State of the Climate Monthly Overview - Global El Niño/Southern Oscillation
Sample image of El Niño/Southern Oscillation
The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - Global El Niño/Southern Oscillation report describes atmospheric and oceanic conditions related to ENSO, a periodic fluctuation in sea surface temperature (El Niño) and the air pressure of the overlying atmosphere (Southern Oscillation) across the equatorial Pacific Ocean. Each report provides a status statement and descriptions of the following indicators: 1) Sea surface temperatures (SSTs) and mixed-layer conditions; 2) Equatorial zonal winds (U-component winds) and sea-level topography; 3) Outgoing longwave radiation (OLR); and 4) Southern oscillation index (SOI). Reports were written monthly from January 2004 through October 2009 with annually summaries for 2003-2008. As of the October 2009 report, NCDC no longer wrote a separate assessment of the current state of El Niño/Southern Oscillation as part of its monthly climate report. The information is incorporated in the El Niño Diagnostic Discussion produced each month by the NOAA Climate Prediction Center.

NCEI/NCEI Climate Monitoring
The Climate Monitoring mission is to monitor and assess the state of the Earth's climate in near real-time, providing decision-makers at all levels of the public and private sectors with data and information on climate trends and variability including perspectives on how the climate of today compares to the past. The web page provides access to available reports and products.

| Supplemental Information |
As of the October 2009 report, NCDC will no longer write a separate assessment of the current state of El Niño/Southern Oscillation as part of its Monthly Climate Report. This information will be incorporated in the El Niño Diagnostic Discussion produced each month by the NOAA Climate Prediction Center. |
| Purpose |
This State of the Climate report provides decision-makers at all levels of the public and private sectors with data and information on climate trends and variability each month, season, and year for the United States, including perspectives on how the climate of today compares to the past. |

- Please note that State of the Climate reports are based upon operational datasets. The official operational datasets chosen for the report can and do change over time. The nature of these changes can be evolutionary, such as addition of previously-missing data or changes due to quality-assurance algorithms. Changes may also be revolutionary, in that a new version of an operational dataset, or a different dataset altogether, are adopted for official use. In any of these cases, the values presented in the State of the Climate reports reflect those known at the time, using the official dataset at the time. Values are not updated or edited within past reports, unless otherwise noted, even if the underlying official dataset has since changed.

| Lineage Statement |
NCEI datasets are generally used as primary source data for the monthly narrative. However, for some phenomena not entirely captured by these datasets, trusted external data and analyses are used to supplement primary data sources. |

| Processing Steps |
- 2015-04-22T00:00:00 - NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
