Lindsey, D. T., received a NASA Agency Honor Award Outstanding Leadership Medal. This NASA medal “is awarded to government employees for notable leadership accomplishments that have significantly influenced the NASA Mission.”

Lindsey, D. T., K. Mozer, and M. Seybold received the GOES-R Program Outstanding Communications Award for the period Oct-Dec 2018, primarily for their work in spreading information about the GOES-17 ABI anomaly to external users.

Knaff, J. A., received an appreciation certificate from AMS publications for reviewing 14 manuscripts for Monthly Weather Review and Weather and Forecasting. The certificate is shown below.


Aerospace Visitors: Dave Lubar and Mike Jamilkowski from Aerospace visited CIRA on 25 June 2019 to meet with Dan Lindsey about an ABI value assessment. (D. Lindsey)


Korean visitors: Prof. Sung Hyun Nam and his student Seung-Woo Lee of College of Natural Sciences, Seoul National University met with several individuals at CIRA to discuss their work. This has been a multi-year collaboration with Dr. Nam having made several visits in the last four years. Topics discussed were: tropical cyclone wind estimation applications and satellite detection of natural hazards, ocean properties and atmospheric compositions. (J. Knaff, L. Grasso, Y.-J. Noh)


Visitor from ECMWF: Louie Grasso and Ting-Chi Wu spent time with Richard Forbes, who is visiting Atmospheric Science Professor Christine Chiu from the European Centre for Medium-Range Weather Forecasts (ECMWF) on June 20. They discussed numerical modeling, microphysics, radiative transfer, and data assimilation. (L. Grasso and T.-C. Wu)


FSU Visitor: Justin Stow- Florida State University. 28 May- 2 August, TC group, ( C. Slocum)


StAR Director Visit: Harry Cikanek, NESDIS Satellite Applications and Research (StAR) Director, visited the Regional and Mesoscale Meteorology Branch (RAMMB) on 22 May 2019, as part of his travel to attend the CIRA Fellow’s meeting the following day. A 3-hour meeting was arranged with the RAMMB feds only, to discuss RAMMB/StAR interactions in particular. Afterward, some of the RAMMB had dinner with Harry at a local restaurant. (D. Hillger, D. Molenar, J. Knaff, D. Lindsey)


GINA Director Visit: John Pace, Director of the Geographic Information Network of Alaska (GINA), part of the University of Alaska-Fairbanks, visited CIRA on 20 May 2019 to discuss collaboration opportunities. CIRA researchers involved with Alaska-region research met with Mr. Pace to discuss ongoing JPSS-PGRR research activities at CIRA that may be of relevance to GINA’s activities. GINA’s primary mission is to provide near real-time operational products and services for Alaska weather forecasting and to provide geospatial development and analysis services to the University of Alaska system and the state of Alaska that support education, research, and operations in service to the public. (S. Miller, R. Brummer, C. Seaman, J. Dostalek and Y.-J. Noh)


HFIP funding: Dr. Evan Kalina, CIRES/CU-Boulder and NOAA/ESRL, visited CIRA to collaborate on a currently-funded HFIP project entitled, “Enabling Cloud Condensate Cycling via All-Sky Radiance Assimilation in HWRF.” As part of the visit, he discussed NOAA’s investigation of removing Vortex Initialization (VI) from the HWRF. Dr. Kalina went over his new HWRF branch which replaces VI and gave a seminar entitled, “Fostering Community Innovation in the Hurricane Weather Research and Forecast System.” (T.-C. Wu, L. Grasso, M. Zupanski)


ONR Visitor: Josh Cossuth, ONR assistant program manager, visited the tropical cyclone group to discuss priorities for FY2020 operational transition and maintenance funding. ONR has tentatively agreed to fund work on updating several operational forecast tools and the transition of existing tools to JTWC. Conversations also discussed the current ONR rapid intensification funding call and the installation of a software kit at NHC. (J. Knaff, K. Musgrave, C. Slocum)


HRD Visitor: Joe Cione, Hurricane Research Division, paid a visit to CIRA’s tropical cyclone group to discuss what HRD is doing with unmanned aircraft and how CIRA/RAMMB can get more involved. We also picked Joe’s mind on how to reprocess NCODA ocean analyses to better address under-eyewall ocean cooling. (J. Knaff, K. Musgrave, C. Slocum)


GOES Program Office Visitors: On 29 April 2019, Pam Sullivan and Alexander Krimchansky from the GOES-R Program Office, and Mike Clark from OMB visited CIRA. The primary purpose of the visit was to get an update on the ongoing GOES-R-funded research projects. (D. Lindsey, S. Miller and R. Brummer)
