File: /outgoing/iris_patches/8.04/README804

This is a summary of the IRIS 8.04 patches available on the SIGMET
ftp site.  File last updated 19 Feb 2004.  The general proceedure
for installing patches is:
 1) Move the file platform/foo.v1.gz to your IRIS_BIN directory.
 2) Rename the file it will replace (e.g. "mv foo foo.v0" )
 3) Uncompress the new file (e.g "gunzip foo.v1.gz")
 4) Make a symbolic link from the original name to the patch.
    (e.g. "ln -s foo.v1 foo"
 5) Set ownership and mode to exactly match the old file.  You can
    see this information with "ls -l foo*".
    (e.g. "chown operator foo.v1", "chgrp users foo.v1", "chmod 775 foo.v1")

UfToIris.v10.gz
UfToIris.conf.v10

Numerous changes to allow reading unusual UF input files.  This
pipe can be installed on older IRIS systems.  For HP-UX, you must
be running 11.11 or later.  We now support:

* Skipping some of the sweeps in the file.  This allows reading
data which does not start with sweep 1, as well as data which has
different data types on different sweeps, as well as data which
changes PRT on different sweeps.

* Overriding the wavelength in the file.  This allows reading
data which has inconsistent wavelengths in the file.

* Data in which the fixed angle changes during a sweep.

* Custom data types.  That is you can specify arbitrary 2-character
UF data strings and the IRIS data type they map to.  The mapping
can have a scale and offset, if desired.

* Ignoring specific data types.  You can block individual data types
which might otherwise cause problems.  For example if the PRT varies
for each sweep for velocity only.

* Multiple channels with different configuration.  This is required
if you have 2 sources of UF data, and one requires special configuration.
An example of this is WSR-88D data from the RSL 1.31 which requires
the wavelength override.  This feature is only available on IRIS
version 7.31 and later.

* Support for mixed bin spacing data.  The WSR-88D typically outputs
reflectivity at 1km, and velocity at 250 meters.

* Ignoring a few rays with missing required data.  For example, the
RSL 1.31 library produces data with velocity missing from the last
ray of the first sweep.
