Differences in Ice Cloud Optical Depth from CALIPSO and Ground-Based Raman Lidar at the ARM SGP and TWP Sites
Balmes, Kelly AnnIce cloud column optical depths from the Cloud-Aerosol Lidar and Infrared Pathfinder Satel- lite Observations (CALIPSO) satellite and ground-based Raman lidars (RLs) at the Atmo- spheric Radiation Measurement (ARM) Southern ... -
Diurnal Cycles of Synthetic Microwave Sounding Lower-Stratospheric Temperatures from Radio Occultation Observations, Reanalysis, and Model Simulations
Sweeney, AodhanAn observationally-based global climatology of the temperature diurnal cycle in the lower stratosphere is derived from eleven different satellites with Global Positioning System-Radio Occultation (GPS-RO) measurements from ... -
Effect of snow grain shape and impurities on snow albedo and its parameterization: China, North America, and the Arctic
Dang, ChengSnow cover is important for Earth’s surface energy budget, primarily because the surface reflectance (albedo) is greatly increased if covered by a layer of snow. A correct estimation of snow albedo is therefore crucial for ... -
Observations of tropical cirrus by elastic backscatter lidars and the development of a cloud and aerosol retrieval algorithm for Raman lidars
Thorsen, TylerTropical cirrus cloud properties from elastic backscatter lidars--- namely the Atmospheric Radiation Measurement (ARM) program's ground-based micropulse lidars (MPL) and the spaceborne Cloud-Aerosol Lidar Infrared Pathfinder ... -
On the structure of atmospheric warming in models and observations: Implications for the lapse rate feedback
Po-Chedley, StephenThis dissertation investigates the structure of atmospheric warming in observations and general circulation models (GCMs). Theory and GCMs suggest that warming is amplified in the tropical upper troposphere relative to the ... -
Reconciling tropospheric temperature trends from the microwave sounding unit
Po-Chedley, Stephen (2012-09-13)The University of Alabama at Huntsville (UAH), Remote Sensing Systems (RSS), and the National Oceanic and Atmospheric Administration (NOAA) have constructed long-term temperature records for deep atmospheric layers using ... -
Retrievals of Drizzle and Cloud Liquid Water Contents in Stratocumulus and Implications for Subgrid-scale Impacts on Model Autoconversion and Accretion Rates
Zhao, WeiMarine stratocumulus clouds (Sc) cover large areas of the Earth and have a substantial impact on the Earth’s radiative balance by reflecting copious amounts of sunlight away from the Earth and emitting longwave radiation ... -
The Aerosol Direct Radiative Effect at the ARM SGP and TWP Sites
Balmes, Kelly AnnThe clear-sky aerosol direct radiative effect was estimated at the Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) site in Lamont, Oklahoma and Tropical Western Pacific (TWP) site in Darwin, Australia. ... -
The Diurnal Cycle of Clouds and Precipitation at the ARM SGP Site
Zhao, WeiMillimeter Wavelength Cloud Radar (MMCR) data from Dec. 1996 to Dec. 2010, collected at the U. S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) program Southern Great Plains (SGP) site are used to ... -
The Effect of Hydrometeors on MSU/AMSU Temperature Observations over the Tropical Ocean
Alizadeh Pahlavan, HamidThe temperature of Earth’s atmosphere has been monitored continuously since late 1978 by the Microwave Sounding Unit (MSU) and the Advanced Microwave Sounding Unit (AMSU) flown on polar-orbiting weather satellites. It is ... -
The QBO Dynamics and Gravity Waves Characteristics as Seen in ERA5 Reanalysis
Alizadeh Pahlavan, HamidThe quasi-biennial oscillation (QBO) is the primary mode of interannual variability in the tropical stratosphere. It is characterized by the downward propagation of successive westerly and easterly wind regimes with an ... -
Tropical tropopause layer cirrus and its relation to tropopause
Tseng, Hsiu-HuiThis study examines the spatial and temporal patterns of tropical tropopause layer (TTL) cirrus clouds (i.e., clouds with bases higher than 14.5 km) and their relationship to tropical tropopause including both cold point ... -
Understanding changes in the stratospheric circulation from observations and simulations
Lin, Pu (2013-07-23)This study investigates the variation of the Brewer-Dobson circulation (BDC) in the stratosphere on interannual and decadal timescales from both observations and numerical simulations. Lower stratospheric temperature has ...
