*Dissertation Title: "Statistical models for quantifying the spatial distribution of seasonally derived ozone standards." (The data are a subset of the data found here, but note that the location is subject to change without my knowing it).
While working on the Ph.D. degree, I was a Research Assistant with NCAR's Geophysical Statistics Project (GSP). GSP is now part of the Institute for Mathematics Applied to Geosciences (IMAGe -- French pronunciation).

Information page on Software for Extreme Value Theory originally created by Alec Stephenson and currently maintained by me.
Software I either authored, co-authored, currently maintain, or have some other sort of association with.
distillery: This is a very simple package with some useful method functions used by extRemes (>= 2.0) and SpatialVx (>=0.1-6).
extRemes (Version >= 2.0) is command-line code extreme value analysis.
in2extRemes: point-and-click software operating some of the functionality included in extRemes.
RadioSonde: software for creating skew-T diagrams and plots with wind barbs.
SpatialVx: software for doing spatial weather forecast verification.
verification: routines predominantly written by Matt Pocernich for performing weather forecast verification.
MET: software package (based on C++) for forecast verification.

History of the English Language Presentations
Presentation on Frisian (and its connection to English) for IBM's 2009 Take Our Children to Work Day (pdf).
A blog about the British TV show, Doc Martin by Karen Gilleland
Piter Wilkens is one of the few singer/songwriter's to sing almost exclusively in the West Frisian language, Frisian (he has at least one song in Leeuwardish; a town Frisian dialect). The language was considered the closest living language to English until it was decided that Scots should be considered a separate language (rather than dialect).
