Session 8: Aerosols, Processing and Visualisation
Processing Tools - AAPP - Nigel Atkinson, NWPSAF/MetOffice, UK
The ATOVS and AVHRR Pre-processing Package (AAPP) is a tool to process sounder and imager data from the NOAA, Metop and FengYun polar orbiting satellites. It was originally developed in the late 1990s to support processing of direct broadcast data from the NOAA-POES satellites, and has since been extended to accommodate Metop (including IASI) and more recently Suomi-NPP. The package is maintained by the EUMETSAT Satellite Application Facility for Numerical Weather Prediction (NWP SAF). An overview will be given of the capabilities of AAPP, including how it complements other processing packages such as IMAPP and CSPP. AAPP products include calibrated, re-mapped radiances (for NWP) and derived products such as cloud mask. Examples of the products and their uses will be shown.

Aerosol information from the O3MSAF - Piet Stammes, O3MSAF/KNMI, Netherlands
Aerosols are small liquid or solid particles in the atmosphere, like soil dust, sulphate and nitrate droplets, organic compounds, volcanic ash, etc.. Aerosols affect weather and climate by reflection and absorption of sunlight, by affecting cloud formation and precipitation, and by reducing visibility. Satellite detection of aerosols is often difficult because of the relatively weak reflectance of aerosols as compared to clouds and the background reflection of the underlying surface. Using UV-Visible spectrometers like OMI and GOME-2, UV absorbing aerosols like biomass burning smoke, volcanic ash and desert dust can be detected, even in cloudy cases and over land surfaces. In this presentation the current and future aerosol products from GOME-2 available from the O3MSAF will be introduced.

Website Tour - EUMETSAT page, NOAA pages ..., Nuno Moreira, IPMA, Portugal
In this session you will be taken on a website tour, visiting pages where polar satellite products referred during the whole EUMETRAIN Polar Satellite Week can be visualized. “Web-Visits” will naturally include EUMETSAT or NOAA pages and it will be an opportunity to make a wrap-up on the contents previously discussed...
