The interpolated GlobColour product provided by the Copernicus Marine Environment Monitoring Service (CMEMS) meets these requirements by being \u2018gap filled\u2019, thus yielding the highest spatial coverage. Despite being validated on a global scale, a regional comparison to in situ Chl-a concentrations should be conducted to enable product application in optically complex waters. This study aims to evaluate the performance of the GlobColour interpolated product in British Columbia coastal waters via a statistical match-up analysis and a qualitative analysis to determine whether the data reflect the region\u2019s large-scale seasonal trends and latitudinal dynamics. Additionally, the statistical performance of the GlobColour interpolated product was compared to the original GlobColour and Ocean Colour Climate Change Initiative (OC-CCI) merged chlorophyll-a products based on in situ observations. The GlobColour interpolated product performed relatively well and was comparable to the best-performing product for each water type (RMSE = 0.28, r2 = 0.77, MdAD = 1.5, BIAS = 0.90). The statistics for all the products degraded in Case 2 waters, thus highlighting the dilemma of applying algorithms designed for Case 1 waters in Case 2 waters. Our results indicate how the quality of products can vary in different environmental conditions.<\/jats:p>","DOI":"10.3390\/rs15030687","type":"journal-article","created":{"date-parts":[[2023,1,25]],"date-time":"2023-01-25T04:22:16Z","timestamp":1674620536000},"page":"687","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Merged Multi-Sensor Ocean Colour Chlorophyll Product Evaluation for the British Columbia Coast"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1786-9178","authenticated-orcid":false,"given":"Sejal","family":"Pramlall","sequence":"first","affiliation":[{"name":"Spectral Lab., Department of Geography, University of Victoria, Victoria, BC V8P 5C2, Canada"}]},{"given":"Jennifer M.","family":"Jackson","sequence":"additional","affiliation":[{"name":"Hakai Institute, Victoria, BC V8W 1T4, Canada"},{"name":"Fisheries and Oceans Canada (DFO), Sidney, BC V8L 5T5, Canada"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1145-9127","authenticated-orcid":false,"given":"Marta","family":"Konik","sequence":"additional","affiliation":[{"name":"Spectral Lab., Department of Geography, University of Victoria, Victoria, BC V8P 5C2, Canada"},{"name":"The Institute of Oceanology, Polish Academy of Sciences, 81-712 Sopot, Poland"}]},{"given":"Maycira","family":"Costa","sequence":"additional","affiliation":[{"name":"Spectral Lab., Department of Geography, University of Victoria, Victoria, BC V8P 5C2, Canada"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1431","DOI":"10.1175\/BAMS-D-13-00047.1","article-title":"The Concept of Essential Climate Variables in Support of Climate Research, Applications, and Policy","volume":"95","author":"Bojinski","year":"2014","journal-title":"Bull.
