Description
Returns a collection of weather history data for a Nielsen Designated Marketing Area (“DMA”).
Our patented OnPoint™ weather data is not confined to weather station locations, but is computed by overlaying multiple past weather sources (including weather station, satellite, radar, weather balloon, and model data – among others). The resulting quality-checked, error-corrected, and gap-filled data is uniquely derived for every DMA. This resource is available for 2007 onward.
Requires a subscription plan with the “read_history” and “access_dmas” capabilities to access this resource.
This resource is not available to free 30-day developer plans. However, postal code history is available. Please email sales@weathersource.com or call (844) 813-2617 if you need access to this resource.

Parameters
| timestamp_eq optional |
A response condition that returns a single element matching a timestamp. Either timestamp_eq or timestamp_between must be provided in ISO 8601 format. All timestamps are assumed local to the request location unless a UTC offset is provided (as part of the ISO 8601 format). The returned timestamp may not equal the provided value, but will be representative of the value. For example, if the period parameter is set to hour and the provided timestamp is for 8:15 a.m., the returned element will be for the 8 a.m. hour. Allowed Values: ISO 8601 timestamp Example Value: 2007-02-12T08:00-07:00 or 2007-02-12 |
|---|---|
| timestamp_between optional |
A response condition that returns a single element matching a timestamp. Either timestamp_eq or timestamp_between must be provided in ISO 8601 format. The total date range must not exceed 1 year in length. If a longer date range is required, multiple requests must be made. All timestamps are assumed local to the request location unless a UTC offset is provided (as part of the ISO 8601 format). The returned timestamp may not equal the provided value, but will be representative of the value. For example, if the period parameter is set to hour and the provided timestamp is for 8:15 a.m., the returned element will be for the 8 a.m. hour. Allowed Values: Two comma separated ISO 8601 timestamps Example Value: 2007-02-12T08:00-07:00,2007-02-12T23:00-07:00 |
