Sea Level Articles
NASA has numerous datasets and resources for monitoring sea level change. The Sea Level Change Data Pathfinder, geared for new users, provides direct links to commonly-used datasets and links to tools for visualizing and analyzing the data.
According to the United Nations, 40% of the world's population lives within 100 km of a coast, meaning that close to three billion people could be impacted by changes in sea level. Coastal communities are centers of economic, social, and cultural development; they also provide significant ecological and environmental services. Global mean sea level (GMSL) is increasing at about 3.3 mm/yr and is already having catastrophic effects in coastal communities through flooding, erosion, and storm-related hazards.
These articles, many from the Sensing Our Planet series, highlight some of these efforts. To meet some of the scientists using Earthdata for sea level change research and applications, see our Data User Profiles.
The Precision Behind Sea Level Rise
Knowing the precise location of a satellite in space is critical for determining sea surface height and, through this, the rate of global mean sea level rise.
Solving the Data Puzzle of Sea Level Rise
The new Sea Level Change Data Pathfinder highlights the diversity of datasets used to piece together the status and drivers of sea level rise.
