ARL Weekly News – December 6, 2019
Dr. Howard Diamond will reprise his role as the lead editor for the Tropics Chapter for the annual State of the Climate Report for 2019; the process to begin that effort was begun with a kickoff call for all chapter editors on December 3rd, followed up with an e-mail to all authors for the Tropics Chapter to get their inputs turned in by January 23, 2020. This will be Dr. Diamond’s 15th edition of the Tropics Chapter as the lead editor, dating back to the State of the Climate Report for 2005. Over that period, the chapter has grown considerably in size and added a number of new authors; the topics range from a discussion of the status of the El Niño Southern Oscillation, to the Madden-Julian Oscillation, Indian Ocean Dipole, Ocean Heat Content, and Intertropical Convergence Zones in the Atlantic and Pacific, to detailed descriptions of global tropical cyclone activity in 7 distinct ocean basins. There are 25 authors from 5 countries that are responsible for providing the content for the chapter. The annual State of the Climate Report is published as a supplement to the Bulletin of the American Meteorological Society, and past reports can be found at the following link
“Using Short-Term CO/CO2 Ratios to Assess Air Mass Differences over the Korean Peninsula during KORUS-AQ,” co-authored by Xinrong Ren, was published in the October 2019 issue of Journal of Geophysical Research: Atmospheres. It is available at agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2018JD029697.
Rick Saylor visited the U. S. Environmental Protection Agency’s (U.S. EPA) Center for Environmental Measurement & Modeling in Research Triangle Park, North Carolina, on Dec. 4-5. On Dec. 4, Dr. Saylor presented a research seminar entitled “Dynamic NH3 Exchange within a Deciduous Forest Canopy in the Southern Appalachians” that described recent model results for an EPA-NOAA collaboration investigating ammonia deposition and emissions in and above a deciduous forest in western North Carolina. On Dec. 5, Dr. Saylor presented another seminar entitled “The NOAA UFS Global Aerosol and Atmospheric Composition Model: Description, Evaluation and Future Directions” as part of the U.S. EPA’s New Insights in Atmospheric Science Seminar Series. This seminar described recent efforts in NOAA to create a new global aerosol and atmospheric composition model within the Unified Forecast System. The seminar highlighted the work done by ARL to implement a new dust emission algorithm in the global model, in collaboration with the Global Systems Division and the Chemical Sciences Division of the Earth System Research Laboratory in Boulder, Colorado.
