A different pattern for the Anthony Elementary site but we see a morning and evening peak in particulates. It is important to note that peak PM10 is higher here than at Sunland Park. Peak hourly PM10 was 275 µg/m3 at 6 pm. Peak PM2.5 was 39 µg/m3 at the same time.
The Las Cruces west mesa site showed a ramp-up of PM10 as well but not as striking as in Sunland Park
This evening's Air Quality Index (AQI) showed moderate levels in south-central New Mexico and west El Paso County. This pretty much matches what we see in the NMED monitoring.
The aloft haze layer is not visible in tonight's 1 am sky compared to this past weekend. Still lots of light scattering in this image. This view is looking toward the southwest overlooking Las Cruces.
The past day's AQI animation shows this event picking up in the evening around 8 pm MST.
Tomorrow's AQI doesn't show the moderate area in our area.
