Recent Advances in University of Wyoming King Air Observation Capabilities
February 17, 2017 11:15 am
ATS 101
Presented by: Zhien Wang
Hosted by: Sue Van Den Heever
University of Wyoming
University of Wyoming King Air (UWKA) is a part of NSF-supported Lower Atmosphere Observing Facilities (LAOF). Through multi-year development efforts, UWKA has equipped with integrated observation capabilities for cloud dynamics and microphysics, aerosols, and environment conditions through combining lidar, radar, radiometer and in situ measurements. Approaches were developed to retrieve droplet and ice concentrations in… Read more »
Deep Machine Learning for High-Impact Weather Forecasting
February 10, 2017 11:15 am
ATS 101
Presented by: David John Gagne
Hosted by: Greg Hermand & Russ Schumacher
NCAR
The weather forecasting process has grown more complex in recent years with the growing amount of observational data and model output available to weather forecasters and the trend toward providing more impact-based decision support services. In order to assist forecasters and end-users with the task of managing the firehose of data, I have developed and… Read more »
Seasonal Variability of Warm Boundary Layer Cloud and Precipitation Properties in the Southern Ocean as Diagnosed from A-Train and Ship-Based Remote Sensing Data
February 3, 2017 11:15 am
ATS 101
Presented by: Jay Mace
Hosted by: Paul DeMott
University of Utah
The extensive cloudiness and resulting high albedo of the Southern Oceans (SO) are predominantly due to the occurrence of widespread marine boundary layer (MBL) clouds. Recent work finds correlations between biogenically enhanced cloud condensation nuclei concentrations and cloud droplet number concentrations derived from passive satellite data. The active remote sensors in the A-Train have created… Read more »
Sensing Hazards with Operational Unmanned Technology
February 3, 2017 10:00 am
CIRA Directors Conference Room
Presented by: Andrew Kren
Hosted by:
NOAA ESRL
A key project within the National Oceanic and Atmospheric Administration (NOAA) Global Observing Systems Analysis (GOSA) group is the Sensing Hazards with Operational Unmanned Technology (SHOUT) project. One of the main objectives of SHOUT is to conduct both Observing System Experiments (OSEs) and Observing System Simulation Experiments (OSSEs) to evaluate the impact of real and… Read more »
Pressure Perturbations in Cumulus Convection
January 20, 2017 11:15 am
ATS 101
Presented by: John Peters
Hosted by: Russ Schumacher
CSU Postdoctoral Fellow
Pressure perturbations are regions of anomalously low or high pressure in deep convection and play key roles in modulating the magnitude and distribution of vertical velocities within cumulus clouds. A cloud’s vertical momentum budget is primarily regulated by two pressure forces: Effective buoyancy pressure acceleration (EBPA), and dynamic pressure acceleration (DPA). I will first… Read more »
