Olympic.NH4.df:
Ammonium Concentration in Precipitation Measured at Olympic National Park Hoh Ranger Station
Description
Ammonium (NH$_4$) concentration (mg/L) in precipitation measured at
Olympic National Park, Hoh Ranger Station (WA14), weekly or every other week
from January 6, 2009 through December 20, 2011.
Format
A data frame with 102 observations on the following 6 variables.
Date.On
- Start of collection period.
Date on which the sample bucket was installed on the collector.
Date.Off
- End of collection period.
Date on which the sample bucket was removed from the collector.
Week
- a numeric vector indicating the cumulative week number
starting from January 1, 2009.
NH4.Orig.mg.per.L
- a character vector of the original NH$_4$
concentrations reported either as the observed value or less than some
detection limit. For values reported as less than a detection limit,
the value reported is the actual limit of detection or, in the case of a
diluted sample, the product of the detection limit value and the
dilution factor.
NH4.mg.per.L
- a numeric vector of NH$_4$ concentrations with
non-detects coded to their detection limit.
Censored
- a logical vector indicating which observations are censored.
