  10. Data Mining / Earth Science Collaboration: Tropical Cyclone Detection Advanced Microwave Sounding Unit (AMSU-A) Data • Mining Plan: • Water cover mask to eliminate land • Laplacian filter to compute temperature gradients • Science Algorithm to estimate wind speed • Contiguous regions with wind speeds above a desired threshold identified • Additional test to eliminate false positives • Maximum wind speed and location produced Further Analysis Calibration/ Limb Correction/ Converted to Tb Knowledge Base Data Archive Hurricane Floyd Mining Environment Result Results are placed on the web, made available to National Hurricane Center & Joint Typhoon Warning Center, and stored for further analysis

  11. Data Mining / Earth Science Collaboration: Classification Based on Texture Features Cumulus cloud fields have a very characteristic texture signature in the GOES visible imagery • Science Rationale: Man-made changes to land use cause changes in weather patterns, especially cumulus clouds • Comparison based on • Accuracy of detection • Amount of time required to classify

  12. Parallel Version of Cloud Extraction • GOES images can be used to recognize cumulus cloud fields • Cumulus clouds are small and do not show up well in 4km resolution IR channels • Detection of cumulus cloud fields in GOES can be accomplished by using texture features or edge detectors Master Slave 1 Slave 2 Slave 3 GOES Image Laplacian Filter Sobel Horizontal Filter Sobel Vertical Filter Energy Computation Energy Computation Energy Computation Energy Computation Classifier Cloud Image GOES Image Cumulus Cloud Mask • Three edge detection filters are used together to detect cumulus clouds which lends itself to implementation on a parallel cluster

  13. Data Mining / Earth Science Collaboration: Detecting Signatures • Detecting mesocyclone signatures from Radar data • Science Rationale: Mesocyclone is an indicator of Tornadic activity • Developing an algorithm based on wind velocity shear signatures • Improve accuracy and reduce false alarm rates

  14. Data Mining / Space Science Collaboration:Boundary Detection and Quantification • Analysis of polar cap auroras in large volumes of spacecraft UV images • Scientific Rationale: • Indicators to predict geomagnetic storm • Damage satellites • Disrupt radio connection • Developing different mining algorithms to detect and quantify polar cap boundary Polar Cap Boundary

  16. Sensor Data Characteristics • Many different formats, types and structures • Different states of processing ( raw, calibrated, derived, modeled or interpreted ) • Enormous volumes • Heterogeneity leads to data usability problems

  17. Interchange Technologies: Accessing Heterogeneous Data The Problem DATA FORMAT 3 DATA FORMAT 1 DATA FORMAT 2 • Earth science data comes in: • Different formats, types and structures • Different states of processing (raw, calibrated, derived, modeled or interpreted) • Enormous volumes • Heterogeneity leads to data usability problems • One approach: Standard data formats • Difficult to implement and enforce • Can’t anticipate all needs • Some data can’t be modeled or is lost in translation • The cost of converting legacy data • A better approach: Interchange Technologies • Earth Science Markup Language FORMAT CONVERTER READER 1 READER 2 APPLICATION The Solution DATA FORMAT 1 DATA FORMAT 2 DATA FORMAT 3 ESML FILE ESML FILE ESML FILE ESML LIBRARY APPLICATION

  18. What is ESML? • It is a specialized markup language for Earth Science metadata based on XML - NOT another data format. • It is a machine-readable and -interpretable representation of the structure, semantics and content of any data file, regardless of data format • ESML description files contain external metadata that can be generated by either data producer or data consumer (at collection, data set, and/or granule level) • ESML provides the benefits of a standard, self-describing data format (like HDF, HDF-EOS, netCDF, geoTIFF, …) without the cost of data conversion • ESML is the basis for core Interchange Technology that allows data/application interoperability • ESML complements and extends data catalogs such as FGDC and GCMD by providing the use/access information those directories lack.
