It provides a more detailed explanation of the air quality based on the pollutant values that were found.index.icon: This object represents the air quality level associated icon, if any. If there is no associated icon, the value will benull.index.color: This object represents the hexadecimal color code associated with the air quality level. It is used to visually represent the air quality level in various applications.index.value: This object represents the air quality level value, for numeric indexes only. If the index is not numeric, the value will benull.index.main_pollutants: This object represents an array of main pollutants identifiers. These pollutants are the main contributors to the air quality index value.pollutants: This object represents a dictionary of available pollutants at the requested point. It contains several sub-objects and values that describe the pollutants, includingshortcode,name,unit,found,value,confidence, andindex.pollutants.shortcode: This object represents the pollutant textual shortcode. It is a short abbreviation of the pollutant name that is used in various applications.pollutants.name: This object represents the full name of the pollutant.pollutants.unit: This object represents the unit in which the pollutant value is returned.pollutants.found: This object determines whether the pollutant value has been found. If the value istrue, it means that the pollutant value has been found. If it isfalse, it means that the pollutant value has not been found.pollutants.value: This object represents the value of the pollutant in the specified unit.pollutants.confidence: This object represents the pollutant value confidence. It indicates the level of confidence in the accuracy of the pollutant value.pollutants.index: This object represents the pollutant-specific index information. It contains several sub-objects and values that describe the index, includingindex_type.
The information provided in the table is useful for developers or data analysts who are working with Meersens' air quality conditions API. The table lists all the objects and their corresponding descriptions that are included in the API's JSON output. By having a clear understanding of these objects, developers can extract the required data more efficiently and analyze it to gain insights into air quality conditions. The detailed information about each pollutant, such as its name, unit, and value, can help in identifying air pollutants and their levels. Similarly, the air quality index and its associated information can help in assessing overall air quality conditions at a given location. Overall, this table provides a comprehensive overview of the data that can be accessed through the Meersens API, making it easier for developers to work with and make the most of the data.
JSON output
This is a JSON output that contains air quality data. The "found" key is set to true, indicating that data has been found. The "datetime" key specifies the date and time when the data was collected. The "index" key provides information about the air quality index, including the index type, index name, qualification (degraded in this case), color, icon, value, and main pollutants (in this case, pm25). The "pollutants" key contains information about various pollutants, including their shortcode, name, unit, value, and index. The pollutants include no2, co, o3, pm10, pm25, and so2. Finally, the "health_recommendations" key provides recommendations for various groups of people regarding the effects of air pollution on their health, such as respiratory discomfort, worsening of respiratory pathologies, and the potential impact on pregnancy and the elderly.
