wmowwConversion
(file)[source]¶ Helper class to convert observed weather types into the classes 0/4/5/6/7/8/9 as used by Wetterturnier.de. Reads the wmo ww config file using
ConfigParser.ConfigParser
. The file contains the conversion rules from received observations to one of the main weather types (0,4,5,6,7,8,9). Can be used for present weather (ww) and past weather (w1/w2).Parameters: file ( str
) – String, file name containing the specifications.-
convert
(section, code)[source]¶ Convert an observed weather code into the new one. “section” defines the conversion table. If set to “past” (or “w1” or “w2”; not case sensitive) the [past weather] conversion table will be used. If set to “present” (or “ww”) the [present weather] will be used. Returns the value in which the observed “code” is converted. If no specificiation is available a “None” is returned.
Parameters: - section (
str
) – One of past/w1/w2 or present/ww. Not case sensitive. - code (
int
) – Integer with the observed code. If None is given, None will be returned. Same yields if “code” is no integer (None returned).
Returns: Returns an integer or None, depending on the settings.
Return type: int/None

# - DESCRIPTION: Conversion table for repored weather types, from
# WMO 94 BUFR CODE TABLE. Extracted from
# BUFRCREX_29_0_0_CodeFlag_en.txt (downloaded Jan 2018
# from http://www.wmo.int/pages/prog/www/WMOCodes/WMO306_vI2/LatestVERSION/LatestVERSION.html)
#
# FORMAT: the left hand side of the setting can
# be whatever you like, except that on "=" can be
# in the description. The right hand side has to be
# of the format "<integer> gets <integer>" or
# "<integer> gets <None>". Everything else will be
# ignored.
# The right hand side means nothing else than:
# If BUFR message is "10" it gets a "0" in synop
# weather type representation. Or whatever you define.
#
# PLEASE NOTE: if a flag is defined more than once
# only the last will be used which might get confusing.
# Take care to make unique definitions!
