Finding X and Y coordinates for Air Quality Data

[KathrynSie]

I retrieved an air quality dataset on a state website. Unfortunately, I cannot map it on ArcGIS Pro via IDW. The dataset has no x and y coordinates. Is there a way I can get x and y coordinates on ArcGIS? I tried these steps:

1. 

2. Add the dataset and go to Geocode Table

3. Choose ArcGIS World Geocoding Service

4. Choose "more than one field"

5. Then I am stucked. The dataset I used does not have any of these information.

6. These are the variables in my dataset. There is no way for me to contact anyone in the state website. Can anyone help me?

I think you need another dataset with XY coordinates or points where this information was taken.

This dataset was download from NYC Data website. They provide no way to contact them to get x y coordinates
