We interpret a full year of high-frequency CO measurements from a tall tower in the U.S. Upper Midwest with a time-reversed Lagrangian Particle Dispersion Model (STILT LPDM) and an Eulerian chemical transport model (GEOS-Chem CTM) to develop top-down constraints on U.S. CO sources in 2009. Our best estimate is that anthropogenic CO emissions in the U.S.(More)
— The method of hidden rays is applied to the electromagnetic diffraction by composite wedges composed of perfect conductor and lossy dielectric. The E-polarized diffraction coefficients are expressed as a finite series of the cotangent functions, of which the angular period is adjusted to satisfy the edge condition at the wedge tip. The accuracy of the(More)
