•The goal of the PAMS network is to help assess ozone
control programs by
–identifying key
constituents
and parameters;
–tracking trends;
–characterizing
transport;
–assisting in
forecasting
episodes; and
–assisting in improving
emission
inventories.
•Toxic VOCs sampled by
the PAMS network include
benzene, formaldehyde,
xylenes, toluene,
ethylbenzene, styrene, and acetaldehyde.
•PAMS sites make subdaily measurements at the same sites
that are useful in assessing
diurnal trends.
