// Overview

NOAA PSL Climate Indices (Monthly Time Series)

The NOAA Physical Sciences Laboratory keeps one list of monthly atmospheric and ocean climate indices (PNA, NAO, SOI, ENSO indices, PDO, AMO, Arctic Oscillation and many more), each as a plain-text time series with its source and description.

Coverage

Global climate modes, monthly; series lengths vary. The list is titled "Climate Indices: Monthly Atmospheric and Ocean Time Series" and marks regularly updated series with an asterisk. Many series come from other groups, such as NOAA CPC or CRU, and each row names its source.

Verdict

One place to pull teleconnection and ENSO indices for weather, agriculture and energy agents. Check each series' source and update flag: some are no longer maintained. Licence: Custom (public-domain statement): the PSL disclaimer says "The information on government servers are in the public domain, unless specifically annotated otherwise, and may be used freely by the public so long as you do not 1) claim it is your own (e.g. by claiming copyright for NOAA information -- see below), 2) use it in a manner that implies an endorsement or affiliation with NOAA, or 3) modify it in content and then present it as official government material." Series from outside groups may carry their own terms. Rate limits: Not stated. Signal Lab links only.
