observations_in_bbox
Pack: airnow · Endpoint: https://gateway.pipeworx.io/airnow/mcp
Historical AQI observations inside a bounding box for a date range. Specify pollutants as comma-separated parameter codes (e.g., “OZONE,PM25,PM10,CO,NO2,SO2”). bbox format: “minLon,minLat,maxLon,maxLat”.
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
bbox | string | yes | minLon,minLat,maxLon,maxLat |
start_date | string | yes | YYYY-MM-DDT00 (hour-granular ISO truncated) |
end_date | string | yes | YYYY-MM-DDT23 |
parameters | string | no | Comma-separated pollutants (default: OZONE,PM25,PM10) |
data_type | string | no | A (AQI) | C (concentration) | B (both, default) |
verbose | boolean | no | Include site / county / agency / full-AQS-code fields |
