Sea surface temperature (SST), or ocean surface temperature, is the water temperature close to the ocean's surface. The exact meaning of surface varies according to the measurement method used, but it is between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface.

This page provides time series and map visualizations of daily mean Sea Surface Temperature (SST) from NOAA Optimum Interpolation SST (OISST) version 2.1. OISST is a 0.25°x0.25° gridded dataset that provides estimates of temperature based on a blend of satellite, ship, and buoy observations.

Climbing sea surface temperatures receive a lot of attention, but ocean heat does not only stay at the sea surface. Global ocean circulation slowly moves those warm water molecules from the surface to the deep ocean, where slow (but important) warming also takes place.

2025年1月15日 · Sea surface temperature—the temperature of the water at the ocean surface—is an important physical attribute of the world’s oceans. The surface temperature of the world’s oceans varies mainly with latitude, with the warmest waters generally near the equator and the coldest waters in the Arctic and Antarctic regions.

The NOAA geo-polar blended SST is a daily 0.05° (~5km) global high resolution satellite-based sea surface temperature (SST) Level-4 analyses generated on an operational basis. This analysis combines SST data from US, Japanese and European geostationary infrared imagers, and low-earth orbiting infrared (U.S. and European) SST data, into a ...

Sea surface temperature is defined as the average temperature of the top few millimeters of the ocean. Sea surface temperature monitoring tells us how the ocean and atmosphere interact, as well as providing fundamental data on the global climate system.

Sea Surface Temperature (SST) is one of the Essential Climate Variables (ECVs) defined by the Global Climate Observing System (GCOS) to monitor and characterise the state of the global climate system.

What is Ocean Temperature? Ocean Temperature is a measure of the energy due to the motion of molecules in the ocean. Satellites enable measurement of sea surface temperature (SST) from approximately 10 µm below the surface (infrared bands) …

2023年5月8日 · This visualization shows Sea Surface Temperature (SST) data from the Jet Propulsion Laboratory (JPL) Multi-scale Ultra-high Resolution (MUR) Sea Surface Temperature Analysis. The analysis data is near-real-time (one day latency) and the visualization is updated daily to include the latest available data.

2024年6月16日 · Because the ocean covers 71 percent of Earth's surface, scientists record sea surface temperature (SST) to understand how the ocean communicates with Earth's atmosphere. SST provides fundamental information on the global climate system.
