RISOzone Destruction in Continental Stratus Clouds: An Aircraft Case Study
Publisher: American Meteorological Society
Abstract: Apparent depletion of ozone in a cold (?0°C), continental stratus cloud system was observed during in situ data collection on 30 April 1994 at the Department of Energy Clouds and Radiation Test Bed site in northern Oklahoma. ...
Cirrus Cloud Microphysical Property Retrieval Using Lidar and Radar Measurements. Part I: Algorithm Description and Comparison with In Situ Data
Publisher: American Meteorological Society
Abstract: A retrieval algorithm is described to estimate vertical profiles of cirrus-cloud ice water content (IWC) and general effective size Dge from combined lidar and radar measurements. In the algorithm, the lidar extinction ...
Evaluation of the Lidar–Radar Cloud Ice Water Content Retrievals Using Collocated in Situ Measurements
Publisher: American Meteorological Society
Abstract: emote sensing and in situ measurements made during the Colorado Airborne Multiphase Cloud Study, 2010?2011 (CAMPS) with instruments aboard the University of Wyoming King Air aircraft are used to evaluate lidar?radar-retrieved ...
Cloud Type and Macrophysical Property Retrieval Using Multiple Remote Sensors
Publisher: American Meteorological Society
Abstract: A cloud detection algorithm based on ground-based remote sensors has been developed that can differentiate among various atmospheric targets such as ice and water clouds, virga, precipitation, and aerosol layers. Standard ...
Cirrus Cloud Microphysical Property Retrieval Using Lidar and Radar Measurements. Part II: Midlatitude Cirrus Microphysical and Radiative Properties
Publisher: American Meteorological Society
Abstract: The lidar?radar algorithm described in Part I of this set of papers is applied to ?1000 h of Raman lidar and millimeter wave cloud radar (MMCR) data collected at the Atmospheric Radiation Measurement program Southern Great ...
Contrails of Small and Very Large Optical Depth
Publisher: American Meteorological Society
Abstract: This work deals with two kinds of contrails. The first comprises a large number of optically thin contrails near the tropopause. They are mapped geographically using a lidar to obtain their height and a camera to obtain ...
Contrails to Cirrus—Morphology, Microphysics, and Radiative Properties
Publisher: American Meteorological Society
Abstract: This work is two pronged, discussing 1) the morphology of contrails and their transition to cirrus uncinus, and 2) their microphysical and radiative properties. It is based upon the fortuitous occurrence of an unusual set ...
Anvil Productivities of Tropical Deep Convective Clusters and Their Regional Differences
Publisher: American Meteorological Society
Abstract: he anvil productivities of tropical deep convection are investigated and compared among eight climatological regions using 4 yr of collocated and combined CloudSat and CALIPSO data. For all regions, the convective clusters ...
Improved Radar Ice Water Content Retrieval Algorithms Using Coincident Microphysical and Radar Measurements
Publisher: American Meteorological Society
Abstract: Airborne radar reflectivity measurements at frequencies of 9.6 and 94 GHz, with collocated, in situ particle size distribution and ice water content measurements from the Cirrus Regional Study of Tropical Anvils and Cirrus ...
Droplet Concentration and Spectral Broadening in Southeast Pacific Stratocumulus Clouds
Publisher: American Meteorological Society
Abstract: everal airborne field experiments have been conducted to verify model descriptions of cloud droplet activation. Measurements of cloud condensation nuclei and updraft are inputs to a parcel model that predicts droplet ...
