filter_coverage: Filter stations based on "coverage" requirements.
Description
Filters available weather stations based on a specified required minimum
coverage (i.e., percent non-missing daily observations). Weather stations
with non-missing data for fewer days than specified by coverage will
be excluded from the county average.
Usage
filter_coverage(coverage_df, coverage = 0)
Arguments
coverage_df
A dataframe as returned by the meteo_coverage
function in the rnoaa package
coverage
A numeric value in the range of 0 to 1 that specifies
the desired percentage coverage for the weather variable (i.e., what
percent of each weather variable must be non-missing to include data from
a monitor when calculating daily values averaged across monitors).
Value
A dataframe with stations that meet the specified coverage
requirements for weather variables included in the coverage_df
dataframe passed to the function.
