RAE-1 RASS Extension
The Scintec RAE-1 RASS
Extension provides accurate
temperature profiles
in the atmospheric boundary
layer with high spatial
resolution. It is easily
implemented into an existing
Scintec FAS Series
sodar system, replacing
for meteorological towers
and tethered balloons.
Produsent/Leverandør: ScintecExtension provides accurate
temperature profiles
in the atmospheric boundary
layer with high spatial
resolution. It is easily
implemented into an existing
Scintec FAS Series
sodar system, replacing
for meteorological towers
and tethered balloons.
The sodar part of the
RASS emits acoustic pulses
into the atmosphere.
Electromagnetic waves,
emitted by the radio part,
are scattered at the soundwaves.
At the reception of
the scattered radio signal,
a Doppler shift emerges.
Making use of the dependence
of the speed of
sound on air temperature,
the temperature profile is
derived.
The Scintec RAE-1 RASS
Extension characteristics
include:
ultra-stable quartz
based frequency synthesizer
extremely narrow-band
receiver
longer range through extended
acoustic sweep
increased range-gating
accuracy by numerical
inversion procedure
implemented geometric
path correction
compact and easy to
move
low power consumption
