• Description:
  Mixing layer height (MLH) and land-sea breeze in the coastal area play an important role in ozone (O3) dispersion and transport. This study presents the multiple-platform observations of MLH dynamics for a high O3 event during Long Island Sound Tropospheric Ozone Study (LISTOS) in summer 2018. The diurnal evolution and spatial variability of MLH are observed from ground-based aerosol Lidar, Vaisala Ceilometer, Coherent Doppler Wind Lidar, and airborne lidar in New York City (NYC) urban and the coastal area in Long Island on August 28–29, 2018. The results indicate that the MLH growth in the morning shows a time lag of 1–2 h in the coastal area versus that in the NYC urban area. The spatial gradient variation of MLH from the urban to the coastal area is demonstrated from the NASA High Altitude Lidar Observatory (HALO) airborne high spectral resolution lidar (HSRL) observations by showing lower values in the coastal and marine area. Meanwhile, the ground O3 are consistently much higher at noon in the coastal sites than those in the NYC urban sites reaching the maximum value of 100–120 ppb in exceedance of the O3 NAAQS, which is closely relevant to the urban pollutant transport, MLH dynamics, and sea breeze. The observation data are further used to assess the model product of PBLH and O3 at the NYC urban and coastal sites.
