1.1 Why Choose AATSR Data?
The AATSR instrument is capable of
retrieving a variety of geophysical
measurements. In order to exploit these
effectively, it is necessary to understand
exactly what AATSR measures, why the instrument has
been designed to operate in this way and
how these measurements are made.
AATSR data also offer a number of unique capabilities
and advantages over data from similar
imaging instruments. These are also
covered in this User Guide.
The results of these features are data suitable for a
wide range of potential applications. A
summary of products and applications is
provided to assist the user in
identifying the most suitable product for his or her
Subsequent sections cover the following themes:
The ENVISAT Data Policy
The conditions of data distribution for ENVISAT data
are directly related to categories of
use, as defined by the ENVISAT Data
Policy (MMO-POL-0003-EOAD: ENVISAT Data
Policy, Issue 1 Revision 0, 23 August 2000).
- Category 1 use: Research and applications
development use in support of
the mission objectives, including
research on long-term issues of Earth
System science, research and
development in preparation for
future operational use, certification of
receiving stations as part
of the ESA functions, and ESA
- Category 2 use: All other uses that do not fall
into Category 1, including
operational and commercial use.
For Category 1 users, the Data Policy, applicable for
both ERS and ENVISAT, provides the
possibility to submit Category 1 use
proposals at any time beyond the fixed dates imposed
by specific Announcements of Opportunity.
How to Order AATSR Data
A number of interactive catalogues are available for
browsing ESA earth observation data.
These can be found at http://www.envisat.esa.int/services/.
For data distribution falling under Category 1 use,
the data will be provided by ESA at
reproduction cost or free of charge (to
be waived by the Earth Observation Program
Board). If you wish to submit a proposal for
Category 1 use of data please follow the
guidelines for proposal submittal at the
dedicated Earth Observation Principal Investigator
Portal at http://eopi.esa.int/esa/esa.
Category 1 users can receive ENVISAT data on media,
via FTP or via the web, depending on the
nature of the order. The ESA Earth
Observation Help Desk Team (EOHelp@esa.int) can
also advise on data access issues.
Should you wish to purchase ERS or ENVISAT data for
commercial or operational use (Category 2), please
contact either of the two distributing

Under the terms of the ENVISAT Data Policy, in their
capacity as AO Instrument Provider,
DEFRA have the right to make and
distribute copies of AATSR data for its own use, for
use by other funding entities of AATSR
and for research groups designated by
DEFRA. Users with links to Defra or the other
AATSR programme partners should consult their local
contacts within these agencies.
