ATMOS
Atmospheric attenuation monitoring
ATMOS - Atmospheric attenuation monitoring
ATMOS is an atmospheric attenuation measurement system developed for CSP tower plants.It works autonomously, measuring the atmospheric transmittance value in real time.
ATMOS measurement is based on optical spectrum analysis, which allows to distinguish the origin of the attenuation. The system is based on a target screen that reflects sun radiation. Then, two telescopic optical devices measure the spectrum of the reflected radiation and calculate the attenuation of the differential path. The system wavelength range is 400-1630 nm.
ATMOS helps monitor efficiency losses due to atmospheric attenuation and allows to perform preliminary CSP plant location studies.
- Real time measurement
- Spectral measurement
- Solar-weight attenuation measurement with ISO 9050 standard
