Aerosols from Nimbus 7 TOMS: Transatlantic Dust Event in 1983
Saharan dust storms raise dust that is carried in the upper atmosphere across the Atlantic Ocean. That dust can land as far west as the Caribbean and the Americas. This dust can carry potentially hazardous bacteria and fungi.
Transatlantic Dust from North Africa (WMS)
Desert storms in northern Africa raise dust that is carried in the upper atmosphere across the Atlantic Ocean. The dust, which may carry potentially hazardous bacteria and fungi, can land as far west as the Caribbean and the Americas.
Continental Effects of 2004 Alaskan Fires (WMS)
Wildfires started by lightning burned more than 80,000 acres in Alaska in June 2004. The effects of these fires can be seen across North America with the Total Ozone Mapping Spectrometer (TOMS) instrument on the Earth Probe spacecraft. TOMS detects the presence of UV-absorbing tropospheric aerosols across the globe.
Aerosol Index over the Atlantic Ocean: July 1, 1988 to September 29, 1988
Aerosol index measurements indicating dust blowing westwards from Africa across the Atlantic Ocean during the period July 1, 1988 to September 29, 1988. as measured by Earth Probe TOMS
Sea Surface Temperature Anomalies during El Nino-La Nina Event of 1997-1998 (WMS)
The El Nino-La Nina event in 1997-1999 was particularly intense, but was also very well observed by satellites and buoys. A strong upwelling of unusually warm water was observed in the Pacific Ocean during the El Nino phase, followed by unusually cold water in the La Nina phase. The Advanced Very High Resolution Radiometer (AVHRR) instrument on the US National Oceanic and Atmospheric Administrations NOAA-14 spacecraft observed the changes in sea surface temperature shown here.
Infrared Astronomy: More Than Your Eyes Can See
This lithograph uses images of the well-known constellation of Orion to illustrate how a common astronomical object appears in both visible light and in the infrared. The back of the lithograph tells the history of infrared light and explains the benefits of infrared astronomy.
Intro to Information Privacy, Spring 2009
With the explosion of information technology, almost everyone has multiple computer and mobile devices that interact on the Internet. In addition, on-line social networking and sharing has become common place; for instance, Facebook, MySpace, and others. Personal information flows freely among us, even when taking a coffee break on a wireless network. Understanding how to protect your privacy is everyone’s business. This course gives an introduction to computer and network security from the pe
Yet Another Calculus Text
I intend this book to be, firstly, a introduction to calculus based on the hyperreal number system. In other words, I will use infinitesimal and infinite numbers freely. Just as most beginning calculus books provide no logical justification for the real number system, I will provide none for the hyperreals. The reader interested in questions of foundations should consult books such as Abraham Robinson's Non-standard Analysis or Robert Goldblatt's Lectures on the Hyperreals. Secondly, I have aime
Risk Management for Enterprises and Individuals
This book is intended for the Risk Management and Insurance course where Risk Management is emphasized. When we think of large risks, we often think in terms of natural hazards such as hurricanes, earthquakes or tornadoes Perhaps man-made disasters come to mind such as the terrorist attacks in the U.S. on September 11, 2001. Typically we have overlooked financial crises, such as the credit crisis of 2008. However, these types of man-made disasters have the potential to devastate the global mark

An Introduction to the Patent System
This 17-minute video is designed to be shown to jurors in patent jury trials. It contains important background information intended to help jurors understand what patents are, why they are needed, how inventors get them, the role of the Patent and Trademark Office, and why disputes over patents arise. An Introduction to the Patent System was developed with the assistance of an advisory committee of district judges and patent attorneys. Special care was taken to ensure that it provides an imparti
The goal of the Genetic Origins Program is to allow students to use their own DNA variations (polymorphisms) as a means to explore our shared genetic heritage and its implications for human health and society. Genetic Origins focuses on two types of DNA variations: an Alu insertion polymorphism on chromosome 16 (PV92) and single nucleotide polymorphisms (SNPs) in the control region of the mitochondrial (mt) chromosome. With two alleles and three genotypes, PV92 is a simple genetic system that il
"Ain't I a Woman?" Motherhood and Status Deprivation
The proposed exercises are to be used in my Sociology of Family and my Society and Power courses. The exercise would seem to work best with readings or discussions of gender, family structure, social stratification and life chances. The activity begins with a modified version of an SSDAN exercise created created by Elizabeth Jordan, "The Explosion of Teenage Motherhood: Myth or Reality?" The concluding activity, exercise 2, is designed to give students an introduction to generating and testing a
