Metar

---------------------------

Python-metar v1.5 includes updated documentation and a few minor bug fixes.
The old sourceforge site is no longer being updated, and so the only authoritative
source repository is the GitHub repo. To clone the project from there, use

git clone https://github.com/python-metar/python-metar.git

---------------------------
Python-metar v1.4 incorporates a handful of bug fixes and enhancements
made over the last couple of years. Notably, Toby White contributed code to
let the parser recognize and ignore trend forecasts and runway-state groups.

Starting with this release, new releases will be made available through my
sourceforge project, at http://python-metar.sourceforge.net/. I've also
converted my code repository from CVS to Git, and made public copies of the
Git repository available on Sourceforge and on Github. To clone the
repository, you can use either

git clone git://python-metar.git.sourceforge.net/gitroot/python-metar
or
git clone git://github.com/tomp/python-metar.git


- Merged Toby White's changes for parsing (and ignoring) runway state groups
and trend forecasts. (Thanks!)

- Report the peak wind and wind shift times, if included in the remarks.
(Requested by Daryl Herzmann.)

- Changed the date-handling code to avoid automatic month/year adjustment
if the month or year are specified explicitly.
(Thanks to Scott McKuen for reporting this.)

- Only allow single-digit numerator in fractional visibility values, to avoid
confusion with following temp/dewpt group.
(Reported by Franco Fiorese, Francesco Spada, and David Gregory.)

- Fixed the misuse of str() function and string() methods in a couple of spots.
(Reported by David Gregory and others.)

- Added tests for the visibility, trend, and runway state parsers.

- Added tests to verify that automatic month/year adjustment of the observation
date were being done correctly.

- Updated links to METAR resources in the README

---------

- The datatype classes now have __str__ methods, so you can user the
generic str() function to get their string representation.

- 'MMM' is now accepted to represent missing data in the wind group.

- Fixed bugs in the handling of wind observations reported in KMH and MPH.
(Thanks to Erik Bryer for reporting the MPH problem.)

- '/' placeholders for missing data in the weather group are handled better now.

- Added tests for KMH and MPH conversions to the test_speed.py script.

- Added tests for wind-group parsing to the test_metar.py script.

- Accept "11/2" as equivalent to "1 1/2" in the visibility group.

- Fixed a bug that prevented the error handler in get_report.py from reporting
the error message :-) (Thanks to Erik Bryer for reporting this.)

---------

- Save the 1-, 3-, 6- and 24-hr preciptation values as Metar attributes.

- Save the 6- and 24-hour max and min temperatures as Metar attributes.

- Save the peak wind speed and direction as Metar attributes.

- Save the sea-level pressure as a Metar attribute. The sea-level
pressure is treated as the station pressure, as well, if no station
pressure is otherwise reported.

- Added a peak_wind() method, to report peak wind data.

- 'QNH' and 'SLP' pressure groups are now accepted. 'INS' at the end of
a pressure group is recognized, as well.

- A group of four digits is accepted as a pressure group, now.

- Present-weather and cloud-cover lines are only written in the textual
output if observations of those phenomena were reported.

- The character 'O' is treated as a zero in the cloud-height, visibility
and wind fields.

- 'CORR' (in the modification field) is interpretted as 'COR'

- 'NIL' and 'FINO' (in the modification field) are interpretted as 'NO DATA'

- 'K', 'T' and 'LT' are all interpretted as 'KT'.

- 'SCK' is interpretted as 'SKC'

- 'MM' is now accepted as a placeholder in the 'temp' and 'dewpoint' groups.

- An 'integrity' field ('+' or-) has been created.

- 'RVRNO' groups are ignored, now.

- '0VC' is treated as 'OVC'.

- A pressure group consisting of just four digits with no leading 'A' or
'Q' is accepted now. The units are assumed to be inches if the value
is greater than 2500.

- An 'O' in a cloud height field is treated as a '0'.

- Modified to handle "MIFZFG".

- Moved regexp matching out of the _parse* methods and into the `__init__`
method. This lets me avoid unnecessary method calls and removes a bunch
of previously duplicated code. It gives a 10-15% speedup. The ability to
ignore trend groups has been temporarily lost as a result of this change.

- The date parsing code will assume we're in the previous month if the day
is greater than today's date.

- Rearranged the VISIBILITY_RE regexp to fix a parsing bug, which had
caused "1 1/2SM" to be parsed as two groups.

- Modified SKY_RE regexp to accept two to four digits in the cloud height,
and to treat 'O' as '0', if found in the height.

- Fixed a bug (a typo) in the vertical visibility handling code. This was
reported by Joseph Sheedy.

- Fixed a bug in reporting maximum visibility when there was no direction
for the maximum visibility.

- Changed the way the visibility group was parsed to allow better
handling of units. '9999U' and '7000M' are now accepted.

- Added support for sky group of the form '///030///', indicating cloud
height without coverage or type info.

- Support "KTS" as an alternative to "KT".
- Support "XX" as a placeholder for a missing temperature or dewpoint.
(These are violations of the spec, but are sometimes used, anyway.)
