2. © Imperial College LondonPage 2 Outline PAVE –Look at IRR, IPR files (net ozone production) –Tidy plots ppb, titles –Vertical plot of net ozone production –Run pave from script ppb + wind vector

3. © Imperial College LondonPage 3 Look at IRR and IPR files Add the IRR and PA files to the dataset list ~/demo-cmaq/data/cctm/CCTM_sof_CONC.D4.2003196.ncf ~/demo-cmaq/data/cctm/CCTM_sof_PA_1.D4.2003196.ncf ~/demo-cmaq/data/cctm/CCTM_sof_IRR_1.D4.2003196.ncf Create tile plots of OzoneO3 net ozone O3net production of RO2prodRO2 Ozone dry depositionDDEP_O3

5. © Imperial College LondonPage 5 Ozone plot in ppb In Add/delete/Select Formula box Enter New Formula O3a*1000 Add Create a new tile plot Change units label to ppb titles scale

8. © Imperial College LondonPage 8 Vertical plots – select area of interest Using O3net from the IRR file. Select the area of interest Datasets Select layer ranges - move sliders to required range Datasets Select region of interest - blue = selected area Edit Select None - all white Click on squares to identify row of interest - select row 28 using the mouse If odd unwanted squares are still blue click on them again to deselect (turn them white) – otherwise it will fail.

9. © Imperial College LondonPage 9 Vertical plots – cross-section type Graphics set tile plot cross-section type select 'Y' plot Graphics create tile plot Set scale to max 0.005 min -0.02

10. © Imperial College LondonPage 10 Vertical plots – cross-section type Create 2 more vertical plots prodRO2 from IRR file Set scale to max 0.003 min 0 O3 from CONC file Set scale to max 0.07 min 0 Graphics animate simultaneously

11. © Imperial College LondonPage 11 Vertical plots – reset cross-section You need to reset values to return to normal tile plots Select 1 layer Select region of interest And set tile plot cross-section to go back to normal plots Graphics set tile plot cross-section type select ‘z' plot
