May marks the 20th anniversary of the launch of JPL’s Atmospheric Infrared Sounder (AIRS) aboard NASA’s Aqua satellite, on May 4, 2002. A selection of features, videos and animations highlight what AIRS has observed over the 20 years and the impact it has had.

Feature story: AIRS at 20 Years: A Bounty of Data

JPL Historian Erik Conway asks researchers what AIRS has revealed over 20 years in space and how its data are helping predict the weather, monitor trace gases, drought and volcanic plumes, and even forecast flu outbreaks.

Feature story: 20 Years of AIRS: A Story in Visualizations

The visualizations and images presented here show several quantities AIRS has observed over its 20 year lifetime. Most of these quantities have a common trait: the effects over the past two decades of human activities are easily seen in the AIRS observations. Some of these changes are more significant than was anticipated in the early 2000s.

NASA Facebook: Recording of Live Event with Dr. Joao Teixeira

For the last 20 years, AIRS (Atmospheric Infrared Sounder) data have been used to improve weather forecasts, climate models, and in applications from detecting volcanic plumes to forecasting drought. Lead scientist, Dr. Joao Teixeira, tells us more about the mission’s two-decade data record that supports climate research.


JPL and the Space Age: Sky High

Documentary: JPL and the Space Age: Sky High

NASA has been studying and monitoring the health of our home planet for decades, using balloons, aircraft, satellites, and even the International Space Station in the effort. “Sky High,” the 16th documentary in the series “JPL and the Space Age,” traces the efforts of NASA’s Jet Propulsion Laboratory to measure greenhouse gases, from the pathfinding science instrument AIRS, through to today’s Orbiting Carbon Observatory 3 aboard the space station.
