ASSIST II - Atmospheric Sounder Spectrometer by Infrared Spectral Technology
The most advanced ground-based atmospheric sounder
ASSIST II is the field deployable, turn-key sounder that the atmospheric community was waiting for. It is the first product that includes a self-calibrating spectroradiometer, a network-enabled control software that can operate from anywhere in the world and an integrated data processing pipeline that generates the end products that you need, autonomously.
Benefits
- Works out of the box - Highly integrated hardware and software (Edgar) solution
- Trust your results - End-to-end performance validated in the field
- Manipulate less data - Produces atmospheric parameter profiles, not only interferograms or spectra
- See further - Highest sensing performance available
- Use less manpower - True unattended 24/7 operation
- Work from anywhere - 100% remotely controllable
Features
- Measures temperature, water vapor and ozone vs altitude
- Can also measure CO2, CO and CH4 and several other gases
- High accuracy measurements for weather applications
- High vertical resolution and high temporal resolution
- Integrated and automatic radiometric calibration
- Extensive instrument health monitoring
- Network-centered architecture
- Extensive remote monitoring for maintenance
- Accepts additional user devices via the built-in USB, LVDS, and CameraLink interfaces
- Rugged construction (field deployable)
