Manuscript on Impact of Stratospheric Intrusions Published: A manuscript entitled "An overview of the 2013 Las Vegas Ozone Study (LVOS): Impact of stratospheric intrusions and long-range transport on surface air quality" by A.O. Langford, C.J. Senff, R.J. Alvarez II, J. Brioude, O.R. Cooper, J.S. Holloway, M.Y. Lin, R.D. Marchbanks, R.B. Pierce, S.P. Sandberg, A.M. Weickmann, and E.J. Williams was published in Atmospheric Environment. The manuscript focuses on the seasonal contribution of stratosphere-to-troposphere transport (STT) and long-range transport to surface ozone in Clark County, Nevada and shows that STT can directly contribute to exceedances of the National Ambient Air Quality Standard (NAAQS) in this area. The primary instrument used during LVOS was the TOPAZ (Tunable optical profiler for aerosols and ozone) 3-wavelength mobile differential absorption lidar (DIAL) system, which can profile ozone and aerosol layers from near the surface to ~2.5 km above ground level. The Real-time Air Quality Modeling System (RAQMS) provided daily forecasts of STT and long-range transport during LVOS (R.B. Pierce, E/RA2, 608-890-1892, brad.pierce@noaa.gov)

CIMSS VISIT Activities: On April 16, 2015 S. Lindstrom participated in a Virtual Institute for Satellite Integration Training (VISIT) Satellite Chat session, which discussed the variety of weather impacts associated with a strong western US trough of low pressure (http://rammb.cira.colostate.edu/training/visit/satellite_chat/20150416/). In addition, the Cooperative Institute for Meteorological Satellite Studies (CIMSS) Satellite Blog was updated with a post highlighting the strong dust storm affecting parts of southern Nevada and southern California on April 14, 2015 (http://cimss.ssec.wisc.edu/goes/blog/archives/18139). (S. Bachmeier, CIMSS, 608-263-3958, S. Lindstrom, CIMSS, 608-263-4425)
