M ETEOROLOGICAL ANALYSIS

June 27, 2008

The added emissions from an unprecedented number of lightning

- generated

wildfires in northern and central California caused an exceedance of the 1

- hour

federal ozone standard at Folsom on June 23, 2008 (re fer to discussion of

Episode 1). Over the next several days, the wild fires continued to burn

. Although wildfire emissions continued to cause elevated ozone concentrations

during this time period, concentrations did not exceed the standard

, because

increa sed dispersion served to dilute the added emissions burden

. However, as

more stable conditions settled over the area

, the continuing wildfire emissions

that were transported into the Sacramento Valley, along with a substantial

amount of wildfire

- related o zone carried over from the previous day, resulted in

an exceedance of the 1

- hour standard at the Folsom site on June 27. Although

wildfire emissions can be layered throughout the atmosphere, this analysis

focuse s on emissions in the mixed layer because em issions in this layer impact

ground level ozone concentrations

. In this document t he mixed layer is

considered that portion of the lower atmosphere where temperature decreases

with height from the ground to the base of the lowest inversion layer.

Analy sis

H undreds of wildfires started by lightning strikes during the June 20

- 21 , 2008,

storm system continued to burn and grow in size

. By June 27, many of the fires

that ringed the Sacramento Valley were more than 300 acres in size, and a

substantial numbe r were more than 10,000 acres in size. Overall, nearly 200

fires, totaling tens of thousands of acres

, had burned i n and around the

Sacramento Valley (see Figure 1 and Table 1 ) , and e missions from the

numerous wildfires continued to drift into the Sacrame nto Valley , building up a nd

impact ing ambient ozone concentrations.

The Day b efore the Exceedance: Meteorological conditions on the day

preceding the June 27 exceedance were similar to those preceding the June 23

exceedance. As wildfires burned in the Coast Range Mountains, flow from the

northwest transported emissions from these fires to the San Francisco Bay Area

(Bay Area; see Figures 2 through 5 ). During the daylight hours on June 26, the

prevailing southwest surface winds carried these fire

- relat ed emissions from the

Bay Area into the southern Sacramento Valley (see Figures 6 and 7 ). The

mid

- day NASA satellite image shows a relatively thick layer of smoke from the

surrounding fires covering the northern portion of the Bay Area and southern

portio n of the Sacramento Valley ( refer to Figure 2 ).

The build

- up of smoke throughout the southern Sacramento Valley and its

presence at ground level is confirmed by airport visibility observations. Figures 3

### 2

through 5 show the reduction in visibility from ea rly morning to late afternoon.

During the early morning hours (0300

- 0400 PST), there was some reduction in

visibility in the Bay A rea (7 to 10 miles), with more substantial reductions in the

southern Sacramento Valley (4 to 6 miles). These were accompani ed by reports

of smoke and haze (refer to Figure 3 ). Later in the morning (0900

- 1000 PST),

wildfire emissions start ed to build

- up in the areas surrounding Folsom, and

visibilities in the foothills of the Sierra Nevada were as low as 1.5 miles (refer to

F igure 4 ). By 1500 PST, wildfire emissions had been transported and

concentrated in the southern Sacramento Valley (refer to Figure 5 ). Sites in the

Folsom area report ed visibilities in the range of 1.5 to 3 miles, and smoke was

observed in the air. Alth ough the wildfire impact did not cause an exceedance on

June 26, the associated wildfire

- generated pollutants and emissions persisted

into the next day, resulting in a very high level of ozone carryover at Folsom

.

The Day of the Exceedance: Several facto rs contributed to the June 27 ozone

exceedance at Folsom

. First, there was a very high level of ozone carried over

from the previous day. The low mixing height and eddy circulation pattern during

the early morning hours kept emissions carried over from t he previous day

trapped near the ground in the southern Sacramento Valley. Ozone

concentrations within this air mass were about one

- third the level of the federal

1

- hour standard and about three times higher than normal (see Figure 8) . This

high starting level was added to during the day of June 27.

Second, the wind direction was optimal for transporting additional emissions from

the fire areas to the southern Sacramento Valley. During the very early morning

hours of June 27, surface air movement in the southern Sacramento Valley was

controlled by the typical downslope drainage flow. Drainage flow from the

northeast carried emissions from wildfires burning in the Sierra Nevada

Mountains ( see Table 2). During this same time period, drainage flow from th e

west

- southwest carried emissions from fires burning in the Coast Range

Mountains (see Table 3). Emissions from both directions were transported into

the southern Sacramento Valley.

In addition to the drainage flow, there was sea breeze flow from the Bay Area

through the Carquinez Strait (see Figure 9 ). These light winds were driven by a

weak onshore pressure gradient . The pressure gradient is the difference in

atmospheric pressure between two areas

, and it provides a force which moves

air from highe r to lower pressure. At 0400 PST , the surface pressure difference

was 1.6 millibar s between San Francisco (KSFO ; higher pressure area) and

Sacramento ( KSAC ; lower pressure area) . The sea breeze winds decreased as

they reached the southern Sacramento Vall ey, setting up a localized eddy

circulation in the southwestern portion of the Valley. Emissions from wildfires

burn ing in the Coast Range Mountains were transported into the Bay Area ( see

Figures 1 0 through 1 4 ). The sea breeze then carried these fire

- re lated emissions

from the Bay Area into the southern Sacramento Valley. These emissions

, along

with drainage flow emissions

, were caught

- up in the localized eddy circulation

pattern during the overnight hours, trapping them in the southern portion of the

### 3

S acramento Valley ( refer to Figure 9 ). Furthermore, because the overnight

height of the mixed layer was low, the wildfire emissions were confined to a

relatively shallow layer and were concentrated near the surface ( see Figure 1 5 ).

The pressure gradient ( 4.9 millibars ) between Reno (KRNO; higher pressure

area) and Sacramento (KSAC; lower pressure area) at 0400 PST helped keep

emissions in the Valley

.

By late morning and into the afternoon, emissions from the various areas mixed

and spread throughout the S acramento Valley

. E missions from fires burning in

the Coast Range Mountains continued to be transported into the Bay Area (refer

to Figures 1 0 through 1 4 )

. These emissions in the Bay Area then continued to

drift into the southern portion of the Sacrament o Valley as the afternoon onshore

pressure gradient strengthened to 3.0 millibars between San Francisco (KSFO;

higher pressure area) and Sacramento (KSAC; lower pressure area)

, sustaining

the moderate onshore sea breeze ( refer to Figure s 1 6 and 1 7 ). This was

accompanied by a continuing eddy circulation pattern in the southwestern portion

of the Valley and a positive surface pressure gradient between Reno (KR NO ; higher pressure area) and Sacramento (KSAC; lower pressure area) , which

prevented emissions from being blown out of the Valley

. As s hown in the

satellite images ( see Figure s 1 3 and 1 4 ), smoke from fires in the adjacent

mountains shrouded the entire Sacramento Valley

. Later in the afternoon, as the

eddy circulation pattern weakened, some of the emis sions that had been trapped

in the eddy dispersed into the sea breeze flow within the southern Sacramento

Valley , adding to the emissions burden at Folsom.

Third

, the height of the mixed layer increased as the day progressed . This

allowed wildfire emis sions from a larger volume of air to be mixed down to the

surface, where they could impact ozone concentrations. Over the course of the

day, the height of the mixed layer, measured at Elk Grove, increased from

a pproximately 150 meters in the morning to mo re than 500 meters by 1500 PST

( refer to Figure 1 5 ). The increase in the height of the mixed layer allowed

additional wildfire emissions to reach the ground. These emissions combined

with those transported closer to the surface and compound ed the severit y of the

wildfire impact. As the height of the mixed layer increased over several hours

,

o zone concentrations also increas ed , reaching a maximum at 1500 PST

. Although the relatively low height of the mixed layer on June 27 helped to trap

wildfire emissio ns, the surrogate day assessment indicates conditions were not

sufficient to cause an exceedance under a normal emissions load (see Sonoma

Technology, Inc., Appendix Y).

Airport observations confirm the carryover of wildfire

- related emissions from t he

previous day, as well as the transport and build

- up of wildfire emissions

throughout the day on June 27 and their presence at ground level. During the

early morning hours of June 27 (0300

- 0400 PST), visibilities were low throughout

the northern portion of the Bay Area and the Sacramento Valley ( refer to

Figure 1 0 ). The low visibilities in the Folsom area , along with observations of

smoke

, confirm the high level of smoke carryover from the previous day. As time

### 4

progressed (0900

- 1000 PST) , visibilities were reduced even further (3 to 5 miles

in the northern Bay Area and 2.5 to 3 miles in the southern Sacramento Valley),

as additional wildfire emissions were added to the carryover burden ( refer to

Figure 1 1 ). During this time, there were widespread repor ts of smoke and haze.

As shown in Figure 1 2 , the greatest wild fire impact in the southern Sacramento

Valley occurred in the late afternoon, when visibility wa s only 2 to 2.5 miles at all

three sites in the Folsom area . In addition, these three sites, as well as other

surrounding sites, report ed smoke at ground level , indicating that wildfire

emissions reached the surface.

Fourth , ambient temperatures in the Sacramento area on June 27 were high

enough to promote ozone formation from wildfire emissions. The maximum

temperature at Folsom reached 99 degrees Fahrenheit . While this temperature

is not unusual for the Folsom area, the amounts of available precursor emissions

in the ground level air mass were unusual , and t he added emissions burden from

the wi ldfires was sufficient to push local ozone concentrations above the federal

1

- hour standard. A comparison of maximum temperatures in the Sacramento

region concluded that maximum temperatures on June 27 were similar to those

on the surrogate day, when ozon e concentrations were below the level of the

standard. Hence, wildfire emissions were a critical factor in the June 27

exceedance.

In conclusion, t he transport and build

- up of wildfire

- related emissions and their

substantial contribution to the June 27 1

- hour federal ozone exceedance at the

Folsom monitoring site is supported by several factors, as summarized, below:

1) Wildfire emissions from the previous day resulted in a very high level of

wildfire

- related ozone carryover. The level of carryover was abou t

one

- third the level of the 1

- hour standard, and it was nearly three times

higher than what is typical for the Folsom site.

2) Overnight surface drainage winds transported additional wildfire emissions

from both the Coast Range and Sierra Nevada mountains into the

southern Sacramento Valley. These emissions were caught up in a

localized eddy circulation pattern and added to the emissions burden on

the June 27 exceedance day.

3) Daytime s urface winds from the southwest occurred in combination with

very low visibilities and observations of smoke in the northern Bay Area

and southern Sacramento Valley. This combination of conditions and

observations indicate a continuing increase in wildfire

- related emissions

from fires burning in the surrounding mountains

.

4) The morning onshore pressure gradient, along with the local eddy

circulation pattern, trapped emissions in the southern Sacramento Valley.

Additionally, the pressure gradient between Reno and Sacramento helped

keep emissions from moving out of the Vall ey.

### 5

5) The inversion present on June 27 trap p ed wildfire emissions close to the

ground

. However, based on the surrogate day assessment, the inversion

was not sufficient or typical of the conditions associated with an

exceedance under a normal emissions load.

6) Although the maximum June 27 t emperature at Folsom was high

, maximum temperatures in the Sacramento region were not high enough to

generate an ozone exceedance based on a normal emissions load, as

confirmed by the surrogate day assessment.

The conditio ns summarized above led to a build

- up of wildfire

- related emissions

in the Folsom area that contributed significantly to ozone formation on June 27.

The addition of wildfire

- related emissions caused ozone concentrations to rise

above levels typically meas ured at the Folsom site, resulting in a federal 1

- hour

ozone exceedance

. The surrogate day assessment shows that the

meteorological conditions present on June 27 would not be expected to result in

an exceedance (refer to Sonoma Technology, Inc., Appendix Y). Therefore, the

addition of the wildfire emissions was the primary cause of the exceedance on

this day.
