April 23 and 24 summaries

April 23

A breezy day over our monitoring stations but not enough wind for widespread wind erosion. Below are RUC winds at 6 pm showing a pulse of high winds across the Bootheel region but not much elsewhere.


April 24

A windy day and high particulate concentrations were observed at a few of the long term monitoring sites in the region. Below are RUC winds at 22 UTC (4 pm MDT).

A sampling of PM10 concentrations around the network shows that the highest values occurred at the Sunland Park City Yard.
Smoke plumes were transported toward the east-northeast today from the winds. Only a couple of wildfires were burning near our region today. Below is the MODIS-Terra image with the NOAA HMS fire detections and smoke outlines.
By the end of the day the Abrams fire burned about 5,000 acres and was 40 percent contained. I was at Aguirre Springs in the afternoon and saw the smoke from there. Between the windblown dust and fire the Tularosa basin was hazy today.

The AQI outlook for Monday shows moderate air quality over the Paso del Norte but good elsewhere.
Our next chance for a larger widespread dust event is Tuesday. Below is the GFS wind forecast for Tuesday afternoon. Most of the winds looks to be northeast of us but we'll be getting high winds as well.
