Observing 3 (EO3) GIFTS-IOMI is a New Millennium Program's joint
mission with the US Navy's Office of Naval Research. GIFTS-IOMI
stands for Geosynchronous Imaging Fourier Transform Spectrometer
(GIFTS) Indian Ocean METOC Imager (IOMI). GIFTS is a highly
advanced instrument selected by NASA to perform as EO3's latest
weather observing instrument. Here are some interesting details
on the mission:
weather data from 35,405 kilometers (just over 22,000 miles) away in a geosynchronous orbit. This means it will remain in a fixed position relative to Earth, while flying in an equatorial orbit at the same speed and angle
as the Earths rotation. This allows the instrument to always
"stare" at us.
GIFTS instrument uses over 32,600 sensors to collect data, scanning
an area of 510 kilometers (just over 317 miles square) every ten seconds (data collected
that fast is called near-real-time).
will collect atmospheric data that helps scientists to analyze
temperature, wind patterns, cloud cover, water vapor, and pollutants
in our atmosphere.
will help improve the accuracy of weather forecasting for the
next decade by providing up-to-the-minute information, never before
available, on severe weather such as hurricanes and tornadoes.
collected during the mission will be available as part of the
GIFTS education and public outreach programs.
objective is to demonstrate and flight qualify advanced technologies
for application to future space missions and to provide better
meteorological and atmospheric chemistry data products (results).
