Overview of the O3M SAF GOME-2 operational atmospheric composition and UV radiation data products and data availability

[摘要] The three Global Ozone Monitoring Experiment-2 instruments will provideunique and long data sets for atmospheric research and applications. Thecomplete time period will be 2007–2022, including the period of ozonedepletion as well as the beginning of ozone layer recovery. Besides ozonechemistry, the GOME-2 (Global Ozone Monitoring Experiment-2) products areimportant e.g. for air quality studies, climate modelling, policy monitoringand hazard warnings. The heritage for GOME-2 is in the ERS/GOME andEnvisat/SCIAMACHY instruments. The current Level 2 (L2) data cover a widerange of products such as ozone and minor trace gas columns (NO₂, BrO,HCHO, H₂O, SO₂), vertical ozone profiles in high and low spatialresolution, absorbing aerosol indices, surface Lambertian-equivalentreflectivity database, clear-sky and cloud-corrected UV indices and surfaceUV fields with different weightings and photolysis rates. The SatelliteApplication Facility on Ozone and Atmospheric Chemistry Monitoring (O3M SAF)processes and disseminates data 24/7. Data quality is guaranteed by thedetailed review processes for the algorithms, validation of the products aswell as by a continuous quality monitoring of the products and processing.This paper provides an overview of the O3M SAF project background, currentstatus and future plans for the utilisation of the GOME-2 data. An importantfocus is the provision of summaries of the GOME-2 products including productprinciples and validation examples together with sample images. Furthermore,this paper collects references to the detailed product algorithm andvalidation papers.
