运行ASCII2NC
==========================

1. 将txt格式的站点资料转化为NetCDF格式

    数据必须转化为要求的格式：

        1. Message_Type
        #. Station_ID
        #. Valid_Time in YYYYMMDD_HHMMSS format
        #. Lat in degrees North
        #. Lon in degrees East
        #. Elevation in meters above sea level
        #. Grib_Code as the integer GRIB code value or variable name corresponding to this observation type
        #. Level as the pressure level in hPa or accumulation interval in hours
        #. Height in meters above sea level or above ground level
        #. QC_String corresponding to the quality control value (new format)
        #. Observation_Value in the units prescribed for the grib code

    例如：降水观测 (老的格式，缺质控栏）

    .. literalinclude:: examples/rnwst.ascii.2019052700_acc24
        :linenos:


    例如：能见度观测

    .. literalinclude:: examples/2020050200.vis
        :linenos:
