A multidecadal study of cirrus in the tropical tropopause layer
Listed in National Center for Atmospheric Research
Changes in the distributions of cirrus in the upper troposphere centered at 100âhPa in the tropical tropopause layer (TTL) during the last 27âyears (1985-2012) are quantified based upon an analysis of five independent data sets.
Description
Stratospheric Aerosol and Gas Experiment II, Halogen Occultation Experiment, Cryogenic Limb Array Etalon Spectrometer, High Resolution Dynamics Limb Sounder, and Cloud-Aerosol Lidar with Orthogonal Polarization data are used to determine cirrus frequency-of-occurrence geospatial distributions in the TTL in multiple year segments during 1985â2012.
Full width at half maximum (FWHM) tropical widths of cirrus zonal averages of occurrence frequency centered at 100âhPa are calculated for each experiment. The FWHMs have a 2Ï trend of 0.28â±â1.5° decadeâ»Â¹1. This statistically insignificant trend is similar to those calculated by Davis and Rosenlof (2012) based upon analyses of reanalysis tropopause height and tropopause latitudinal gradients near 100âhPa.
