Our Air Quality Index (AQI) forecast for the Paso del Norte is for an area of moderate. It makes sense with the current weather forecast for today.
As expected we have a low wind high PM episode in the PdN. The Sunland Park City Yard site peaked in the evening.
At the NMSU core site we see morning peak about the same time as in Sunland Park but in the evening we saw a lot less particulates.
I looked a little deeper in the OMI NO2 product image for today. Based on what I read the satellite flyover is around 13:30 local time. I plotted the RUC 21 UTC (2 pm) surface wind fields with the tropospheric NO2 and it remarkably looks reasonable. Based on the northeasterly winds I would expect the NO2 cloud to be southwest of the Paso del Norte urban area and that is pretty much is what you see below.
