aperture option improves the proler
performance by narrowing beam
width, increasing gain and reducing
side lobes of the antenna array.

When an optional Radio Acoustic
Sounding System (RASS) is added to
the Vaisala LAP
virtual temperature proles up to 1.5
km agl. These altitudes are maximum
values and will change dramatically
depending on atmospheric
conditions, proler conguration,
installation location and surrounding
environment. The LAP
ates fully unattended and provides

®

-3000, it will provide

®

-3000 oper-

continuous data with high vertical
and temporal resolution.

Software that suits yours
application

The Vaisala LAP®-3000 wind proler
control and signal processing
software, LAP-XM
multi-core processor in the Windows
operating system. LAP-XM
user dened conguration of the
sampling parameters, signal proc­essing and quality control algorithms,
and multiple congurable data
output formats, to provide customers
location and application specic
proler operation.

Up to one-year of wind and/or virtual
temperature data may be stored on
the radar processor. Averaged time
series, spectra, and moments data
can also be archived.

The Vaisala LAP
developed under a Cooperative

National Oceanic and Atmospheric
Administration (NOAA). Over 130
