RISThe Area of the Stratospheric Polar Vortex as a Diagnostic for Tracer Transport on an Isentropic Surface
Publisher: American Meteorological Society
Abstract: Data retrieved from the LIMS (Limb lnfrared Monitor of the Stratosphere) experiment are used 10 calculate daily isentropic distributions of Ertel's potential vorticity, ozone, water vapor and nitric acid at the 850 K level ...
Stability of the Surface Layer and Its Relation to the Dispersion of Primary Pollutants in St. Louis
Publisher: American Meteorological Society
Abstract: The role of atmospheric stability in the lowest 30 m in characterizing the dispersion of the primary pollutants CO, NO and hydrocarbons is investigated using the 1976 air quality data set for St. Louis. Stability is ...
Estimation of Synoptic Fields of Middle Atmosphere Parameters from Nimbus-7 LIMS Profile Data
Publisher: American Meteorological Society
Abstract: The most widely used version of the Nimbus-7 LIMS middle atmosphere dataset is the set of high quality, daily, and zonal Fourier coefficients that resolve information out to six wavenumbers at 12 UTC. A Kalman filter ...
Implications of the Stratospheric Water Vapor Distribution as Determined from the Nimbus 7 LIMS Experiment
Publisher: American Meteorological Society
Abstract: The LIMS experiment on Nimbus 7 has provided new results on the stratospheric water vapor distribution. The data show 1) a latitudinal gradient with mixing ratios that increase by a factor of 2 from equator to ±60 degrees ...
The SPARC Intercomparison of Middle-Atmosphere Climatologies
Publisher: American Meteorological Society
Abstract: An updated assessment of uncertainties in ?observed? climatological winds and temperatures in the middle atmosphere (over altitudes ?10?80 km) is provided by detailed intercomparisons of contemporary and historic datasets. ...
