El Nino-Southern Oscillation (ENSO) Data

Context

ENSO is a periodic fluctuation (i.e., every 2–7 years) in winds and sea surface temperatures over the tropical eastern Pacific Ocean, affecting the climate of many parts of the world. It is one of the main drivers of the interannual climate variability of Earth and can cause a wide range of climate anomalies. This dataset is to store ENSO indicators (variables related to ENSO) for better understanding and prediction of ENSO.

Content

The dataset contains ENSO-related standardized climate data from 1950 to 2023, collected from NOAA & NASA sites.
