Maximum sea surface temperatures (SST) around New Zealand over 1 Jan 2003 to 1 Jan 2024. Data modelled from single daily measurements from the MODIS-Aqua sensor (processed by NASA's Ocean Biology Processing Group). The underlying Level 3 data is a standard daily SST product with 4 km resolution, as sourced from NASA's Ocean Colour web portal (https://oceancolor.gsfc.nasa.gov/). Map projection: NZTM2000.
