QA band name for NO2 S5L2 Process API?

I am trying to request data using request builder. How do I get the QA band in S5L2_NO2 product? I have to put it on my Evalscript.

function setup() {

  return {

    input: ["NO2", "QA", "dataMask"],

    output: { bands:  1 , sampleType: "FLOAT32"}

  }

}

function evaluatePixel(sample) {

    if (sample.dataMask == 1 && sample.QA >= 0.75) {

        return [sample.NO2]

    } else {

        return [-9999]

    }

}

I get an error that QA band is not part of it. What is the correct name? And if there’s a document for that, please direct me.

I see from your Evalscript that you want to filter your NO2 pixels with the help of the quality parameter.

You can always check available bands and dataset-specific parameters in the Data section of our official documentation. For Sentinel-5P there is no QA band available (see Sentinel-5P documentation).

The quality filtering of Sentinel-5P pixels is performed through the minQa filter parameter that is listed in the advanced options for Sentinel-5P in the Requests Builder.
