  • Variability of fire emissions on interannual to multi-decadal timescales in two Earth System models

    Open AccessD S Ward, Elena Shevliakova et al.ARTICLEEnvironmental Research Letters2016

    Connections between wildfires and modes of variability in climate are sought as a means for predicting fire activity on interannual to multi-decadal timescales. Several fire drivers, such as temperature and local drought index, have been shown to vary on these timescales, and analysis of tree-ring data suggests covariance between fires and climate oscillation indices in some regions. However, the shortness of the satellite record of global fire e…

  • The Community Earth System Model (Cesm) Large Ensemble Project

    Open AccessJennifer E Kay, Clara Deser et al.ARTICLEBulletin of the American…2015

    While internal climate variability is known to affect climate projections, its influence is often underappreciated and confused with model error. Why? In general, modeling centers contribute a small number of realizations to international climate model assessments [e.g., phase 5 of the Coupled Model Intercomparison Project (CMIP5)]. As a result, model error and internal climate variability are difficult, and at times impossible, to disentangle. I…

  • Global distribution and trends of tropospheric ozone

    Open AccessOwen R Cooper, D D Parrish et al.ARTICLEElementa Science of the…2014

    Tropospheric ozone plays a major role in Earth’s atmospheric chemistry processes and also acts as an air pollutant and greenhouse gas. Due to its short lifetime, and dependence on sunlight and precursor emissions from natural and anthropogenic sources, tropospheric ozone’s abundance is highly variable in space and time on seasonal, interannual and decadal time-scales. Recent, and sometimes rapid, changes in observed ozone mixing ratios and ozone …

  • The Community Earth System Model

    James W Hurrell, M M Holland et al.ARTICLEBulletin of the American…2013

    By simulating biogeochemical cycles, the Greenland ice sheet, and more-with reach to the lower thermosphere-this system gives the research community a flexible, state-of-thescience tool for understanding climate variability and change.

  • Changes in the frequency and return level of high ozone pollution events over the eastern United States following emission controls

    Open AccessHarald E Rieder, Arlene M Fiore et al.ARTICLEEnvironmental Research Letters2013

    In order to quantify the impact of recent efforts to abate surface ozone (O3) pollution, we analyze changes in the frequency and return level of summertime (JJA) high surface O3 events over the eastern United States (US) from 1988–1998 to 1999–2009. We apply methods from extreme value theory (EVT) to maximum daily 8-hour average ozone (MDA8 O3) observed by the Clean Air Status and Trends Network (CASTNet) and define O3 extremes as days on which M…

  • Projected changes of extreme weather events in the eastern United States based on a high resolution climate modeling system

    Open AccessYang Gao, Joshua S Fu et al.ARTICLEEnvironmental Research Letters2012

    This study is the first evaluation of dynamical downscaling using the Weather Research and Forecasting (WRF) Model on a 4 km × 4 km high resolution scale in the eastern US driven by the new Community Earth System Model version 1.0 (CESM v1.0). First we examined the global and regional climate model results, and corrected an inconsistency in skin temperature during the downscaling process by modifying the land/sea mask. In comparison with observat…

  • The RCP greenhouse gas concentrations and their extensions from 1765 to 2300

    Open AccessMalte Meinshausen, Steven J Smith et al.ARTICLEClimatic Change2011

    We present the greenhouse gas concentrations for the Representative Concentration Pathways (RCPs) and their extensions beyond 2100, the Extended Concentration Pathways (ECPs). These projections include all major anthropogenic greenhouse gases and are a result of a multi-year effort to produce new scenarios for climate change research. We combine a suite of atmospheric concentration observations and emissions estimates for greenhouse gases (GHGs) …

  • Historical (1850–2000) gridded anthropogenic and biomass burning emissions of reactive gases and aerosols

    Open AccessJean‐François Lamarque, J-F Lamarque et al.ARTICLEAtmospheric Chemistry and Physics2010

    We present and discuss a new dataset of gridded emissions covering the historical period (1850–2000) in decadal increments at a horizontal resolution of 0.5° in latitude and longitude. The primary purpose of this inventory is to provide consistent gridded emissions of reactive gases and aerosols for use in chemistry model simulations needed by climate models for the Climate Model Intercomparison Program #5 (CMIP5) in support of the Intergovernmen…
