Tropopause-Penetrating Convection from Three-Dimensional Gridded NEXRAD Data

Anewmethod that combines radar reflectivities from individualNextGenerationWeatherRadars (NEXRAD) into a three-dimensional composite with high horizontal and vertical resolution is used to estimate storm-top altitudes for the continental United States east of the RockyMountains. Echo-top altitudes are compared with the altitude of the lapse-rate tropopause calculated from the ERA-Interim reanal...

CUDA-Accelerated HD-ODETLAP: Lossy High Dimensional Gridded Data Compression

We present High-dimensional Overdetermined Laplacian Partial Differential Equations (HD-ODETLAP), a high dimensional lossy compression algorithm and CUDA implementation that exploits data correlations across multiple dimensions of gridded GIS data. Exploiting the GPU gives a considerable speedup. In addition, HD-ODETLAP compresses much better than JPEG2000 and 3D-SPIHT, when fixing either the a...

Online Inertia Constant and Thévenin Equivalent Estimation Using PMU Data

In this paper a new algorithm based on phasor measurements for estimating the Thévenin Equivalent (TE) and system inertia constant is proposed. The method estimates the network TE seen from a generator terminal and equivalent system inertia constant by means of phasor data that is available at Phasor Data Concentrator (PDC) center. It is shown that the parameters of the TE could be estimated at...

Objective Identification of Trough Lines Using Gridded Wind Field Data

An objective method was developed to analyze longwave and shortwave trough lines in wind field data using different methods, given that these trough lines were researched in different ways. Longwave trough lines were analyzed by locating the cyclonic center and filtering candidate trough points simultaneously; the candidate longwave trough points were then traced based on distance and angle con...

Visualizing Multi-Dimensional Data

High dimensional data visualization is very important in data analysts since it gives a direct and natural view of data. In this paper, we propose a method to visualize large amount of high dimensional data in a 3-D space. In our method, we divide the high dimension data into several groups of lower dimensional data first. Then, we use different icons to represent different groups. Initial expe...
