  1. Recent Air Pollution and VolcanicMeasurements from OMPS Kai Yang, Eric Hughes, Russ Dickerson (UMCP) Simon Carn (MTU), Nick Krotkov(GSFC) Jun Wang (UNL) OMPS Science Team Meeting, December 5, 2013

  2. Smog Event over ChinaOctober 2013

  3. OMPS SO2 Measurements SO2 (DU)

  4. OMPS NO2 Measurements NO2 (1015cm-2)

  5. OMPS UV Aerosol Index UVAIb

  6. OMPS NO2 Retrieval Direct radiance fitting to retrieve NO2vertical columns • NO2: 345 – 378 nm • albedo, pressures, cloud fraction, aerosol index: 350 – 378 nm • Include BrO, HCHO, OCLO • Orbit-based strat-trop separation

  7. Why Directing Fitting? Air Mass FactorA.K.A Scattering Weight Red : wl = 340 nm Blue: wl = 380 nm Solid Lines: LER Ps = 922 hPa, Rs = 0.184 Dashed Lines: MLER Pt = 1013.25 hPa Pc = 800.00 hPa Rg = 0.08 Rc = 0.6 fc = 0.1 RCF= 0.22 @ 360 nm NO2 Profile Shape

  8. Orbit-based NO2Strat/Trop Separation NO2 (DU) Stratospheric NO2 Column: Excess (+) /Deficit (-), Jan 7, 2013

  9. Global Tropospheric NO2 Example Jan 7, 2013 NO2 (DU)

  10. Summary • OPMS NM provides high quality daily global measurements of air pollutants: SO2 and NO2

  11. Eruption of Kliuchevskoi Volcano (Kamchatka, Eastern Russia)10/19/2013

  12. Near-Real-Time OMPS SO2 Product Orbit: 10253 Low-res Orbit: 10252 Hi-res

  13. SO2 Over US: validation of OPMS with ground-based measurements

  14. Summary • OMPS volcanic SO2 processing is up-to-date. Plan to release this product via NASA OMPS web site: http://ozoneaq.gsfc.nasa.gov
