Question

Numerical simulations of this property are conducted with the open source software suite CMAQ (“C-mack”). The prescribed “reference methods” or “equivalent methods” for measuring this property include samplers that separate the input with virtual impactors, beta gauges, and tapered element oscillating microbalances. When this property is low, the crustose (“crust-ose”) organisms Lepraria incana (“leh-PRA-ree-ah in-KA-na”) and Lecanora conizaeoides (“leh-ka-NOR-ah CO-nih-zay-OY-deez”) thrive. The standard scale for reporting this property ranges from 0 to 500, with 500 meaning this property is dangerously low. This property declines as concentrations of PM2.5 (10[1])(“P-M-two-point-five”) and PM10 (“P-M-ten”) rise. (10[1])The common (10[1])bioindicators (10[1]-5[1])for this property are bryophytes (“BRY-oh-fites”) and lichens (-5[1])(“LIKE-ens”). The EPA’s (10[1]-5[1])national (10[1])standards (-5[1])for ambient values of this property place upper limits on the amount of particulate matter (10[3])and ground (10[1])level ozone. (10[1]-5[1])For 10 points, name this property that is low when there is haze, (10[3]-5[1])smog, (-5[1])or acid (10[1])rain. (10[1])■END■ (10[3]0[3])

ANSWER: air quality [prompt on descriptions of how clean the air is or how breathable the air is; reject “air pollution”] (The 0-to-500 scale is the US’s Air Quality Index, or AQI.)
