NAME

mc2area - A filter for converting McIDAS packetized data to regular files

SYNOPSIS

mc2area [-p path] output_filename

PARAMETERS

Command Line	Description
-p=path	Specifies the output path for data
output_filename	Specifies the name of the output file. The path is prepended to the filename

DESCRIPTION

This program acts as a filter for data being ingested by the LDM on the McIDAS data feed. The McIDAS feed includes satellite imagery and other products such as profiler data in netCDF format which WXP can use. The McIDAS data is sent to the LDM in a packets and the FILE action on the LDM will not remove the packet information. Thus, there is the need for a filter to strip this information out.

Since this is a filter, the input is from standard input. The command line specifies only the output files. For example:

mc2area -p /data/profiler 97042200.prf < data/raw/97042200.prf_raw

The program can also be used directly by the LDM:

MCIDAS  ^LWTOA3 14.
      PIPE  -close /usr/local/bin/mc2area -p /data/ldm/mcidas %y%m%d%H.sve

MCIDAS  ^LWFILE PROF
      PIPE  -close /usr/local/bin/mc2area -p /data/ldm/profiler %y%m%d%H.prf

The output of the program is the unpacketized data. For satellite images, this is the compressed AREA file which can be used by xsat. For the profiler data, this is the netCDF data file which can be used by prfplt.
