DESCRIPTION

Get information from METAR that isn't explicitly in the METAR.

SUBROUTINES/METHODS

Methods that return a measurement return that as a Class::Measure::Scientific::FX_992vb object so the value can be converted to other units, like from feet to meters or from miles to kilometers.

Geo::METAR::Deduced->new()

Constructs a new Geo::METAR::Deduced object.

$m->metar()

Gets or sets the METAR string.

$m->mode()

Returns the METAR mode.

$m->date()

Returns the day of the month of the METAR. It doesn't return a date object because we don't want to make the implied month and year explicit.

$m->time()

Returns the time of the METAR as string. It doesn't return a date object because we don't want to make the implied month and year explicit.

$m->ceiling()

Returns the ceiling based on cloud level or vertical visibility data as measurement.

$m->visibility()

Returns the visibility as measurement.

$m->flight_rule()

Returns the flight rule based on ceiling and visibility as 0 for low IFR, 1 for IFR, 2 for marginal VFR and 3 for VFR.

$m->alt()

Returns the altimeter setting as pressure measurement.

$m->pressure()

Returns the pressure as measurement.

$m->dew()

Returns the dew temperature as measurement.

$m->temp()

Returns the temperature as measurement.

$m->wind_dir()

Returns the wind direction as angle measurement.

$m->wind_dir_eng()

Returns the wind direction in English, like Northwest.

$m->wind_dir_abb()

Returns the wind direction abbreviation in English, like NW.

$m->wind_speed()

Returns the wind speed as speed measurement.

$m->wind_gust()

Returns the wind gust speed as speed measurement.

$m->wind_var()

Returns if the wind is varying.

$m->wind_high()

Returns the highest direction of the varying wind as angle measurement.

$m->wind_low()

Returns the lowest direction of the varying wind as angle measurement.

Weather types

The following weather types return 0 when they are not observed, 1 when in a light condition, 2 for a normal condition and 3 for heavy:

$m->snow()
$m->dust()
$m->rain()
$m->ice_crystals()
$m->ice_pellets()
$m->drizzle()
$m->funnel_cloud()
$m->hail()
$m->squalls()
$m->partial()
$m->patches()
$m->dust_storm()
$m->small_hail_snow_pellets()
$m->volcanic_ash()
$m->freezing()
$m->fog()
$m->spray()
$m->mist()
$m->fog_banks()
$m->shallow()
$m->sand()
$m->sand_storm()
$m->smoke()
$m->haze()
$m->shower()
$m->dust_sand_whirls()
$m->thunderstorm()
$m->snow_grains()
$m->blowing()
$m->unknown_precip()

CONFIGURATION AND ENVIRONMENT

None.

DEPENDENCIES

INCOMPATIBILITIES

This module has the same limitations as Geo::METAR. We suspect there is also an incompatibility with a threaded version of perl 5.22.1.

DIAGNOSTICS

This module uses Log::Log4perl for logging.

BUGS AND LIMITATIONS

There is still plenty to deduce from the format that METAR has to offer in it's fullest form.

Please report any bugs or feature requests at Bitbucket .
