2022/2023 MLUPCM 

The 2022/2023 MLUPCM is designed to address the critical knowledge gaps of the ozone chemistry dynamics in the urban plume in the lowest layer under the influence from the coastal meteorology over Long Island, and plan to fully coordinate with and complement the aircraft measurements through mobile measurements in 2023. 

A pilot study was executed during August 2022 to obtain basic and necessary information about the transport of urban plumes, the movement of the sea breeze, and the rationality of the mobile lab routes. All these would provide support for the 2023 intensive measurements to better fill gaps in the ozone chemistry dynamics of the urban plume in the lowest layer, and complement the AEROMMA, GOTHAAM and CUPiDS aircraft measurements and other stationary field studies. During August, a total of eight on-road measurements were executed, including 6 daytime and 2 nighttime. Each on-road measurement was over 6 hours, covering the major regions of western Long Island during the daytime, and the regions surrounding Long Island Sound during the nighttime. The initial results are still under analysis and will be discussed with the scientific community participating in the above aircraft projects and also with environmental agencies, i.e., EPA, New York State Department of Environmental Conservation (NYS DEC), for better cooperation in 2023.
