2. This distribution of AAPP (Version 5.1) integrates the versions 4.0 to 4.5, 
and addresses the list of known bugs and problems on the AAPP webpage. 
However, some portability problems might still require manual adaptation 
during the intallation process. Details are given in the Installation Guide.

3. The changes for AAPP version 5, compared with version 4, are detailed in the
Product Specification (NWPSAF-MO-DS-006.pdf) and Top Level Design
(NWPSAF-MO-DS-007.pdf).

4. AAPP Version 5.1 contains all modules for the processing of TOVS and ATOVS 
data to level 1b, 1c and 1d, and for mapping AVHRR data onto the HIRS data grid. 
Both TOVS and ATOVS modules have been tested with space based data.  
Examples of HRPT data are included in the distribution, along with output
results to allow users to compare with their own test.

5. For AAPP V5, some additional documents have been added (compared with V4).
These are:
     - An appendix to the Scientific Description, providing more detailed
       information on navigation.
     - AAPP Version 5 Top Level Design document
     - AAPP Version 5 Product Specification
In addition, selected parts of the AAPP-5 Test Folder have been provided, to
allow the user to have access to detailed test results.

6. Before you start building AAPP version 5 it is recommended that you consult
the Installation Guide, which contains detailed instructions.

7. Any comments and proposals for improvements are welcome. Please use the
NWP-SAF feedback form, available from the AAPP web site at
http://nwpsaf.eu/web-test/deliverables/aapp/index.html



The CD-ROM contains this release note and the following directories:

Note:    Some types of CD-ROM burning software append a version number ";1" 
(and ".;1" if the file name has no suffix) at the end of each file name. This 
appendix is not visible on most systems. If you can see it on your system then
strip it off by renaming the files.

Note:    Most of the file names on the AAPP V5 CD-ROM have capital letters.
Nevertheless, on some systems, it may happen that you see the names with small 
letters. Take this into account when following the instructions of the 
installation guide where the files are referenced with capital letters.
