The Sunland Park City Yard NMED monitoring site recorded some high PM2.5 Thursday. At 2 pm peak PM2.5 ranged around 60 ug/m3 but PM10 was about 22 ug/m3. Maybe a instrument or calibration issue for that since we require that the PM2.5 mass be less than PM10 mass.
The EPA Air Quality Index (AQI) for the area shows some :moderate levels in southern NM.
The forecast shows a system coming in Sunday that might cause high winds and blowing dust. Will have to get an update on this on Friday.
