Nov. 21 - A passing cold front over the region today is generating wind blown dust at areas not receiving precipitation. The two plots below show the peak winds at the Sunland Park City Yard station starting in the morning and lasting throughout the afternoon and the plot below that shows the hourly PM10 and PM2.5 concentrations.

Temperatures were mild this morning with the low at the Las Cruces Airport at 43F and 41 at the Deming airport. Our low at NMSU was 44F this morning. At 10:15 am the Las Cruces Airport AWOS measured west winds at 26 mph with gusts to 49 mph. Overcast skies over Las Cruces also yielded some showers this  morning.
We were fortunate to receive some precipitation today as seen from the radar. Below shows the precipitation patterns across the region as of 3:03 pm with a few areas potentially getting up to 0.5 inch north of Deming.
A generous donation from the New Mexico Environment Department Air Quality Bureau has provided four used high volume particulate samplers to the Environmental Sciences Department at NMSU. Appreciation goes out to the staff at NMED AQB and Michael Baca for delivering the instruments to us. These are PM10 Wedding samplers that collect aerosols on 8x10 inch filters.
