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
Parameters are passed using a GET request with a combination of path and optional query parameters. Accepted values are defined in the table below.
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}
The {begYear} and {endYear} parameters are optional. If they are not included, the entire period of record is returned.
https://www.ncei.noaa.gov/access/monitoring/climate-at-a-glance/{scope}/time-series/{region}/{parameter}/{surface}/{timescale}/{month}/data.{format}
Query Parameters
An optional query component may follow at the end of the URL path, preceded by a question-mark ?, in the form of key=value pairs, and separated by an ampersand &.
…?{basePeriod}=[true|false]&{basePeriodBegYear}=[year]&{basePeriodEndYear}=[year]
Note: A base period is used to calculate anomalies based on the average of the requested period. basePeriod is not applicable to Global Average Temperature Anomalies (parameter = tavg) since base periods are fixed for each region.
