Following an in-depth performance review by NASA and the French Centre National d'Etudes Spatiales, the Jason 1 oceanography satellite has been declared ready for operational service.
NASA's Global Change Master On-line Directory (GCMD) 2002 provides descriptions of Earth science data sets and services relevant to global change research. This directory will help students and scientists find a wealth of data from NASA's Earth science program and other organizations.
In a move to improve global weather forecasts and ultimately save lives and property, the United States and Europe have incorporated wind speed and direction data from NASA's Quick Scatterometer spacecraft -- also known as Quikscat -- into their operational global weather analysis and forecast systems.
A new image from the Multi-angle Imaging SpectroRadiometer instrument on NASA's Terra spacecraft shows the pattern of airborne dust stirred up by Santa Ana winds on February 9, 2002.
This month, dozens of scientists on the ground, in the air and using satellite observations will begin a multi-year experiment to study winter snow packs on the Colorado side of the Rocky Mountains. The purpose of this NASA-funded experiment is to improve the estimation of snow amount and forecasting of spring flooding due to snowmelt, and to study the role of cold lands within the Earth's climate.
NASA scientists and other researchers will present four symposiums this weekend concerning the latest advances in severe weather detection, the complex changes in global snow and ice, global environmental monitoring and the interactions of aerosols and climate.
A new sensor orbiting the Earth aboard NASAs Terra satellite is now collecting the most detailed measurements ever made of the seas surface temperature every day all over the globe. Like a sophisticated thermometer in space, the Moderate-resolution Imaging Spectroradiometer (MODIS) is helping Earth scientists advance studies of how our worlds oceans and atmosphere interact in ways that drive weather patterns and, over the long term, define our climate.
Newly released images and animation from a trio of NASA spacecraft instruments capture the varied desert-to-mountain landscape and colors of the Salt Lake City, Utah region, home to the 19th Winter Olympic Games, to be held February 8 - 24.
A new generation of thrusters has been used to precisely guide and point a satellite in space, paving the way for use of this technology on future spacecraft to save weight, fuel and cut power consumption.
By observing climate variability from space with satellites, scientists are working to determine where disease epidemics such as rift Valley Fever are likely to occur on Earth.
A NASA-funded study uses temperature and vegetation data from satellites to help track and predict where West Nile Virus is spreading in North America. Scientists and public health officials hope one day to use near real-time maps to focus resources and stave off the disease more efficiently.
