Annex 2: PM modelling in the UK Figure A2.1.1: Daily average and hourly maxima for PM10 from 19-25 April 2011 from the UK daily air quality forecast. 147
PM2.5 in the UK 148 2. Figure A2.1.1 shows the moderate levels of PM building up and subsiding over a series of days. This is demonstrated in Figure A2.1.2 which gives an extract from the model evaluation of 16 Automatic Urban and Rural Network (AURN) urban background sites from around the UK for the period 12-26 April 2011. The evaluation is based on hourly values and during this period model performance was within acceptable limits as defined by the Model Evaluation Protocol (Derwent et al., 2009a). Table A2.1.1 summarises the model performance for a selection of rural, urban background and urban AURN sites. ugm -3 ugm -3 100 90 80 70 60 50 40 30 20 10 0 100 90 80 70 60 50 40 30 20 10 0 2011-04-12 2011-04-12 Observation Model 2011-04-13 2011-04-13 Observation Model 2011-04-14 2011-04-14 2011-04-15 2011-04-15 2011-04-17 2011-04-17 2011-04-18 2011-04-18 Figure A2.1.2: Evaluation of CMAQ forecast with hourly PM10 provisional data from 16 AURN urban background sites, 12-26 April 2011. 2011-04-19 2011-04-19 2011-04-20 2011-04-21 2011-04-21 2011-04-22 2011-04-22 2011-04-23 2011-04-23 2011-04-24 2011-04-24 2011-04-25 2011-04-25 2011-04-26 2011-04-26
