      Eastward-propagating planetary waves (EPWs) were investigated prior to the boreal January 2009 major sudden stratospheric warming (SSW) event simulated by the National Center for Atmospheric Research's Whole Atmosphere ...

    • Emissions of Tetrafluoromethane (CF4) and Hexafluoroethane (C2F6) From East Asia: 2008 to 2019 

      Kim, Jooil; Thompson, Rona Louise; Park, Hyeri; Bogle, Stephanie; Mühle, Jens; Park, Mi-Kyung; Kim, Yeaseul; Harth, Christina M.; Salameh, Peter K.; Schmidt, Roland; Ottinger, Deborah; Park, Sunyoung; Weiss, Ray F. (Peer reviewed; Journal article, 2021)
      The perfluorocarbons (PFCs), tetrafluoromethane (CF4) and hexafluoroethane (C2F6), are potent greenhouse gases with very long atmospheric lifetimes. They are emitted almost entirely from industrial sources, including the ...

    • Growing Atmospheric Emissions of Sulfuryl Fluoride 

      Gressent, Alicia; Rigby, Matthew; Ganesan, Anita L.; Prinn, Ronald G.; Manning, Alistair J.; Mühle, Jens; Salameh, Peter K.; Krummel, Paul; Fraser, Paul J.; Steele, Paul; Mitrevski, Blagoj; Weiss, Ray F.; Harth, Christina M.; Wang, Ray H.; O'Doherty, S.; Young, Dickon; Park, Sunyoung; Li, S.; Yao, Bo; Reimann, Stefan; Vollmer, Martin K.; Maione, Michela; Arduini, Jgor; Lunder, Chris Rene (Peer reviewed; Journal article, 2021)
      The potent greenhouse gas sulfuryl fluoride (SO2F2) is increasingly used as a fumigant, replacing methyl bromide, whose structural and soil fumigation uses have been phased out under the Montreal Protocol. We use measurements ...

    • How Atmospheric Chemistry and Transport Drive Surface Variability of N2O and CFC-11 

      Ruiz, Daniel J.; Prather, Michael J.; Strahan, Susan E.; Thompson, Rona Louise; Froidevaux, Lucien; Steenrod, Stephen D. (Peer reviewed; Journal article, 2021)
      Nitrous oxide (N2O) is a long-lived greenhouse gas that affects atmospheric chemistry and climate. In this work, we use satellite measurements of N2O, ozone (O3), and temperature from the Aura Microwave Limb Sounder (MLS) ...

    • Impact of Snow Initialization in Subseasonal‐to‐Seasonal Winter Forecasts With the Norwegian Climate Prediction Model 

      Li, Fei; Orsolini, Yvan; Keenlyside, Noel; Shen, Mao-Lin; Counillon, Francois; Wang, Yiguo (Journal article; Peer reviewed, 2019)
      Snow initialization has been previously investigated as a potential source of predictability atthe subseasonal‐to‐seasonal (S2S) timescale in winter and spring, through its local radiative,thermodynamical, and hydrological ...

    • A Precipitation Isotopic Response in 2014–2015 to Moisture Transport Changes in the Central Himalayas 

      Axelsson, Josefine; Gao, Jing; Eckhardt, Sabine; Cassiani, Massimo; Cheng, Deliang; Zhang, Qiong (Peer reviewed; Journal article, 2023)
      The impact of moisture transport and sources on precipitation stable isotopes (δ18O and d-excess) in the central Himalayas are crucial to understanding the climatic archives. However, this is still unclear due to the lack ...

    • Seasonal Variation of Wet Deposition of Black Carbon at Ny-Ålesund, Svalbard
