Calculate Surface Area, Volume, Mass of particle by particle number concentration.

Usage

nsvp(df, dlogdp = FALSE, dsty = 1)

Arguments

df

dataframe of particle size data: the first column of input is datetime; the other columns are number concentration (N, unit: #/cm3) or log number concentration (dN/dlogdp, unit: #/cm3) for each particle size channel. Column names of the other columns are the middle particle size for each particle size channel.

dlogdp

logical value, TRUE if the third column is log number concentration (dN/dlogdp).

dsty

numeric value, density of particle namtter.

Value

a list with 2 dataframe. The first dataframe is a time series for Surface Area (unit: µm2/cm3), Volume (unit: µm3/cm3), Mass (unit: µg/m3) of each channels; the second dataframe is a time series for total Surface Area, Volume, Mass of all channels.
