Variables:

site (str or None) – The site code extracted from the filename.
datastream_class (str) – The datastream class extracted from the filename.
facility (str or None) – The datastream facility code extracted from the filename.
level (str or None) – The datastream level code extracted from the filename.
datastream (str or None) – The datastram extracted from the filename.
date (str or None) – The date extracted from the filename.
time (str or None) – The time extracted from the filename.
ext (str or None) – The file extension extracted from the filename.

Example

>>> from act.utils.data_utils import DatastreamParserARM
>>> file = 'sgpmetE13.b1.20190501.024254.nc'
>>> fn_obj = DatastreamParserARM(file)
>>> fn_obj.site
'sgp'
>>> fn_obj.datastream_class
'met'

Constructor that initializes datastream data member and runs parse_datastream class method. Also converts datastream name to lower case before parsing.

dsstr: The datastream or filename to parse

set_datastream(ds)

Method used to set or reset object by passing a new datastream name.
