Data
Analysis
Process
1.
Chemical
composition
data
from
urban
sites
(
from
the
EPA
Speciation
Network,
or
ESpN)
and
regional
sites
(
from
the
IMPROVE
visibility
monitoring
network)
were
analyzed
for
the
12
months
extending
from
April
2002
to
March
2003.
Complete
sites
were
chosen
if
they
had
11
complete
observations
per
quarter
for
all
major
PM2.5
species
for
all
4
quarters
of
interest.
The
worksheet
'
Map
1'
displays
the
locations
of
urban
and
regional
monitors
that
met
the
2.
For
every
complete
urban
ESpN
site,
the
nearest
IMPROVE
site
was
identified
using
a
geographic
information
system.
Note
that
in
some
cases,
the
same
IMPROVE
site
is
used
as
the
"
regional
site"
for
more
than
one
of
the
urban
locations.
Sipsey,
Shining
Rock,
Cohutta,
Brigantine,
Quaker
City,
Livonia,
and
Arendtville
are
IMPROVE
sites
that
are
used
more
than
once
to
represent
regional
concentrations
for
metro
areas
in
the
eastern
U.
S.
The
worksheet
'
Map
2'
shows
the
137
urban
sites
and
the
IMPROVE
sites
paired
with
them.
These
site
pairings
were
then
used
to
estimate
urban
excess
percentages
by
PM2.5
component.
3.
Only
data
for
site
pairs
associated
with
metro
areas
having
a
violating
monitor
are
included
in
this
PM2.5
designations
worksheet.
If
a
metro
area
did
not
have
an
urban
speciation
site
with
complete
data,
then
PM2.5
urban
excess
percentages
from
the
closest
urban­
regional
site
pair
were
used
as
a
surrogate
for
the
area.
Some
violating
metro
areas
had
more
than
one
complete
urban
ESpN
site;
in
those
situations,
the
urban
ESpN
site
with
the
highest
gravimetric
mass
was
used
to
calculate
the
weighted
emissions
scores.

Ammonium
sulfate
(
a.
k.
a.
'
sulfates')
is
calculated
as
4.125
*
sulfur.
Ammonium
nitrate
(
a.
k.
a.
'
nitrates')
is
calculated
as
1.29
*
nitrate.
TCM
is
equal
to
elemental
carbon
+
(
1.4
*
organic
carbon).
Crustal
mass
is
calculated
according
to
the
methodology
used
in
the
IMPROVE
program.
All
data
have
been
corrected
for
elevation.

5.
For
each
PM2.5
component,
the
urban
increment
mass
is
estimated
by
subtracting
the
regional
mass
from
the
urban
mass.
The
sum
of
these
four
components
is
the
total
urban
increment
mass.
(
In
cases
where
regional
mass
for
a
component
exceeds
the
urban
mass,
the
urban
increment
mass
for
that
component
was
assumed
to
be
zero.)
The
percentage
that
each
PM2.5
component
comprises
of
the
total
urban
increment
mass
was
then
calculated.
These
component
percentages
were
used
in
calculating
the
weighted
emissions
scores
in
the
spreadsheet
"

areas
with
