RISA Trend Analysis of the 1930–2010 Extreme Heat Events in the Continental United States
Publisher: American Meteorological Society
Abstract: xtreme heat events (EHEs) are linked to mortality rates, making them an important research subject in both the climate and public health fields. This study evaluated linear trends in EHEs using the U.S. Historical Climatology ...
An Object-Based Approach for Quantification of GCM Biases of the Simulation of Orographic Precipitation. Part I: Idealized Simulations
Publisher: American Meteorological Society
Abstract: n object-based evaluation method to quantify biases of general circulation models (GCMs) is introduced using the National Center of Atmospheric Research (NCAR) Community Atmosphere Model (CAM). Idealized experiments with ...
Assimilating TOVS Humidity into the GEOS-2 Data Assimilation System
Publisher: American Meteorological Society
Abstract: The humidity data retrieved from the TIROS Operational Vertical Sounder (TOVS) measurements is assimilated into the Goddard Earth Observing System (GEOS) data assimilation system. The study focuses on the impact of the ...
Multidimensional Flux-Form Semi-Lagrangian Transport Schemes
Publisher: American Meteorological Society
Abstract: An algorithm for extending one-dimensional, forward-in-time, upstream-biased, flux-form transport schemes (e.g., the van Leer scheme and the piecewise parabolic method) to multidimensions is proposed. A method is also ...
An Object-Based Approach for Quantification of GCM Biases of the Simulation of Orographic Precipitation. Part II: Quantitative Analysis
Publisher: American Meteorological Society
Abstract: n object-based evaluation method is applied to the simulated orographic precipitation for the idealized experimental setups using the National Center of Atmospheric Research (NCAR) Community Atmosphere Model (CAM) with the ...
Thermodynamic Balance of Three-Dimensional Stratospheric Winds Derived from a Data Assimilation Procedure
Publisher: American Meteorological Society
Abstract: The NASA/Goddard three-dimensional chemistry and transport model is driven by winds from a stratospheric data assimilation system. Synoptic- and planetary-scale patterns, apparent in satellite observations of trace ...
A Comparison of Winds from the STRATAN Data Assimilation System to Balanced Wind Estimates
Publisher: American Meteorological Society
Abstract: Winds derived from a stratospheric and tropospheric data assimilation system (STRATAN) are compared with balance winds derived from National Meteorological Center/Climate Analysis Center (NMC/CAC) heights. At middle latitudes ...
Lamination Frequencies as a Diagnostic for Horizontal Mixing in a 3D Transport Model
Publisher: American Meteorological Society
Abstract: Ozone simulations are performed in an attempt to simulate laminar events with the frequency observed in balloon ozone sondes. The winds are taken from the Goddard Earth Observing System Data Assimilation System (GEOS DAS); ...
An Assimilated Dataset for Earth Science Applications
Publisher: American Meteorological Society
Abstract: The Data Assimilation Office at NASA's Goddard Space Flight Center is currently producing a multiyear gridded global atmospheric dataset for use in climate research, including tropospheric chemistry applications. The data, ...
Assessing Tracer Transport Algorithms and the Impact of Vertical Resolution in a Finite-Volume Dynamical Core
Publisher: American Meteorological Society
Abstract: odeling the transport of trace gases is an essential part of any atmospheric model. The tracer transport scheme in the Community Atmosphere Model finite-volume dynamical core (CAM-FV), which is part of the National Center ...
