Discovery

Nurture Intellectual Infrastructure for Scientific and Engineering Research

EOL scientists and engineers make new discoveries and developments that push the boundaries of observational and measurement science. Much of that is achieved through a vigorous set of internal and external collaborations and partnerships. Given a broad scope of its scientific and engineering activities, unique educational and training opportunities for the next generation of observational scientists and engineers lie in EOL. Our field campaigns provide opportunities to inform and excite the public worldwide about the importance of observational research and understanding the natural environment in which we all live. Imperative 4 is multifaceted and encompasses the following activities: 1) scientific and engineering research within EOL and in collaboration with our user community; 2) internships, new user training, and other educational efforts; and 3) outreach. 

 

Foster Scientific and Engineering Research in EOL

WMO Award

WMO logoHolger Vömel traveled to Madrid, Spain in September 2017 to attend the World Meteorological Organization (WMO) Commission for Instruments and Methods of Observations (CIMO) Technical Conference, during which he received the WMO Award for Outstanding Research Paper on Instrument and Methods of Observations.  Established in 1985, this is a very prestigious award.  The awarded paper has had a significant impact on the WMO operational community. The winning paper titled “Reference quality upper-air measurements: GRUAN data processing for the Vaisala RS92 radiosonde” was published in the Atmospheric Measurement Techniques in December 2014.

AMS Editor's Award

Scott Ellis was among the 2017 American Meteorological Society (AMS) award recipients. Scott received the Editor’s Award from the Journal of Applied Meteorology and Climatology and was lauded for his “consistently excellent reviews.” 

WMO Appointment

Mike Dixon (RSF) was recently appointed to the WMO Commission for Instruments and Methods of Observation (CIMO) Inter-Programme Expert Team on Operational Weather Radars (IPET-OWR).  This appointment gives NCAR opportunities to help make policy decisions with respect to software and data formats and to help out member states who do not have resources to develop software on their own.

NEXRAD Technical Advisory Committee (TAC)

Tammy Weckwerth was named to the NEXRAD Technical Advisory Committee (TAC). The purpose of the TAC is to assess the scientific merit of relevant research and development activities and to advise on the future direction and further analyses that should be performed to get that research or those products to a level to be considered for implementation on the national radar network.The link between the NEXRAD program and EOL’s S-Pol is strong because the programs are synergistic and complementary. The NEXRAD program supports some critical S-Pol hardware components and some S-Pol research activities while S-Pol research activities help improve the NEXRAD data quality.

Support Outreach 

Cheyenne Frontier Days Outreach Event

NSF approved a request by EOL to display the NSF/NCAR C-130 and the University of Wyoming King Air aircraft as well as one Center for Severe Weather Research (CSWR) Doppler on Wheels during the 2017 Cheyenne Frontier Days. This request was prompted by UCAR President’s desire to celebrate UCAR/NCAR partnership with organizations in Wyoming as part of Cheyenne’s 150th Anniversary celebration. The static display of these facilities will be part of a larger display of aircraft at the U.S. Air National Guard side of the Cheyenne Regional Airport.  The event is scheduled for 26 July and concurrent with the annual air show featuring the USAF Thunderbirds Air Demonstration Squadron. Several staff from UCAR’s President’s Office, NCAR/CISL, NCAR/EOL, the University of Wyoming, and the CSWR will be tasked to interact with the public and answering questions. In addition to showcasing NSF’s Lower Atmosphere Observing Facilities, we want to raise awareness that Wyoming and Colorado are hubs of atmospheric research and emphasize the role of NSF in enabling those activities. Based on past visitor numbers, it is anticipated that the static display could reach as many as 2,000 people during the one-day event.

Per request by the UCAR President’s Office, EOL displayed the NSF/NCAR C-130 on 26 July during the 2017 Cheyenne Frontier Days. The static display was part of a larger display of aircraft at the Wyoming Air National Guard side of the Cheyenne Regional Airport. In addition to showcasing one of NSF’s premier Lower Atmosphere Observing Facilities, the display also included the University of Wyoming King Air and one of the Doppler on Wheels managed and operated by the Center of Severe Weather Research (CSWR). Twenty-two staff from EOL, UWY, CSWR, and CISL interacted with the public and answered a range of questions related to these facilities and the research that is routinely carried out by these airborne and ground-based platforms. One of the main goals of our participation was to raise awareness that Wyoming and Colorado are hubs of atmospheric research and to emphasize the role of the National Science Foundation in enabling those activities. We estimated that staff interacted with as many as 2,220 people during this one-day event. 

ARTSE

Atmospheric Response to a Total Solar Eclipse (ARSTE), an educational deployment of two ISFS towers, was recently approved by NSF to observe the solar eclipse in Grand Island, Nebraska. ARSTE is lead by Dr. Scott Gunter of Columbus State University in Columbus, Georgia.

On ground, ISFS supported the ARTSE educational deployment, allocated to Dr. William Gunter from Columbus State University from 18 to 23 August 2017. Two ISFS stations were deployed to Grand Island, Nebraska as part of an undergraduate class called “Meteorology of the Solar Eclipse”, which focused on the link between the sun and atmospheric processes. One of the stations was installed at Stuhr Museum as part of the “Gem Over the Prairie Eclipse Event” to provide additional information to the public and attracted close to 5,000 people during the event.
