Water temperature in April for locations near Shelter Island Heights
Data source and citation
Raw data for the calculations made to find the sea surface temperature in Shelter Island Heights comes from the National Oceanic and Atmospheric Administration (NOAA) and their 1/4° daily Optimum Interpolation Sea Surface Temperature.
The water temperature data is constructed by combining observations from different platforms (satellites, ships, buoys, and Argo floats) on a regular global grid. A spatially complete sea surface temperature map is then built by interpolating to fill in gaps in the data.
