Function to screen dissolved oxygen data within the Everglades Ecosystem prior to evaluating compliance with established water quality standards.

Description

Function to screen dissolved oxygen data within the Everglades Ecosystem prior to evaluating compliance with established water quality standards.

Usage

DO.Screening(
  DateTime,
  DO,
  Temp,
  data,
  hour.lims = c(6, 18),
  max.DO = 20,
  temp.lims = c(5, 20)
)

Arguments

DateTime	as.POSIXct date and time
DO	Dissolved Oxygen Concentration
Temp	Surface water temperature
data	data.frame() with DateTime (DateTime.EST), Dissolved Oxygen (concentration; DO) and Temperature (Temp) data.
hour.lims	min and max hour to capture "day-time" DO
max.DO	Limit to the maximum observed DO for the system
temp.lims	limits to water temperature data that seem reasonable based on period of record.
...	specify other parameters as needed (min.hour,max.hour,max.DO,min.Temp,max.Temp)

Value

DO.Screening() assumes the data has a "DateTime.EST" field (date and time stamp), "DO" Field and "Temp" field to determine suitable data. Returns a "UseData" response.

Examples

## Not run: 
# data=data.frame(DateTime.EST=as.POSIXct(c("2015-05-01 08:00","2015-10-15 12:00","2015-10-15 5:00")),DO=c(15,2,3),Temp=c(18,27,3))
# data$UseData=DO.Screening(DateTime.EST,DO,Temp,data)
# data

## End(Not run)
