August 27 — For 10 years, the DEVELOP program has pushed the envelope of the traditional summer internship, encouraging students into research projects with big implications for society. More
2007 Hurricane Forecasts Took Blow from Winds and Saharan Dry, Dusty Air
August 18 — A new analysis of environmental conditions over the Atlantic Ocean shows that hot, dry air associated with dust outbreaks from the Sahara desert was a likely contributor to the quieter-than-expected 2007 hurricane season. More
Project Anniversary Shows Value of Long-Term Investment in Climate Research
August 15 — The International Satellite Cloud Climatology Project (ISCCP) to study the role that clouds play in the climate celebrates its 25th anniversary this summer. More
NASA Study Lights Path to How Smoke Changes Cloud Cover, Climate
