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