RISCloud Classification of AVHRR Imagery in Maritime Regions Using a Probabilistic Neural Network
Publisher: American Meteorological Society
Abstract: Using Advanced Very High Resolution Radiometer data, 16 pixel ? 16 pixel sample areas are classified into one of ten output classes using a probabilistic neural network (PNN). The ten classes are cirrus, cirrocumulus, ...
Data Mining Numerical Model Output for Single-Station Cloud-Ceiling Forecast Algorithms
Publisher: American Meteorological Society
Abstract: Accurate cloud-ceiling-height forecasts derived from numerical weather prediction (NWP) model data are useful for aviation and other interests where low cloud ceilings have an impact on operations. A demonstration of the ...
Optimization of an Instance-Based GOES Cloud Classification Algorithm
Publisher: American Meteorological Society
Abstract: An instance-based nearest-neighbor algorithm was developed for a Geostationary Operational Environmental Satellite (GOES) cloud classifier. Expert-labeled samples serve as the training sets for the various GOES image ...
Cluster Analysis of A-Train Data: Approximating the Vertical Cloud Structure of Oceanic Cloud Regimes
Publisher: American Meteorological Society
Abstract: oderate Resolution Imaging Spectroradiometer (MODIS) data continue to provide a wealth of two-dimensional, cloud-top information and derived environmental products. In addition, the A-Train constellation of satellites ...
Improvement to a Neural Network Cloud Classifier
Publisher: American Meteorological Society
Abstract: Examination of various feature selection algorithms has led to an improvement in the performance of a probabilistic neural network (PNN) cloud classifier. Thee algorithms reduce the number of network inputs by eliminating ...
An Automated Method to Estimate Tropical Cyclone Intensity Using SSM/I Imagery
Publisher: American Meteorological Society
Abstract: An automated method to estimate tropical cyclone intensity using Special Sensor Microwave Imager (SSM/I) data is developed and tested. SSM/I images (512 km ? 512 km) centered on a given tropical cyclone (TC), with a known ...
