Monthly Satellite Sea Surface Temperature Climatology of the Canadian Pacific Exclusive Economic Zone (2003-2020) – 1 km Resolution

Monthly Satellite Sea Surface Temperature Climatology of the Canadian Pacific Exclusive Economic Zone (2003-2020) – 1 km Resolution MODIS-Aqua night long-wave Sea Surface Temperature (SST) images were acquired from the NASA Ocean Biology Processing Group at processing Level-2 (version 2018), 1-km resolution, spanning the period 2003-01-01 to 2020-12-31. Image pixels were aligned and mapped to a regular grid using the SeaDAS program, retaining all pixels with a quality level of ‘1’ or lower, which is recommended for scientific analysis. The monthly mean value at all pixels was calculated for individual years, and used to produce maps of the monthly climatological mean and standard deviation of SST. Additionally, the number of occurrences of valid data at each pixel over the period of observation were calculated. Pixels with fewer than two occurrences over the entire period of observation were removed from these maps, and set to a NaN value in the tif files. A few small gaps between pixels (near the edges of individual images) were filled using the median value of surrounding pixels, provided there were greater than 4 values. Finally, all rasters were cropped to the Canadian Exclusive Economic Zone and assigned to the NAD83 geographic coordinate reference system (EPSG:4269), and have a final pixel resolution of approximately 0.01 degrees. The monthly mean, monthly standard deviation, and number of occurrences for all pixels are provided. 2024-02-15 Fisheries and Oceans Canada Charles.Hannah@dfo-mpo.gc.ca Nature and EnvironmentScience and TechnologyClimatologyOceansClimate Data DictionaryHTML https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Monthly_Satellite_SST_Climatology_CPEEZ_2003_2020_1km/Data_Dictionary_EN_FR_Monthly_satellite_SST_climatology_CPEEZ_2003-2020_1km.htm ReferencesHTML https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Monthly_Satellite_SST_Climatology_CPEEZ_2003_2020_1km/References_EN_FR_Monthly_satellite_SST_climatology_CPEEZ_2003-2020_1km.htm Satellite Sea Surface Temperature Monthly Mean 2003-2020 - 1km resolution - GeoTIFGeoTIF https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Monthly_Satellite_SST_Climatology_CPEEZ_2003_2020_1km/SST_1km_2003_2020_monthly_mean_tif_files.zip Satellite Sea Surface Temperature Monthly Mean 2003-2020 - 1km resolution - PNGPNG https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Monthly_Satellite_SST_Climatology_CPEEZ_2003_2020_1km/SST_1km_2003_2020_monthly_mean_png_files.zip Satellite Sea Surface Temperature Monthly Standard Deviation 2003-2020 - 1km resolution - GeoTIFGeoTIF https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Monthly_Satellite_SST_Climatology_CPEEZ_2003_2020_1km/SST_1km_2003_2020_monthly_stdev_tif_files.zip Satellite Sea Surface Temperature Monthly Standard Deviation 2003-2020 - 1km resolution - PNGPNG https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Monthly_Satellite_SST_Climatology_CPEEZ_2003_2020_1km/SST_1km_2003_2020_monthly_stdev_png_files.zip Satellite Sea Surface Temperature Monthly Number of Occurrences 2003-2020 - 1km resolution - GeoTIFGeoTIF https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Monthly_Satellite_SST_Climatology_CPEEZ_2003_2020_1km/SST_1km_2003_2020_monthly_numtotal_tif_files.zip Satellite Sea Surface Temperature Monthly Number of Occurrences 2003-2020 - 1km resolution - PNGPNG https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Monthly_Satellite_SST_Climatology_CPEEZ_2003_2020_1km/SST_1km_2003_2020_monthly_numtotal_png_files.zip Monthly Satellite Sea Surface Temperature Climatology of the Canadian Pacific Exclusive Economic Zone (1981-2010) – 4 km ResolutionHTML https://open.canada.ca/data/en/dataset/cec45ade-3647-4aec-84f1-8cb68dd305c2 Monthly Satellite Sea Surface Temperature Climatology of the Canadian Pacific Exclusive Economic Zone (1990-2020 ) – 4 km ResolutionHTML https://open.canada.ca/data/en/dataset/a67df54b-286d-4eb6-9b38-474f1efe86db Satellite Sea Surface Temperature Monthly Mean 2003-2020 - 1km resolutionESRI REST https://gisp.dfo-mpo.gc.ca/arcgis/rest/services/FGP/Monthly_Satellite_SST_Climatology_CPEEZ_2003_2020_1km/MapServer Satellite Sea Surface Temperature Monthly Mean 2003-2020 - 1km resolutionESRI REST https://gisp.dfo-mpo.gc.ca/arcgis/rest/services/FGP/Monthly_Satellite_SST_Climatology_CPEEZ_2003_2020_1km/MapServer
