Description:
Abstract:
The Oceanic Nino Index (ONI) is one of the primary indices used to monitor the El Nino-Southern Oscillation (ENSO). The ONI is calculated by averaging sea surface temperature anomalies in an area of the east-central equatorial Pacific Ocean, which is called the Nino-3.4 region (5S to 5N; 170W to 120W). Also, a 3-month time average (running mean) is calculated in order to better isolate variability closely related to the ENSO phenomenon.
Purpose:
Because it measures ENSO, the ONI is needed to understand the impacts of ENSO upon many global atmospheric and surface variables. Therefore, this information is critical for historical monitoring, predictions, and assessments.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Quality of the analysis relies on a temporally homogeneous, complete, gridded sea surface temperature dataset that assimilates available satellite and/or in situ networks.
Logical_Consistency_Report:
NA
Completeness_Report:
The dataset that used to create the ONI uses statistical methods that allow for stable reconstruction using sparse data.
