The temporal and spatial distributions of BLH were studied using data from a ceilometer, sodar, in situ meteorological measurements, and back-trajectory analyses. Generally, the BLH under continental sources is lower than that under marine sources. The BLH is featured with a shallow depth of 515 \u00b1 340 m under the Melbourne\/East Victoria continental source. Especially the mixed continental sources (Melbourne\/East Victoria and Tasmania direction) lead to a rise in radon concentration and lower BLH. In comparison, the boundary layer reaches a higher averaged BLH value of 730 \u00b1 305 m when marine air is prevalent. The BLH derived from ERA5 is positively biased compared to the ceilometer observations, except when the boundary layer is stable. The height at which wind profiles experience rapid changes corresponds to the BLH value. The wind flow within the boundary layer increased up to \u223c200 m, where it then meandered up to \u223c300 m. Furthermore, the statistic shows that BLH is positively associated with near-surface wind speed. This study firstly provides information on boundary layer structure in Cape Grim and the interaction with wind, which may aid in further evaluating their associated impacts on the climate and ecosystem.<\/jats:p>","DOI":"10.3390\/rs15020461","type":"journal-article","created":{"date-parts":[[2023,1,12]],"date-time":"2023-01-12T06:25:57Z","timestamp":1673504757000},"page":"461","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Observations of the Boundary Layer in the Cape Grim Coastal Region: Interaction with Wind and the Influences of Continental Sources"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3335-5444","authenticated-orcid":false,"given":"Zhenyi","family":"Chen","sequence":"first","affiliation":[{"name":"School of Ecology and Environment, Beijing Technology and Business University, Beijing 100048, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4230-717X","authenticated-orcid":false,"given":"Robyn","family":"Schofield","sequence":"additional","affiliation":[{"name":"School of Earth Sciences, University of Melbourne, Melbourne, VIC 3010, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9953-6806","authenticated-orcid":false,"given":"Melita","family":"Keywood","sequence":"additional","affiliation":[{"name":"Climate Science Centre, Oceans and Atmosphere, Commonwealth Scientific and Industrial Research Organization, Aspendale, VIC 3195, Australia"}]},{"given":"Sam","family":"Cleland","sequence":"additional","affiliation":[{"name":"Observing Systems and Operations, Bureau of Meteorology, Smithton, TAS 7330, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0568-8487","authenticated-orcid":false,"given":"Alastair G.","family":"Williams","sequence":"additional","affiliation":[{"name":"Australian Nuclear Science and Technology Organization, Sydney, NSW 2234, Australia"}]},{"given":"Stephen","family":"Wilson","sequence":"additional","affiliation":[{"name":"School of Earth, Atmosphere and Life Sciences, University of Wollongong, Wollongong, NSW 2522, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1135-1810","authenticated-orcid":false,"given":"Alan","family":"Griffiths","sequence":"additional","affiliation":[{"name":"Australian Nuclear Science and Technology Organization, Sydney, NSW 2234, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3544-9134","authenticated-orcid":false,"given":"Yan","family":"Xiang","sequence":"additional","affiliation":[{"name":"Institutes of Physical Science and Information Technology, Anhui University, Hefei 230031, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Stull, R.B.
