Latest El Niño/La Niña Watch Data
LATEST IMAGES - 12/05/2014
These are the latest images from the OSTM/Jason-2 satellite. Jason-2 continues providing the uninterrupted time-series that originated with TOPEX/Poseidon. Jason is using radar altimetry to collect sea surface height data of all the world's oceans. These images are processed to highlight the interannual signal of sea surface height. The mean signal, seasonal signal, and the trend have been removed.
What is sea-surface height?
What are we looking at?
These images show sea surface height anomalies with the seasonal cycle (the effects of summer, fall, winter, and spring) removed. The differences between what we see and what is normal for different times and regions are called anomalies, or residuals. When oceanographers and climatologists view these "anomalies" they can identify unusual patterns and can tell us how heat is being stored in the ocean to influence future planetary climate events.
Each image is a 10-day average of data, centered on the date indicated.
