FILE Job Example: AirNow Climate and Pollution Statistics
Overview
Download pollution statistics from airnow.gov for a collection of cities and metropolitan areas in the U.S.
The Path field contains the ${ITEM} placeholder to allow multiple areas, defined in an item list, to be queried by one configuration.
The $TIME() function is used to set a relative time interval, 15 days, from the current time to override provisional (estimated) data with revised values.
Each element in the item list serializes multiple settings in one string such as bounding box coordinates, city name, and metric prefix.
API key is required to access this data source.
The configuration uses the HTTP pool to increase timeout to 180 seconds.
