Happy New Year everyone!

2012 starts off with a low wind, high PM event at the Sunland Park air quality stations. Both the SPCY and Desert View site saw high evening concentrations of PM2.5 although higher at the SPCY station.  The Airnow AQI forecast is showing green or good air quality throughout the border region on Sunday.
Below are this morning's observations at a couple NWS Cooperative weather stations.
