Poor air quality continues to hang over the football games scheduled across the region, with the Prairie-Salmon River, the Kamiah-Clearwater Valley. and the Clarkston-Grangeville game all postponed in administrative decisions this afternoon.

Many school districts evaluate outdoor events -- including games and practices -- based on AQI (air quality index). Air pollution is monitored by the state and the state's monitoring system reports when pollution has reached an "unhealthy" level. Some schools rely on the information shown by Idaho Department of Environmental Quality real-time monitoring stations, while others lean on airnow.gov. Public health officials, such as at Idaho Department of Health and Welfare, also point to a U.S. Forest Service wildland fire air quality monitoring website.

The sensors detect one of the major air quality pollutants: particulate matter (PM). But in some areas where there are no nearby sensors -- and there may be none more remote than Riggins -- school officials decide using the handy, if old-fashioned, way: eyeballing it. From IDHW's wildfire smoke guide for public health officials:

Visual Range and actions to take to reduce smoke exposure when wildfire smoke is in the air.

Using visual range to assess smoke levels in the interior western United States

Many communities do not have access to continuous PM monitoring and may need other ways to evaluate local air quality. Visual range (i.e. how far can be seen?), like other instantaneous monitoring approaches can inform and help the public respond to smoky conditions. This is true even in areas that have continuous monitors, because smoke concentrations can vary widely within a couple miles and can change rapidly.

Basic Approach:

To determine visual range, one must:

• Use this method only during daylight hours (avoid sunrise and sunset).

• Use this method only if relative humidity is less than 65 percent.

• Focus on the darkest object (e.g. black is better than green)

• Determine the limit of visual range by looking for targets at known distances (miles). The visible range is the point at which even high-contrast objects (e.g., a dark forested mountain viewed against the sky at noon) totally disappear.

• After determining visual range in miles, use Table 1 to identify actions to take to reduce exposure.

Often, it is difficult to assess “the point at which even high-contrast objects (e.g., a dark forested mountain viewed against the sky at noon) totally disappear.” Instead, it may be more useful to use known landmarks at a given distance away to assess possible visual ranges. For example, target A is two miles away and visible, but target B, which is four miles away, is not visible Therefore the visual range is somewhere between two miles and four miles. Use Table 1 to identify the range of actions to consider to reduce smoke exposure.

So that's a bit about how school officials decide. Check back later today about what they decide.

WHERE WE'LL BE

COTTONWOOD - Weather permitting, this will be our first live look at two of the teams in our coverage area this season. The matchup appears to hinge mainly on how well Prairie's defensive line plays against Salmon River's offensive line. Salmon River's key back -- Canyon Harper -- has run wild in two games against lesser teams, while Prairie's offense never really got on track last Friday night on Whitepine League frontrunner Genesee's field. (Lapwai, which improved to 2-0 in the WPL with a win over Troy last night, is presently a half-game ahead of Week Two winners Genesee and Wallace.)

[UPDATE (1:30 p.m.): The Salmon River-Prairie game has been cancelled and will not be rescheduled. -ao]

[UPDATE (3:30 p.m.): The Salmon River-Prairie game has been rescheduled for Monday evening, Sept. 11. -ao]

AROUND THE LEAGUES

At Kamiah, the Kubs will host Clearwater Valley -- weather permitting -- for what has been a rivalry game ever since the Kubs first set foot in the 1AD1 classification. A win would be the first of the season for either team, but while the opportunity for Kamiah would be to keep a clean league record, the Rams' chance is to level theirs after last week's loss to Wallace.

[UPDATE (1:15 p.m.): The Kubs-Rams game has been rescheduled for 6 p.m. tomorrow night, Sept. 9, weather permitting. -ao]

MORE TO SEE

At Clarkston, Grangeville will -- weather permitting -- measure itself against a team that last week beat a team that beat the Bulldogs back in Week One. This game will be radio broadcast on AM 1230 and FM 92.7.

[UPDATE (3 p.m.): Grangeville and Clarkston will decide whether to proceed by 3:45 p.m. -ao]

[UPDATE (3:15 p.m.): Grangeville's soccer games tomorrow against Priest River have been cancelled, and AD Matt Dame said they may be rescheduled. "We are looking into that next week," Dame said. -ao]

[UPDATE (4 p.m.): Grangeville's football night has been postponed. The game may be played tomorrow, if air quality improves, or may be pushed back to Monday, GHS principal Randall Miskin told the Free Press Friday. For now, the game has been rescheduled to noon Saturday, Sept. 9, at Clarkston. -ao]
