Abstract
Assembling a multi-sensor set of data for, say, a volcanic eruption means days of wandering cyberspace to find data and pry it loose from the custom search interfaces that jealously guard it. Following the Search is a slog of weeks reading format and QA documents, then cobbling together code to beat the data into a form that can be used safely in analysis tools. Why so difficult?$%#@^%!???

Further Exploration
Interested in learning more about the technologies mentioned in this presentation? Here are some places to go and things to do:
Check out the ESIP Federated Search cluster for distributed search on a shoestring
Explore the wonders of OPeNDAP
- Get ASCII subsets of the data! Go to http://acdisc.sci.gsfc.nasa.gov/opendap/HDF-EOS5/Aura_OMI_Level3/OMAERUVd.003//2010/OMI-Aura_L3-OMAERUVd_2010m0131_v003-2010m0202t014811.he5.html, select the variables of interest and click ascii.
- View Level 3 gridded data in Panoply!
- First, download Panoply, an easy to use Java-based viewer for netCDF, HDF and GRIB data
- Open up Panoply, go to File-> Open Remote File, and paste in the following URL (N.B.: without .html extension): http://acdisc.sci.gsfc.nasa.gov/opendap/HDF-EOS5/Aura_OMI_Level3/OMAERUVd.003//2010/OMI-Aura_L3-OMAERUVd_2010m0131_v003-2010m0202t014811.he5
