2. Purpose
----------
OPS-LRS processes MetOp IASI data from Level 0 to Level 1c.

This version incorporates the latest OPS release from CNES, with NWP-SAF
modifications.

The package has been tested with post-launch IASI data.


3. Installation
---------------
Please follow the instructions in the OPS-LRS User Manual.

Note that before running OPS-LRS with live IASI data you should download the
latest configuration files from EUMETSAT:
ftp://ftp.eumetsat.int/pub/OPS/out/user/IASI/IASI_aux_db


4. License
----------
To use this software, users need to have registered for OPS-LRS with the
NWP SAF (www.nwpsaf.org), and to have agreed to the terms of the OPS-LRS 
license agreement.


5. Delivery mechanism
---------------------
OPS-LRS is delivered by FTP or CD-ROM. The test case may not be permanently
available on the FTP site; if you require it please contact the NWP SAF
Helpdesk.


6. System requirements
----------------------
Supported platforms include: AIX, IRIX, Solaris and Linux PC. HPUX is not
supported.

The host machine must be able to run multithreaded applications, using pthreads
(POSIX threads).

To build OPS-LRS requires a Fortran 90 or FORTRAN 77 compiler, a C compiler and
a C++ compiler.

To run OPS-LRS requires about 1 Gbyte of disk space and 2 Gbyte of memory.

Standard Unix utilities (including make, ar, tar, perl5, lex, yacc) are used.


7. Unpacking the files
----------------------
Apart from the release note and User Manual, all other files are packaged as
gzipped tar files. To unpack, bring up a Unix terminal window, copy the tgz
file to a suitable location on your file system and enter the command:

  tar -xzf xxx.tgz            where xxx is the name of the component
  
or if your system does not support the "-z" option in tar,

  gunzip -c xxx.tgz | tar -xf -
  

8. Documentation
----------------
The main user document is the OPS-LRS User Manual (NWPSAF-MF-UD-006). This
contains instructions on installing OPS-LRS and running the supplied test case.
The document may be viewed using Adobe Acrobat Reader.

The reference documents in ops-lrs-doc.tgz are supplied for information only and
the NWP-SAF does not take any responsibility for the accuracy or readability of
the documents. There is an index file "ops-lrs-docs.txt" giving the file names, 
titles and version numbers of the reference documents.
