.TH WMWEATHER 1.1 "19 January 1999"
|
|
.SH NAME
|
|
WMWEATHER \- Dockable Weather Monitor
|
|
.SH SYNOPSIS
|
|
.B wmWeather -station <4-char station ID> [-h] [-display <Display>] [-metric] [-kPa] [-hPa] [-mmHg] [-beaufort] [-mps] [-delay <Time in Minutes>] [-bc <color>] [-tc <color>] [-lc <color>] [-dc <color>] [-wgc <color>]
|
|
.SH DESCRIPTION
|
|
.PP
|
|
wmWeather monitors local weather conditions (temperature, Dew Point, Pressure,
|
|
Humidity and Wind direction and speed). The user needs to specify a
|
|
4-character `METAR station identifier code'. (The standardized METAR station
|
|
designations and current weather reports are designed for use by the aviation
|
|
community. Since most major cities have at least one airport, there is usually
|
|
one or more METAR stations in a given city.) You (obviously) need to be
|
|
connected to the internet and you also need to have wget installed (most linux
|
|
systems should have it already). wmWeather will then attempt to download the
|
|
latest METAR report for the station of your choice (from the National Weather
|
|
Sevice run by NOAA).
|
|
.PP
|
|
You can toggles back and forth between imperial and metric units. I.e. between
|
|
(degrees Fareheight, inches of Mercury, and miles per hour) and (degrees
|
|
Celsius, millimeters of Mercury, and kilometers per hour). Any key press will
|
|
do this.
|
|
.PP
|
|
Also, a left double click will bring up the fully decoded METAR report up in
|
|
xmessage. And a right double click will force an immediate update (i.e.
|
|
wmWeather will attempt to grab the weather information).
|
|
.PP
|
|
When the wind speed turns red, this means that the wind is gusty and the listed
|
|
value is an average only. Similarly, a red direction indicates a variable wind
|
|
direction and the value given is the average direction.
|
|
.PP
|
|
To find out more about the METAR/TAF system and to find the METAR code for your
|
|
location, look at http://www.nws.noaa.gov/oso/oso1/oso12/metar.htm for NOAA's
|
|
"National Weather Service METAR/TAF Information" page. To determine what your
|
|
station ID is use the lookup utility at:
|
|
http://www.nws.noaa.gov/oso/siteloc.shtml.

|
.SH OPTIONS
|
|
.TP
|
|
.B \-h
|
|
Display list of command-line options.
|
|
.TP
|
|
.B \-display <display>
|
|
Use an alternate X Display.
|
|
.TP
|
|
.B \-station <4-char station ID> (or \-s <4-char station ID>)
|
|
This option tells wmWeather which METAR station to show data for.
|
|
.TP
|
|
.B \-metric (or \-m)
|
|
Display temperatures in degrees Celsius.
|
|
.TP
|
|
.B \-kPa
|
|
When toggled to Celsius, display pressure in units of kPa.
|
|
.TP
|
|
.B \-hPa
|
|
When toggled to Celsius, display pressure in units of hPa (i.e. milliBars).
|
|
.TP
|
|
.B \-mmHg
|
|
When toggled to Celsius, display pressure in units of millimeters of Mercury. (This is
|
|
the default for Celsius when no other units are specified).
|
|
.TP
|
|
.B \-beaufort
|
|
When toggled to Celsius, display wind speeds on the "beaufort scale".
|
|
.TP
|
|
.B \-mps
|
|
When toggled to metric display, show windspeed in units of meters/second.
|
|
.TP
|
|
.B \-delay <Time in Minutes>
|
|
Override time (in minutes) between updates (default is 15 minutes). (Times are approximate.)
|
|
.TP
|
|
.B \-lc <color>
|
|
Set the color of the labels. (E.g. -lc red or -lc salmon or -lc #4523ff).
|
|
.TP
|
|
.B \-bc <color>
|
|
Set the background color. (#8e8e69 is LCD-ish).
|
|
.TP
|
|
.B \-dc <color>
|
|
Set the color of the data entries.
|
|
.TP
|
|
.B \-tc <color>
|
|
Set the color of the station ID/update time header.
|
|
.TP
|
|
.B \-wgc <color>
|
|
Set the gusty-wind/variable-direction color. The wind speed indicator will turn
|
|
this color when the wind speed is gusty. (The value shown in this case is the
|
|
average speed). Similarly, the wind direction indicator with change to this
|
|
color when the wind direction is variable. (The value shown in this case is the
|
|
average direction).
|
|
.SH BUGS
|
|
Let me know if/when you find any.
|
|
.SH NOTES
|
|
Requires that a (fairly recent) version of wget be installed on your machine.
