This dataset contains the Global Mean Sea Level (GMSL) trend generated from the Integrated Multi-Mission Ocean Altimeter Data for Climate Research (GMSL dataset). The GMSL is a 1-dimensional time series of globally averaged Sea Surface Height Anomalies (SSHA) from TOPEX/Poseidon, Jason-1 and OSTM/Jason-2. It starts in September 1992 to present, with a lag of up to 4 months. All biases and cross-calibrations have been applied to the data so SSHA are consistent between satellites. Glacial Isostatic Adjustment (GIA) has been applied. These data are available in ASCII format. Reference: Beckley et al., 2010, DOI: 10.1080/01490419.2010.491029.
The flow speeds of Antarctica's fastest-accelerating glaciers in 2008-2014 likely increased because of warm water blown into their bay by La Niña and another climate pattern.
For the first time, scientists have detected sea level "fingerprints" – patterns of variation in global sea level due to changes in water and ice on land – in GRACE data.
Satellite imagery from NASA's Aqua satellite and NASA-NOAA's Suomi NPP satellite have provided data on the still Category 5 Hurricane Irma
Irma made landfall twice on Sept. 10, first in the Florida Keys and then near Naples. Satellites provided daytime and night-time views of the storm.
A NASA geophysicist has found that sea level rise is triggering occurrences of minor nuisance flooding along coastlines.
