NAME

Weather::GHCN::App::StationCounts - Count stations in Weather::GHCN::Fetch station output

VERSION

version v0.0.011

SYNOPSIS

use Weather::GHCN::App::StationCounts;

Weather::GHCN::App::StationCounts->run( \@ARGV );

See ghcn_station_counts -help for details.

SUBROUTINES

run ($progname, $argv_aref)

Encapsulates the mainline logic so this module can be used in a test script. An application script merely needs to use this module and then call:

Weather::GHCN::App::StationCounts->run( \@ARGV );

See ghcn_station_counts -help for details.

read_data( $fh, \%count )

From the file handle $fh, read a list of stations in the format generated by Fetch.pm, and count the stations that were active in any given year.

parse_active_range ($stnid, $active)

Sometime the active range in data retreived from the NOAA station inventory is malformed. This routine tries to spot these malformed ranges and fix them.

get_options ( \@argv )

get_options encapsulates everything we need to process command line options, or to set options when invoking this script from a test script.

Normally it's called by passing a reference to @ARGV; from a test script you'd set up a local array variable to specify the options.

By convention, you should set up a file-scoped lexical variable named $Opt and set it in the mainline using the return value from this function. Then all options can be accessed used $Opt->option notation.
