Map of UV Exposure in the United States

NASA Earth Observatory:

The NASA Applied Sciences Program has partnered with the Centers for Disease Control and Prevention (CDC) to create the first publicly available map of ultraviolet (UV) radiation for all counties in the contiguous United States. The dataset, which spans 2005-2015, is available on the CDC’s National Environmental Public Health Tracking network, which delivers information and data about health issues related to environmental factors. Public health officials, city planners, or individuals concerned about Sun exposure can learn how much ultraviolet radiation is falling over each county each month, which is an important step in helping reduce skin cancer risks.

The animated map above shows the monthly average UV dose in 2015.

The CDC, Cholera Maps and the 2011 Haiti Epidemic

A map on a display at the CDC’s in-house museum hides in plain sight what U.S. government authorities are reluctant to admit: the origin of the 2011 cholera epidemic in Haiti (a U.N. peacekeeping base housing a batallion from Nepal). All the more amazing by its juxtaposition with John Snow’s famous 1854 cholera map of London. It’s as if they wanted us to tell us something while being prevented from doing so.
