February 25 — 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. More

NASA's Quikscat Spacecraft Turns Operational
February 22 — 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. More

Santa Ana Winds Swirl Through the Southland
February 22 — 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. More

Snow Science, Not Sport, in the Rockies
February 15 — 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.

Highlights From NASA Presentations at AAAS Symposium
February 14 — 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. More

Terra Measures Sea Surface Temperature with Unprecedented Detail
February 14 — A new sensor orbiting the Earth aboard NASA’s Terra satellite is now collecting the most detailed measurements ever made of the sea’s 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 world’s oceans and atmosphere interact in ways that drive weather patterns and, over the long term, define our climate.

NASA Images Capture Golds, Silvers and Bronzes of Utah Olympic Site
February 7 — 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. More

Thrusters Precisely Guide EO-1 Satellite In Space First
February 7 — 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. More

Satellites Tracking Climate Changes and Links to Disease Outbreaks in Africa
February 5 — 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. More

Satellites vs. Mosquitoes: Tracking West Nile Virus in the U.S
February 5 — 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. More
