Global Time Series

Overview

A RESTful application programming interface (API) is available to access Climate at a Glance data. The API can format desired data as comma-separated values (CSV), JavaScript Object Notation (JSON), and Extensible Markup Language (XML). The Data Service is only available via HTTP Strict Transport Security (HSTS) following Federal government policy.

Request Endpoint Parameters

Accepted values are defined in the table below.

Required Parameters

Required parameters are passed as path parameters.

https://www.ncei.noaa.gov/access/monitoring/climate-at-a-glance/global/time-series/{region}/{parameter}/{surface}/{timescale}/{month}/{begYear}-{endYear}/data.{format}

Optional Parameters

Note: not applicable to Average Temperature Anomalies (parameter = tavg)

Optional parameters are passed using a GET request. This an optional query component which follows the path, preceded by a question-mark ?, in the form of key=value pairs, and separated by an ampersand &.

Please note, global and hemispheric temperature anomalies are with respect to the 1901-2000 average. Coordinate temperature anomalies are with respect to the 1991-2020 average. All other regional temperature anomalies are with respect to the 1910-2000 average. Monthly precipitation data are not available until a few days after temperature data are released.
