2. Bias of All Pairs >60 ppb(D60)

where

D60 = non-normalized bias from all hourly

prediction-observation pairs for observed

values >60 ppb

NT = total number of station-hours (defined

previously)

N = number of monitoring stations

Hi = number of hourly prediction-observation pairs

for monitoring station i

co(i,j) = observed value >60 ppb at monitoring station

i for hour j

cp(i,j) = predicted value at monitoring station i for

hour j

3. Bias of All Station Peaks (Dpeak)

where

Dpeak = non-normalized bias from all predictionobservation

pairs for peak observed values

at all monitoring stations

N = number of monitoring stations

co(i,ti) = peak observed value at monitoring station i

for hour ti)

cp(i,ti) = predicted value at monitoring station i for

hour ti

ti = hour of peak observed value at monitoring

station i

4. Fractional Bias for Peak Concentration
