Recently,Professor Chang Liang from the College of Marine Sciences of Shanghai Ocean University (SHOU) and his collaborators have made significant progress inresearch on the characteristics of the Arctic planetary boundary layer height(PBLH) and its interaction with sea ice by using remote sensing based onmulti-source satellite platforms. The achievement, titled Characteristics of the Arctic planetary boundary layer height from multiple radio occultations,has been published online in IEEE Transactions on Geoscience and Remote Sensing(IEEE TGRS), a prestigious top international journal in the fields of geoscience and remote sensing (latest impact factor (IF)=8.2). SHOU is the signature unit of the first author and the only corresponding unit. Professor Chang Liang is the first author, and Professor Feng Guiping, also from the College of Marine Sciences, is the corresponding author.

By further consolidating existing results about surface air temperature (SAT), atmospheric precipitable water vapor (PWV), cloud fraction (CF), and so forth obtained by the Atmospheric Infrared Sounder (AIRS) in the Arctic planetary boundary layer,this study analyzes the correlation between PBLH and Arctic surface meteorological conditions under different Arctic sea ice conditions. It is found that the PBLH over the Arctic Ocean is consistently negatively correlated with sea ice concentration (SIC) and positively correlated with SAT and PWV.However, the responses of PBLH to changes in SIC, SAT, and PWV vary with seasonal changes in Arctic sea ice conditions. In addition, the unstable planetary boundary layer with high altitude in the open waters of the Arctic Ocean usually corresponds to a thin and weak atmospheric inversion layer; the planetary boundary layer with low altitude in solid ice regions is usually accompanied by highly stable ground inversions; and in terms of PBLH, ice edgeregions show transitional characteristics between open waters and solid iceregions.
