Evaluation of Surface Temperature and Emissivity Derived from ASTER Data: A Case Study Using Ground-Based Measurements at a Volcanic Site
(American Meteorological Society, 2010)The land surface temperature (LST) and emissivity (LSE) derived from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data were evaluated in a low spectral contrast volcanic site at an altitude of ... -
AirCore: An Innovative Atmospheric Sampling System
(American Meteorological Society, 2010)This work describes the AirCore, a simple and innovative atmospheric sampling system. The AirCore used in this study is a 150-m-long stainless steel tube, open at one end and closed at the other, that relies on positive ... -
CloudSat as a Global Radar Calibrator
(American Meteorological Society, 2010)The calibration of the CloudSat spaceborne cloud radar has been thoroughly assessed using very accurate internal link budgets before launch, comparisons with predicted ocean surface backscatter at 94 GHz, direct comparisons ... -
Can CO2 Turbulent Flux Be Measured by Lidar? A Preliminary Study
(American Meteorological Society, 2010)The vertical profiling of CO2 turbulent fluxes in the atmospheric boundary layer (ABL) is investigated using a coherent differential absorption lidar (CDIAL) operated nearby a tall tower in Wisconsin during June 2007. A ... -
Real-Time Implementation of a Network-Based Attenuation Correction in the CASA IP1 Testbed
(American Meteorological Society, 2010)Monitoring of precipitation using higher-frequency radar systems such as X band is becoming popular. At X-band frequency, weather radar signals are attenuated along their paths due to precipitation. A network-based ... -
A VAD-Based Dealiasing Method for Radar Velocity Data Quality Control
(American Meteorological Society, 2010)This paper describes a new velocity?azimuth display (VAD)-based dealiasing method developed for automated radar radial velocity data quality control to satisfy the high-quality standard and efficiency required by operational ... -
Quality Assurance Procedures for Mesoscale Meteorological Data
(American Meteorological Society, 2010)Mesoscale meteorological data present their own challenges and advantages during the quality assurance (QA) process because of their variability in both space and time. To ensure data quality, it is important to perform ... -
A Balloon Sounding Technique for Measuring SO2 Plumes
(American Meteorological Society, 2010)This paper reports on the development of a new technique for inexpensive measurements of SO2 profiles using a modified dual-ozonesonde instrument payload. The presence of SO2 interferes with the standard electrochemical ... -
Automatic Detection of Wind Turbine Clutter for Weather Radars
(American Meteorological Society, 2010)Wind turbines cause contamination of weather radar signals that is often detrimental and difficult to distinguish from cloud returns. Because the turbines are always at the same location, it would seem simple to identify ... -
Viewing Geometry Dependencies in MODIS Cloud Products
(American Meteorological Society, 2010)Characterizing the earth?s global cloud field is important for the proper assessment of the global radiation budget and hydrologic cycle. This characterization can only be achieved with satellite measurements. For complete ... -
Automatic Minimum and Maximum Alarm Thresholds for Quality Control
(American Meteorological Society, 2010)Automated quality control is a necessity for meteorological measurement networks because of an ever-increasing number of measurements. One of the basic quality control tests is to check that the observations fall into a ... -
Deployment of a Tethered-Balloon System for Microphysics and Radiative Measurements in Mixed-Phase Clouds at Ny-Ålesund and South Pole
(American Meteorological Society, 2011)tethered-balloon system capable of making microphysical and radiative measurements in clouds is described and examples of measurements in boundary layer stratus clouds in the Arctic and at the South Pole are presented. A ... -
A Mixed Exponential Distribution Model for Retrieving Ground Flash Fraction from Satellite Lightning Imager Data
(American Meteorological Society, 2011)Bayesian inversion method is introduced for retrieving the fraction of ground flashes in a set of flashes observed from a (low earth orbiting or geostationary) satellite lightning imager. The method employs a constrained ... -
Empirical Correction of Stray Light within the MERIS Oxygen A-Band Channel
(American Meteorological Society, 2010)Spaceborne spectrometers like the Medium Resolution Imaging Spectrometer (MERIS) on board the Environmental Satellite (Envisat) are widely used for the remote sensing of atmospheric and oceanic properties and make an ... -
Effect of TRMM Orbit Boost on Radar Reflectivity Distributions
