GOMOS stratosphere AERGOM CCI
 |
 |
Gridded stratospheric aerosol records retrieved using the improved GOMOS retrieval algorithm AerGom, including extinction and stratospheric aerosol optical depth. Makes use of a 3D grid with resolution 10° longitude x 2.5° latitude x 1 km height monthly means. The retrieval algorithm uses an improved spectral parameterization of the aerosol quantities with respect to GOPR. Minimization by a Levenberg-Marquardt algorithm with Tikhonov regularization. All products provided with estimates of the uncertainty.
