The first used the standard HSRL retrieval, and the second used only the total backscatter channel and a perturbation retrieval (PR). The motivation is to evaluate differences between the two techniques that would affect the decision of whether to use a simple backscatter lidar or a more complex HSRL in future applications. For the data set investigated, the attenuation coefficient from the PR was an average of 11% lower than that from the HSRL. The PR estimate of the scattering parameter decreased with depth relative to the HSRL estimate, although the overall bias was zero as a result of the calibration procedure. Near the surface, the coefficient of variability in both estimates of attenuation and in HSRL estimates of scattering were around 5%, but that in the PR estimate of scattering was over 10%. At greater depths, the variability increases for all of the profile parameters. The correlation between the two estimates of attenuation coefficient was 0.7. The correlation between scattering parameters was &gt; 0.8 near the surface, but decreased to 0.4 at a depth of around 20 m. Overall, the PR performed better relative to the HSRL in offshore waters than in nearshore waters.<\/jats:p>","DOI":"10.3390\/rs10122003","type":"journal-article","created":{"date-parts":[[2018,12,12]],"date-time":"2018-12-12T03:27:49Z","timestamp":1544585269000},"page":"2003","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":48,"title":["Ocean Backscatter Profiling Using High-Spectral-Resolution Lidar and a Perturbation Retrieval"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1586-2300","authenticated-orcid":false,"given":"James H.","family":"Churnside","sequence":"first","affiliation":[{"name":"NOAA Earth System Research Laboratory, Chemical Sciences Division, 325 Broadway, Boulder, CO 80305, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johnathan W.","family":"Hair","sequence":"additional","affiliation":[{"name":"NASA Langley Research Center, Hampton, VA 23681, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3364-4497","authenticated-orcid":false,"given":"Chris A.","family":"Hostetler","sequence":"additional","affiliation":[{"name":"NASA Langley Research Center, Hampton, VA 23681, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy Jo","family":"Scarino","sequence":"additional","affiliation":[{"name":"Science Systems &amp; Applications, Inc., Hampton, VA 23681, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"13","DOI":"10.1117\/1.OE.53.5.051405","article-title":"Review of profiling oceanographic lidar","volume":"53","author":"Churnside","year":"2013","journal-title":"Opt.
