The config Module

This module contains classes and enums used to configure gridMET processing and specify its parameters

class DateFilter(value: str)[source]

Class, implementing filtering by dates. Primarily used for debugging and testing purposes to avoid long running calculations.

The condition can be specified in one of the following ways:

Range: YYYY-MM-DD:YYYY-MM-DD only dates falling in the given
range will be accepted. Example: ‘2009-12-30:2010-01-03’ means that only 5 days between the 30-th of December of 2009 and January 3, 2010 will be accepted
Day of Month: dayofmonth:DD, example: ‘dayofmonth:12’ means that
only dates corresponding to the 12-th of every month will be accepted
Month: month:MM only dates in the given month will be accepted
Month and day of a year: date:MM-DD, example: ‘date:03-14’ means
that only March 14 for each year will be accepted.
