The ERS-2/GOME instrument and the package of atmospheric instruments under development for the Envisat-1 satellite will provide an unprecedented capability to study and monitor the Earth's atmosphere and its chemical constituents.

With a view to operational use by meteorological and environmental users, the instrument derived geophysical information as aerosol parameters is to be put in the form of a global map. In order to achieve this, the measurements taken by the instrument over limited areas and at different times need to be suitably integrated into a 3-D product by means of physical models.

The DAMS2P project aimed at prototyping a service-oriented product of this kind by initially using data from non-ESA missions (e.g. SAGE) and later aerosol GOME products derived from ERS-2.

The primary objective of the DAMS2P project was the mapping of aerosol extinction data, including the matching of data taken at different wavelengths.

The next steps consisted of:

• mapping aerosol properties derived from the spectral data;
• mapping additional atmospheric chemical species (H2O, HNO3).
