    Orbits: vertical ozone profiles from GOME-2

    The vertical ozone profiles indicate the presence of ozone in the atmosphere. The profiles are derived from the reflectances measured by GOME-2 between 265 and 330 nm. Taken into account are surface pressure and albedo, cloud data such as cloud top pressure, cloud fraction and cloud albedo. Below there are links to the vertical ozone profile products that are currently available from the ACSAF.

    Please note: GOME-2 L1b data comes in as 3 minute data packets (PDU's) which are processed in NRT (within 3 hours of sensing) but in order to ensure that the orbit stored in the archive is as complete as possible, the final concatenation of the NOP PDU's is done two days later. Data above has a delay of two days.


    The GOME-2 Offline Ozone Profile (OOP) is currently an operational product. Imagery is available from this website, but due to data policy restrictions the underlying datafiles are available via the EUMETSAT Data Center (see the ACSAF website for more information).
