ASPB AND CIMSS WEEKLY HIGHLIGHTS FOR THE WEEK ENDING MAY 18, 2013

IN THE PRESS:

ITEMS FOR THE ADMINISTRATOR:

ITEMS FOR THE ASSISTANT ADMINISTRATOR:

ITEMS FOR THE OFFICE DIRECTOR, STAR:

Bill Line to be Satellite Liaison at the NOAA/National Weather Service Storm Prediction Center (SPC): Bill Line, working with Ralph Petersen, a pioneer in NearCasting, completed his M.S. work at the University of Wisconsin-Madison on the development and improvement of a NearCasting model that makes use of GOES soundings. Nearcasting is the time between nowcasting (0-1 hours) and forecasting (beyond 12 hours). He is heading to Norman, Oklahoma, where he will be the new Cooperative Institute for Mesoscale Meteorological Studies (CIMMS) Satellite Liaison at the NOAA/National Weather Service Storm Prediction Center (SPC). A story about Bill can be found at http://www.ssec.wisc.edu/news/articles/2912. (S. Ackerman, CIMSS, 608-263-3647)

ITEMS FOR THE DIVISION CHIEF, CoRP:

New Pyrocumulonimbus Blog: A new Pyrocumulonimbus (PyroCb) Blog (http://pyrocb.ssec.wisc.edu) was initiated at the Cooperative Institute for Meteorological Satellite Studies (CIMSS). This blog will serve to catalog a set of severe pyroCb events during the upcoming fire season, in an effort to begin an investigation into the effects of heavy aerosol loading (from smoke plumes) on ice clouds. For selected events CIMSS will perform detailed ice cloud retrievals and determine the influence of absorbing aerosols on subsequent ice cloud property retrievals. (B. Baum, CIMSS, 608-263-3898, S. Bachmeier, CIMSS, 608-263-3958)

Manuscript on Air Quality Impacts of California Emissions Submitted: A manuscript entitled “Impact of southern California anthropogenic emissions on ozone pollution in the mountain states” by Min Huang, Kevin W. Bowman, Gregory R. Carmichael, R. Bradley Pierce, Helen M. Worden, Ming Luo, Owen R. Cooper, Ilana B. Pollack, Thomas B. Ryerson, and Steve S. Brown was submitted to the Journal of Geophysical Research-Atmospheres. This manuscript uses the Sulfur Transport and dEposition Model (STEM) nested within the Real-time Air Quality Modeling System (RAQMS) and measurements obtained during the NOAA CalNex field mission to assess the impact of southern California anthropogenic emissions on ozone in the mountain states in May 2010. Case studies show that different scales of transport (e.g., trans-Pacific, stratospheric intrusions and inter-state) can be dynamically and chemically coupled and simultaneously affect O3 in the mountain states when the meteorology conditions are favorable (R.B. Pierce, E/RA2, 608-890-1892, brad.pierce@noaa.gov)

Figure caption: Evaluation of RAQMS/STEM-modeled O3: (a) Observed and (b) modeled monthly-mean daytime O3 at Air Quality System (AQS, circles) and Clean Air Status and Trends Network (CASTNET, triangles) sites. The model results at AQS and CASTNET sites were extracted from model at the lowest level and the levels identical to the actual altitudes of the sites, respectively. (c) NOAA WP-3D flight paths in May 2010. Black triangles denote six ozonesonde locations. (d) Box-and-whisker (minimum, 25% percentile, median, 75% percentile and maximum) plot of the observed and modeled O3 vertical profiles along all WP-3D flights in May. Green triangles denote the mean values. The data were binned vertically with a 500 m interval, and the sample sizes for each bin are shown in orange. Median vertical profiles of (e) ozonesondes (binned to model vertical layers) and (f) modeled O3 vertical profiles in May 2010 at six California locations. The numbers below the site names indicate the number of O3 profiles used at the corresponding locations.

Presentation on Image Registration: T. Schmit gave a presentation (remotely) at the Geostationary Operational Environmental Satellite (GOES)-R Summit in Newtown, PA hosted by Lockheed Martin. This presentation was part of an ‘invitation only’ splinter meeting: “On-Orbit Measurement of Image Navigation and Registration (INR) Performance”. The presentation showed the improvement in INR from the legacy to the current GOES series. More improvement, by a factor of 2, is expected from the Advanced Baseline Imager (ABI). The presentation is available at ftp://ftp.ssec.wisc.edu/ABS/GOESR_Summit/2E_INR_splinter_Schmit_GOES-R_spring_summit_2013.pptx. (T. Schmit, E/RA2, 608-263-0291, tim.j.schmit@noaa.gov)

Presentation Given on GOES-13 Imager Stray Light: Along with Cooperative Institute for Meteorological Satellite Studies (CIMSS) personnel, T. Schmit gave a presentation (remotely) on the Geostationary Operational Environmental Satellite (GOES)-13 Imager calibration issue at a meeting called by H. Bysal of Office of Satellite Products and Operations (OSPO). The presentation showed how products can be affected if stray light gets into the space look in the calibration procedure, as seems to be happening at certain times of the day. Also presented were possible remedies. Other NOAA/NESDIS and National Weather Service (NWS) personnel attended. (T. Schmit, E/RA2, 608-263-0291, tim.j.schmit@noaa.gov)
