High Resolution GOME-2 Vertical Ozone Profiles - Metop

Abstract:
The NRT vertical ozone profile product (NHP) provides 40 layers of subcolumn ozone amounts in BUFR format. The offline vertical ozone profile product (OHP), in HDF5 format, also provides the 40 layers of subcolumn ozone amount (in DU), but also a wealth of more detailed information, such as the full error covariance matrix, the retrieval noise covariance matrix, the a-priori profile of the averaging kernels and the retrieved auxiliary parameters, like surface or cloud albedo. Also included are: geolocation, spectral windows used and retrieval diagnostics, like number of iterations, spectral fit indicators. The ozone profile is reported as partial columns, in Dobson Units, between 41 pressure levels logarithmically spaced between and including surface pressure and 0.001 hPa. For cloudy and partially cloudy scenes, the cloud-top pressure replaces the nearest pressure level. The Tropospheric Ozone Column product (TrO3) from the sufrace to 500hPa (and from the surface to the tropopause) is given as a separate value in the HDF5 offline ozone profile product. Metop-A data are available in the Data Centre up to 15/11/2021.
