Air Pollution API

This API allows you to retrieve the current, forecast and historic ultraviolet index (UV index).

Corresponding OpenWeatherMap documentation:

Usage​

  • $type: Can be one of "O3", "NO2", "SO2", or "CO".
  • $lat / $lng: Latitude and longitude must be provided as strings, because the number of digits after the decimal point determines the search radius. Specifying more digits leads to closer results, but too many digits can lead to no result at all.
  • $date: Date to retrieve data from. "current" requests the newest available information. You can also specify a date in ISO 8601 format. More information on that can be found in the OpenWeatherMap documentation.
// $type =
$co = $owm->getAirPollution($type, $lat, $lng, $date = "current");

The return value depends on the $type and is discussed in the next sections.

Carbon Monoxide (CO)​

$co = $owm->getAirPollution("CO", "52", "13");
if ($co === null) {
    // No data available
} else {
    foreach ($co->values as $data) {
        echo $data["value"];
        echo $data["value"]->getPrecision();
        echo $data["pressure"];
    }
}

Ozone (O3)​

$o3 = $owm->getAirPollution("O3", "52", "13");
if ($o3 === null) {
    // No data available
} else {
    echo $o3->value;
}

Nitrogen Dioxide (NO2)​

$no2 = $owm->getAirPollution("NO2", "52", "13");
if ($no2 === null) {
    // No data available
} else {
    echo $no2->value;
    echo $no2->valueStratosphere;
    echo $no2->valueTroposphere;
}

Sulfor Dioxide (SO2)​

$so2 = $owm->getAirPollution("SO2", "52", "13");
if ($so2 === null) {
    // No data available
} else {
    foreach ($so2->values as $data) {
        echo $data["value"];
        echo $data["value"]->getPrecision();
        echo $data["pressure"];
    }
}
