Most indicators are calculated from mass concentrations. This functions converts all volume concentrations to mass concentration with the exception of NOx. The argument keep_ppb allows to keep the volume concentrations

Usage

calculate_mass_concentrations(data, keep_ppb = FALSE)

Arguments

data

input data in rolf format

keep_ppb

usually volume concentrations are not used for analyses and are dropped with the exception of NOx. When FALSE drops parameters with ppb/ppm units except NOx. Default FALSE

Value

tibble in rolf format containing mass concentrations
