An increased frequency of extreme precipitation events has been observed over the last 100 years in the United States. Global climate models project that similar trends may continue and even strengthen over the coming decades, due to climate change.
NASA’s Jet Propulsion Laboratory, Pasadena, California, has completed the first comprehensive high-resolution topographic map of Central America, a region where persistent cloud cover had made high-quality satellite imagery difficult to obtain.
Researchers at NASA's Jet Propulsion Laboratory, Pasadena, California, have demonstrated a prototype device that automatically and continuously monitors the air for the presence of bacterial spores.
A solar-powered uninhabited aerial vehicle (UAV) successfully loitered more than four hours over Hawaii’s largest coffee plantation on the island of Kauai, taking digital images to make a “clear-sky” mosaic.
Recently, NASA has contributed weather and climate data to assist Pennsylvania state agencies in their response to the incidence of West Nile Virus throughout the Keystone state.
NASA researchers are conducting Earth Science research that may one day allow public health officials to better track and predict the spread of West Nile Virus. NASA’s goal is to provide people on the front lines of public health with innovative technologies, data and a unique vantage point from space through satellites, all tailored into useful tools and databases for streamlining efforts to combat the disease.
While many scientists and policy makers have focused only on how heat-trapping gases like carbon dioxide are altering our global climate, a new NASA-funded study points to the importance of also including human-caused land-use changes as a major factor contributing to climate change.
