AERI Atmospheric Emitted Radiance Interferometer
Brand: ABB GroupThe Atmospheric Emitted Radiance Interferometer, or AERI™, is a ruggedized automated sounding spectroradiometer system for unattended operations in hostile ambient conditions.
It measures absolute down-welling atmospheric emitted infrared radiance with high accuracy.
Coupled with specialized algorithms, this remote sensing tool can work year-round during both day and night (except during precipitation), continuously providing temperature and humidity as other atmospheric variables profiles every 8 minutes.
Features- Mature technology: some installed systems have been continuously in operation for more than fifteen years
- High radiometric accuracy and reproducibility allowing network operation
- Wavelength accuracy with high spectral resolution
- High sensitivity
- Fast scanning capability with real-time spectral processing
Benefits
- NIST traceable radiometry
- Operation under all climates (Arctic to tropics and even marine)
- Unattended operation
- No consumable
- In field replacement of the Stirling cooler and metrology laser
- ITAR Free
