The representation of the TTL in a tropical channel version of the WRF model
Stephanie Evan,Stephanie Evan,Karen H. Rosenlof,Jimy Dudhia,Birgit Hassler,Birgit Hassler,Sean M. Davis,Sean M. Davis +7 more
TL;DR: In this article, the authors used the Weather Research Forecast (WRF) model to investigate key physical processes controlling the tropical Tropopause Layer (TTL) temperature and water vapor distributions in December 2005 to January-February 2006.

Journal ArticleDOI
An updated version of a gap-free monthly mean zonal mean ozone database
Birgit Hassler,Stefanie Kremser,Greg Bodeker,Jared Lewis,Kage Nesbit,Sean M. Davis,Sean M. Davis,Martyn P. Chipperfield,Sandip Dhomse,Martin Dameris +9 more
TL;DR: The BSVertOzone (Bodeker Scientific Vertical Ozone) database as discussed by the authors combines measurements from several satellite-based instruments and ozone profile measurements from the global ozonesonde network to calculate monthly mean zonal ozone.
Journal ArticleDOI
An operational tool to quality control 2D radar reflectivity data for assimilation in COSMO-DE
TL;DR: Algorithms are developed and tested to define and identify some of the most severe errors in radar data: corrupt images, low-reflectivity phenomena, which occur under special meteorological conditions, spokes, rings and clutter remnants/speckles and their application to improve data assimilation.
Journal ArticleDOI
How Robust Are Trends in the Brewer-Dobson Circulation Derived from Observed Stratospheric Temperatures?
TL;DR: This paper examined the evidence for observed trends in the stratospheric overturning circulation using a suite of currently available observational stratosphere temperature data and concluded that temperature observations do not reveal statistically significant trend in the Brewer-Dobson circulation over the per...
