Get attainment categories

Description

Get attainment categories for each year and bay segment using chlorophyll and secchi depth

Usage

anlz_attainpep(meddat, magdurout = FALSE, trgs = NULL)

Arguments

meddat

result returned from anlz_medpep
magdurout

logical indicating if the separate magnitude and duration estimates are returned
trgs

optional data.frame for annual bay segment water quality targets, defaults to peptargets

Value

A data.frame for each year and bay segment showing the attainment category

Examples

meddat <- anlz_medpep(rawdat)
anlz_attainpep(meddat)

Analyze daily DO values relative to threshold

Description

Analyze daily DO values relative to threshold

Usage

anlz_dodlypep(dodat, thr = 3, impute = TRUE)

Arguments

dodat

result returned from read_pepdo
thr

numeric indicating appropriate dissolved oxygen thresholds, usually 3 mg/L for acute, 4.8 mg/L for chronic
impute

logical indicating of missing dissolved oxygen values are imputed with the year, month, site average

Details

The dodat data object can be used as input without downloading USGS data

If impute = TRUE, missing dissolved oxygen values in the complete daily time series are imputed to the average for the year, month, site combination. This is often necessary to create summary values that make sense. For example, if a month has incomplete data, the maximum below_cumsum value will not show 30 or 31 days even if every day in the observed record is below the threshold.

Value

data.frame

Examples

data(dodat)
dat <- anlz_dodlypep(dodat)
dat

Analyze monthly DO values relative to threshold

Description

Analyze monthly DO values relative to threshold

Usage

anlz_domopep(dodat, thr = 3, impute = TRUE)

Arguments

dodat

result returned from read_pepdo
thr

numeric indicating appropriate dissolved oxygen thresholds, usually 3 mg/L for acute, 4.8 mg/L for chronic
impute

logical indicating of missing dissolved oxygen values are imputed with the year, month, site average

Details

The dodat data object can be used as input without downloading USGS data

The date are summarized as three different values, where do_mgl is the average of all daily DO averages across the month, below_ave is the proportion of days in a month when concentrations in a given day fell below the threshold (1 would mean all days had an instance of DO below the threshold, 0 would mean none), and below_maxrun is the maximum number of sequential days in a month when concentrations in a given day fell below the threshold (30 or 31, depending on month, would indicate all days in a month had an instance of DO below the threshold).

If impute = TRUE, missing dissolved oxygen values in the complete daily time series are imputed to the average for the year, month, site combination. This is often necessary to create summary values that make sense. For example, if a month has incomplete data, the below_ave summary may indicate a value of one if all daily averages in the available data are below the threshold, whereas the below_maxrun summary may indicate a maximum run of days not equal to the number of days in the month.

Value

data.frame

Examples

data(dodat)
dat <- anlz_domopep(dodat)
dat

Count beach exceedances for enterococcus

Description

Count beach exceedances for enterococcus

Usage

anlz_entpep(entdat, thr = 104)

Arguments

entdat

result returned from read_pepent
thr

numeric value defining threshold for exceedance

Details

The exceedance threshold is set by default as 104 cfu/100 ml criterion. This is simply based on counts in a year when any value at any station was above the threshold for each 24 hour period in the record.

The samples column shows how many days of the year were sampled at each beach and the exceedances column shows how many samples were above the threshold.

Value

A data.frame with counts of exceedances per year for each beach

Examples

anlz_entpep(entdat)
