      Key Points

      • Nitrous acid measured in urban atmosphere via laser absorption spectroscopy
      • Day HONO near emission source not at PSS, misinterpreted as secondary production
      • Night HONO:NOx cannot be used to infer production without counting NO2 oxidation

      Olga Pikelnaya, James H. Flynn, Catalina Tsai and Jochen Stutz

      Article first published online: 15 AUG 2013 | DOI: 10.1002/jgrd.50643

      Key Points

      • Burning petrochemical flares emit formaldehyde at rates of 0.3-2.5 kg/hr
      • Co-emission of formaldehyde and sulphur dioxide from flares was not observed
      • Small flares were observed, larger flares are expected to emit more HCHO

      Birnur Buzcu-Guven, Eduardo P. Olaguer, Scott C. Herndon, Charles E. Kolb, W. Berk Knighton and Alex E. Cuclis

      Article first published online: 26 JUL 2013 | DOI: 10.1002/jgrd.50586

      Key Points

      • Benzene source apportionment with inverse model and PMF is in agreement.
      • Self-reported emissions from the industrial facility are underestimated.
      • Besides flares, tanks and aromatic units are significant sources of benzene.

      Article first published online: 7 JUN 2013 | DOI: 10.1002/jgrd.50342

      Key Points

      • The model reproduced the measured OH and HO2 with all five chemical mechanisms.
      • HOx production was dominated by HONO photolysis in the early morning.
      • P(O3) was VOC sensitive in the morning and NOx sensitive for most of afternoon.
    6. Application of an adjoint neighborhood-scale chemistry transport model to the attribution of primary formaldehyde at Lynchburg Ferry during TexAQS II (pages 4936–4946)

      Eduardo P. Olaguer

      Article first published online: 28 MAY 2013 | DOI: 10.1002/jgrd.50406

      Key Points

      • Inverse modeling of HCHO and olefins was performed
      • Inferred emissions compare well with remote sensing measurements
      • Primary HCHO is significant
    7. Source apportionment of formaldehyde during TexAQS 2006 using a source-oriented chemical transport model (pages 1525–1535)

      Hongliang Zhang, Jingyi Li, Qi Ying, Birnur Buzcu Guven and Eduardo P. Olaguer

      Article first published online: 13 FEB 2013 | DOI: 10.1002/jgrd.50197

      Key Points

      • Determine regional source contributions to primary and secondary HCHO using CMAQ
      • 20-30% of total HCHO is primary, from vehicles, natural gas and biogenic sources
      • 70-80% of total HCHO is secondary, mainly due to biogenic and upwind sources

      Key Points

      • Observed/modeled PBLHs are lower during nighttime/morning on high ozone days
      • Observed PBL growth rates are lower during early morning on high ozone days
      • Observed mixing parameters are 2-3 times weaker on high ozone days

      Key Points

      • HONO was measured by six techniques during SHARP under polluted urban conditions
      • Methods with collocated inlets tracked each other most closely
      • Differences between techniques not likely explained by chemical interference alone
