WeatherDotgov Agent

This agent provides the ability to query for current and forecast weather data from NOAA. The agent extends BaseWeatherAgent that provides caching of recently requested data, as well as mapping of weather point names from NOAA's naming scheme to the standardized CF-conventions scheme.


The WeatherDotgov agent requires the Pint package. This package can be installed in an activated environment with:

pip install pint


The following is an example configuration for the agent. All configuration parameters are optional.


  1. "database_file" - sqlite database file for weather data caching. Defaults to "weather.sqlite" in the agent's data directory

  2. "max_size_gb" - maximum size of cache database. When cache exceeds this size, data will get purged from cache until the cache is within the configured size.

  3. "poll_locations" - list of locations to periodically poll for current data

  4. "poll_interval" - polling frequency or the number of seconds between each poll.

        "database_file": "weather.sqlite",
        "max_size_gb": 1,
        "poll_locations": [{"station": "KLAX"}, {"station": "KPHX"}],
        "poll_interval": 60

Registry Configuration

The registry configuration file for this agent can be found in agent's data directory. This configuration provides the point name mapping from NOAA's point scheme to the CF-conventions scheme by default. The file leaves the unit name columns for each point blank, as this agent does not include unit conversion. Points that do not specify 'Standard_Point_Name' were found to not have a logical match to any point found in the CF-Conventions. For these points NOAA point names (Service_Point_Name) will be used.


The WeatherDotGov agent does not utilize an API key, as NOAA allows users to gather weather data for free, and does not provide nor require keys.

This implementation of the weather agent does not include historical weather data, as NOAA does not provide an accessible endpoint from which historical data may be obtained.

Data provided by NOAA is in a nested dictionary format. The base weather agent does not handle unit conversion for arbitrary nested dictionary format and hence this agent does not support unit conversion at this time.
