Product Description
Aerosol particles in the atmosphere
directly influence the earth’s radiative
balance by absorbing and scattering the
solar radiation and indirectly, by changing
the clouds microphysical properties.
The amount of sunlight reaching the earth’s surface,
rather than being scattered back to space, is an important
parameter to accurately model the influence of aerosol
scattering on the earth’s radiative balance.
The Aurora™ 3000 provides this measurement by reporting
both the integrated and back-scattered coefficient.
Using a LED light source, the Aurora™ 3000 simultaneously
measures at 525 nm (green), 450 nm (blue) and 635
nm (red) to enable wide and in-depth analysis of the
interaction between light and aerosols.
The ACOEM Ecotech Aurora™ 3000 includes backscatter
measurements that allows both standard integrating
measurements of 9 - 170° and also the back scatter 90 - 170°.
APPLICATIONS
• Studies on backscatter and forward scatter
• Scattering enhancement factor (eg. in combination with the
Ecotech ACS)
• Scattering Angstrom exponent calculations
• Determination of single scattering albedo
• Easy integration with the ACOEM ACS 1000.
BENEFITS
• Simplified automatic calibration using internal valves, ideal for
remote locations
• Fully automatic zero check or adjust, automatic span check
or automatic zero and span check available in intervals of
1, 3, 6, 12, 24 hrs or weekly
• Fully integrated package including internal sample pump, sample
heater, internal calibration valves, zero air pump and data logger
• Internal sample heater with temperature or RH control, which
can be enabled by the user to eliminate the effects of humidity
(RH: < 30 to < 90 % )
• 12 VDC operation (60 watts max, 14 watts nominal)
• Holds up to 33 days of 5 minute data averages, 6 days of 1 minute
data, or every measurement cycle (3 seconds)
• Our LED light source is guaranteed not to fail within 3 years, and
often exceeds 5 years
• An LED light source uses the same light path for each wavelength
ensuring consistency of measurement, eliminating the need for
PMTs and band pass filters maximizing light intensity
• Remote control through serial interface
• Suitable for high altitude applications.
