indexNino34

An analysis task for plotting both time series and spectra of the El Niño 3.4 Climate Index against observations.

Component and Tags:

component: ocean
tags: timeSeries, index, nino, publicObs

Configuration Options

The following configuration options are available for this task:

[indexNino34]
## options related to plotting time series of the El Nino 3.4 index

# Specified region for the Nino Index,'nino3', 'nino4', or 'nino3.4'
# The indexNino34 routine only accepts one value at a time
region = nino3.4

# Data source to read for comparison.  There are two options
# 1 - ERS_SSTv4 -- Extended Reconstructed Sea Surface Temperature -- 1854 - 2016
# 2 - HADIsst -- Hadley Center analysis -- 1870 - 2016
observationData = HADIsst

While the default is the El Niño 3.4 region, you may select among nino3, nino4, and nino3.4. See Regions for more information about regions in MPAS-Analyis.

By default, observations are taken from the Hadley Center analysis. To use the Extended Reconstructed Sea Surface Temperature (ERS SSTv4), set observationData = ERS_SSTv4.

Observations

• HadISST Nino 3.4 Index

• ERS SSTv4 Nino 3.4 Index
