| Zusammenfassung |
| A novel approach for the detection of cirrus clouds and the retrieval of
optical thickness and top altitude based on the measurements of the Spinning
Enhanced Visible and Infrared Imager (SEVIRI) aboard the geostationary
Meteosat Second Generation (MSG) satellite is presented. Trained with 8 000 000 co-incident measurements of the Cloud-Aerosol Lidar with Orthogonal
Polarization (CALIOP) aboard the Cloud-Aerosol Lidar and Infrared Pathfinder
Satellite Observations (CALIPSO) mission the new "cirrus optical properties
derived from CALIOP and SEVIRI algorithm during day and night" (COCS)
algorithm utilizes a backpropagation neural network to provide accurate
measurements of cirrus optical depth τ at λ = 532 nm and top
altitude z every 15 min covering almost one-third of the Earth's atmosphere.
The retrieved values are validated with independent measurements of CALIOP
and the optical thickness derived by an airborne high spectral resolution
lidar. |
