Asymmetry and Diversity in the pattern, amplitude and duration of El Niño and La Niña
Years of record
- N/A
El Niño and La Niña, the two phases of ENSO, are sometimes described as opposites. However, there are asymmetries in their spatial structure, amplitude, duration and seasonal evolution. This leads to differing teleconnections and global impacts, as well as implications for ENSO predictability. The 'Expert Guidance' section of this post summarizes the metrics used to…

SODA: Simple Ocean Data Assimilation
Years of record
- to
The Simple Ocean Data Assimilation, or SODA, analysis is an ocean reanalysis data set consisting of gridded variables for the global ocean, as well as several derived fields. The goal is to provide an improved estimate of ocean state from those based solely on observations or numerical simulations.

Sea surface temperature (SST) data sets are an essential resource for monitoring and understanding climate variability and climate change. By surface area, SSTs are the dominant (~71%) input into merged global land-ocean surface temperature data products. Historically, SST measurments have been made from ships. Ship data have been compiled into…
