  3. GMV Aerospace and Defence GlobAEROSOL Project Overview

  4. What is GlobAEROSOL? • Globaerosol is a consortium of: • GMV- Spain. • Project lead and processor implementation • RAL (Rutherford Appleton Laboratory). UK • Developing SEVIRI algorithm & validation • Oxford University- UK • ATSR-2 & AATSR algorithm & validation • Yves Des-Champs as MERIS Consultant

  5. What is GlobAEROSOL? • MERIS product is the standard ESA level 2 aerosol retrieval • Retrieves optical depth at 865nm • ATSR-2, AATSR and SEVIRI products are produced using the Oxford-RAL Aerosol and Cloud (ORAC) retrieval scheme: • Optimal estimation retrieval scheme • Retrieves 550 nm optical depth, effective radius and surface albedo for a set of predefined aerosol components. Other GlobAEROSOL parameters derived from these.

  6. What is GlobAEROSOL? • The forward model uses the DISORT radiative transfer model in conjunction with a set of aerosol models based on a subset of the same aerosol classes used in the MERIS retrieval. • MARITIME, URBAN, BIOMASS, CONTINENTAL and DESERT DUST • The aerosol retrieval makes use of the visible channels only: • ATSR-2: 0.67, 0.87, 1.6 μm • AATSR: 0.55, 0.67, 0.87, 1.6 μm • SEVIRI: 0.64, 0.81, 1.6 μm • To provide an estimated speciation, the retrieval is repeated for each aerosol class and the model which best matches the measurement is selected

  7. What is GlobAEROSOL? • GlobAEROSOL is not a single product, but a range of products that all have a common format and are all on the same spatial grid • “Orbit” files, which contain all the retrieval output, are available for each individual instrument • “Daily” files, which contain speciated, quality controlled products for a given day, are available for each instrument individually and in a merged product, in which all retrievals are combined. • Monthly composites for each instrument and the merged product are also produced on a 1x1° lat/lon grid All orbit and daily products on a 10km sinusoidal grid

  8. What is GlobAEROSOL? • MERGED product • Product weighted according to a hierarchy of instruments, associated error (if available) and time

  9. Status of the processing • 13 years Dataset produced by GlobAEROSOL Team • The following data is available: • ATSR-2: 1995 – 2003 • AATSR: 2002 – 2007 • SEVIRI: 2004 – 2007 • MERIS: 2002 – Mid 2005 • The remaining work is being dispatched this month: • MERIS: Mid 2005 – 2007 Last Data Arrived in August. • End of Processing by mid September (including all statistical and merged products).
