May 19

Nice sunny and uneventful air quality day. Some wind in the afternoon but not enough for dust. See this afternoon's MODIS Aqua true-color image. Northern NM had some cloud cover but very little near the border.

I didn't see any nearby fires or smoke plumes from the NOAA HMS mapping today.

Looking at MODIS AOD from the morning Terra (top) and comparing it to the afternoon Aqua (bottom), we see interesting differences mainly along the Rio Grande River Valley. AOD is higher in the morning and low in the afternoon.





There is an interesting news article about the dust problem on I-40 in Arizona. It is a big problem and ADOT is attempting to fix it. We'll see what they end up doing. I do know that the area surrounding the dust source has not seen rain for quite a while.
