Effects of Rain Gauge Temporal Resolution on the Specification of a Z–R Relationship
Journal of Atmospheric and Oceanic Technology - Tập 26 Số 7 - Trang 1302-1314 - 2009
Punpim Puttaraksa Mapiam, Nutchanart Sriwongsitanon, Siriluk Chumchean, Ashish Sharma
Abstract The weather radar is an efficient alternative for measuring spatially varying rainfall covering a large area at a high temporal resolution. This paper studies the impact of rainfall gauge temporal resolution on optimal relationships between radar reflectivity (Z) and rainfall rate (R). Four datasets of radar reflectivity and corresponding ra...... hiện toàn bộ
Removing Solar Radiative Effect from the VIIRS M12 Band at 3.7 μm for Daytime Sea Surface Temperature Retrievals
Journal of Atmospheric and Oceanic Technology - Tập 31 Số 11 - Trang 2522-2529 - 2014
Quanhua Liu, Alexander Ignatov, Fuzhong Weng, Xingming Liang
AbstractOperational sea surface temperature (SST) retrieval algorithms are stratified into nighttime and daytime. The nighttime algorithm uses two split-window Visible Infrared Imaging Radiometer Suite (VIIRS) bands—M15 and M16, centered at ~11 and ~12 m, respectively—and a shortwave infrared band—M12, centered at ~3.7 m. The M12 is most transparent and critical for accurate SST retrievals. However, it is not used during the daytime because of contamination by solar radiation, which is reflected by the ocean surface and scattered by atmospheric aerosols. As a result, daytime VIIRS SST and cloud mask products and applications are degraded and inconsistent with their nighttime counterparts. This study proposes a method to remove the solar contamination from the VIIRS M12 based on theoretical radiative transfer model analyses. The method uses either of the two VIIRS shortwave bands, centered at 1.6 hiện toàn bộ
Airborne and Ground-Based Measurements Using a High-Performance Raman Lidar
Journal of Atmospheric and Oceanic Technology - Tập 27 Số 11 - Trang 1781-1801 - 2010
David N. Whiteman, Kurt Rush, Scott D. Rabenhorst, Wayne Welch, Martin Cadirola, Gerry McIntire, Felicita Russo, Mariana Adam, D. D. Venable, R. Connell, Igor Veselovskii, Ricardo Forno, B. Mielke, Bernhard Stein, Thierry Leblanc, Stuart McDermid, Holger Vömel
Abstract A high-performance Raman lidar operating in the UV portion of the spectrum has been used to acquire, for the first time using a single lidar, simultaneous airborne profiles of the water vapor mixing ratio, aerosol backscatter, aerosol extinction, aerosol depolarization and research mode measurements of cloud liquid water, cloud droplet radiu...... hiện toàn bộ
Carbon Monoxide Urban Emission Monitoring: A Ground-Based FTIR Case Study

Turbulence Measurements from Five-Beam Acoustic Doppler Current Profilers
Journal of Atmospheric and Oceanic Technology - Tập 34 Số 6 - Trang 1267-1284 - 2017
Maricarmen Guerra, Jim Thomson
AbstractTwo new five-beam acoustic Doppler current profilers—the Nortek Signature1000 AD2CP and the Teledyne RDI Sentinel V50—are demonstrated to measure turbulence at two energetic tidal channels within Puget Sound, Washington. The quality of the raw data is tested by analyzing the turbulent kinetic energy frequency spectra, the turbulence spatial structure functi...... hiện toàn bộ
On the Transition from Profile Altimeter to Swath Altimeter for Observing Global Ocean Surface Topography
Journal of Atmospheric and Oceanic Technology - Tập 31 Số 2 - Trang 560-568 - 2014
Lee‐Lueng Fu, Clément Ubelmann
Abstract Conventional radar altimeter makes measurement of sea surface height (SSH) in one-dimensional profiles along the ground tracks of a satellite. Such profiles are combined via various mapping techniques to construct two-dimensional SSH maps, providing a valuable data record over the past two decades for studying the global ocean circulation an...... hiện toàn bộ
Geophysical Applications of Partial Wavelet Coherence and Multiple Wavelet Coherence
Journal of Atmospheric and Oceanic Technology - Tập 29 Số 12 - Trang 1845-1853 - 2012
Eric K. W. Ng, Johnny C. L. Chan
Abstract In this paper, the application of partial wavelet coherence (PWC) and multiple wavelet coherence (MWC) to geophysics is demonstrated. PWC is a technique similar to partial correlation that helps identify the resulting wavelet coherence (WTC) between two time series after eliminating the influence of their common dependence. MWC, akin to mult...... hiện toàn bộ
Development and Tests of a New Distributed-Memory MM5 Adjoint
Journal of Atmospheric and Oceanic Technology - Tập 23 Số 3 - Trang 424-436 - 2006
Frank H. Ruggiero, John Michalakes, Thomas Nehrkorn, George D. Modica, Xiaolei Zou
Abstract Updated versions of the Tangent Linear Model (TLM) and adjoint of the fifth-generation Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model (MM5) have been developed and are now available to the meteorological community. The previous version of the MM5 TLM and adjoint were designed for single-processor compu...... hiện toàn bộ
Vertical Air Motion from T-REX Radiosonde and Dropsonde Data
Journal of Atmospheric and Oceanic Technology - Tập 26 Số 5 - Trang 928-942 - 2009
Junhong Wang, Jianchun Bian, William O. Brown, Harold L. Cole, Vanda Grubı̆sı́c, Kathryn Young
AbstractThe primary goal of this study is to explore the potential for estimating the vertical velocity (VV) of air from the surface to the stratosphere, using widely available radiosonde and dropsonde data. The rise and fall rates of radiosondes and dropsondes, respectively, are a combination of the VV of the atmosphere and still-air rise–fall rates. The still-air...... hiện toàn bộ
Rainfall Estimation Accuracy of a Nationwide Instantaneously Sampling Commercial Microwave Link Network: Error Dependency on Known Characteristics
Journal of Atmospheric and Oceanic Technology - Tập 36 Số 7 - Trang 1267-1283 - 2019
Lotte de Vos, Aart Overeem, Hidde Leijnse, R. Uijlenhoet
AbstractCommercial microwave links are installed and maintained for the purpose of telecommunication. Hydrometeors between transmitting and receiving antennas cause the microwave signal to be attenuated. From signal attenuation, the path-averaged rainfall intensity can be calculated. A 7-month dataset of instantaneously logged signal powers from almost 2000 unique ...... hiện toàn bộ
