- Atmospheric Emitted Radiance Interferometer (AERI) from ABB

The 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.

This multifunctional instrument lends itself to numerous remote sensing applications:

• Thermodynamic atmospheric research
• Spectroscopic science
• Cloud and aerosol studies
• Trace gas detection
• Land and ocean surface characterization
• Air quality monitoring (pollution)
• Weather forecasting
• Validation of satellite sounders
• Climate change monitoring
• Airport monitoring, etc.
• Weather monitoring

AERI remote sensing instrument is capable of retrieving the atmospheric vertical profiles of water vapor and temperature in unattended operation 24 h/day, 7 days/week, and 365 days/year operation.

Mobile AERI

A trailer was designed for this instrument to travel and take measurements wherever we want. The trailer is powered by a power generator and is having a heating system and air conditioning.
