1. Package contents
-------------------
The following files are included in this release (with file sizes in bytes):

  RELEASE_NOTE_OPS-LRS_V4-2.txt             4195 This release note
  OPS_V4-2-AAPP-sl-20090324_update.tgz    250694 IASI OPS-LRS incremental update

This is an incremental update; users need to have already installed
OPS-LRS_V4-0-p123, issued on 07/10/2008.

The OPS-LRS package requires AAPP v6.4 or higher and the FFTW and XERCES
libraries that have been issued previously with OPS-LRS.

For functional testing, the test case iasi-test-dump-20070215.tgz (issued
previously) may be used.


2. Purpose
----------
OPS-LRS processes MetOp IASI data from Level 0 to Level 1c. This version
incorporates the latest OPS updates from CNES.

The Level 0 data are normally obtained by direct-readout AHRPT.


3. Installation
---------------
a. Copy the tgz file to your OPS-LRS top directory (containing directories src,
   config, etc.)

b. Unpack it using the command
   tar -xvmzf OPS_V4-2-AAPP-sl-20090324_update.tgz

   or if your system does not support the "-z" option in tar, use
   gunzip -c OPS_V4-2-AAPP-sl-20090324_update.tgz | tar -xmf -
   
c. Configure and build OPS-LRS following the instructions in the OPS-LRS User
   Manual. If you have already built version OPS-LRS_V4-0-p123 then it is
   sufficient to just type 
     make
     make install

Note that before running OPS-LRS with live IASI data you should download the
latest configuration files which are available from the EUMETSAT UMARF or from
the AAPP ftp site in directory OPS-LRS_aux.


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, Solaris and Linux PC. HPUX is not supported.
IRIX users should contact the NWP SAF Helpdesk for guidance.

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. Documentation
----------------
There are no changes to the User Manual or other documents.
