Overview of the NASA Solar Irradiance Science Team (SIST) Program Special Section
Autor: Matthew T. DeLand, Greg Kopp, David B. Considine
Publikováno v: Earth and Space Science, Vol 6, Iss 12, Pp 2229-2231 (2019)
Abstract Solar irradiance represents the dominant energy source heating the Earth's atmosphere and climate. Both total solar irradiance and spectral solar irradiance vary over the 11‐year solar cycle. Characterizing these variations with sufficient

Processes controlling the seasonal variations of 210Pb and 7Be at the Mt. Cimone WMO-GAW global station, Italy: A model analysis
Autor: Erika Brattich, Hongyu Liu, Laura Tositti, David B. Considine, James H. Crawford
We apply the Global Modeling Initiative (GMI) chemistry and transport model driven by the NASA’s MERRA assimilated meteorological data to simulate the seasonal variations of two radionuclide aerosol tracers (terrigenous 210Pb and cosmogenic 7Be) at

Sensitivity of tracers and a stratospheric aircraft perturbation to two-dimensional model transport variations
Autor: Richard S. Stolarski, Eric L. Fleming, Charles H. Jackman, David B. Considine
Publikováno v: Journal of Geophysical Research: Atmospheres. 106:14245-14263
We examine the sensitivity of two-dimensional model simulations of stratospheric tracers to uncertainties in the model transport and explore how such uncertainties impact the simulation of a lower stratospheric perturbation due to high-speed civil tr

Is upper stratospheric chlorine decreasing as expected?
Autor: Darryn W. Waugh, David B. Considine, Eric L. Fleming
Publikováno v: Geophysical Research Letters. 28:1187-1190
The monthly-mean total chlorine abundance (Cl T ) at 55 km inferred from HALOE HCl observations increases from 1992 to 1997 and then subsequently decreases. The pre-1997 increase is consistent with surface measurements of Cl T time-lagged by around 6

Simulation of stratospheric tracers using an improved empirically based two-dimensional model transport formulation
Autor: Charles H. Jackman, Richard S. Stolarski, Eric L. Fleming, David B. Considine
Publikováno v: Journal of Geophysical Research: Atmospheres. 104:23911-23934
We have developed a new empirically based transport formulation for use in our Goddard Space Flight Center (GSFC) two-dimensional chemistry and transport model. In this formulation, we consider much of the information about atmospheric transport proc

The influence of solar proton events on the ozone layer
Autor: David B. Considine, Charles H. Jackman, Eric L. Fleming, Francis M. Vitt
Publikováno v: Advances in Space Research. 24:625-630
Our two-dimensional chemistry and transport atmospheric model was used to simulate the influence of solar proton events (SPEs) over the 1965 to 1995 time period. Extremely large particle events with huge fluxes of very high energy protons occurred in
