TIMED: ThermosphereIonosphereMesophere Energetics & Dynamics
SABER:Sounding of the Atmosphere UsingBroadband Emission Radiometry
* There are fewer molecules in the MLTI, affecting how the atmosphere radiates & absorbs heat. This includes fewer aerosols.
TIMED is the satellite which will study the variability of the Mesosphere & Lower Thermosphere/Ionosphere region (MLTI).
SABER is one of the four instruments on board the TIMED spacecraft.
Types of Measurements:
When sunlight comes into contact with chemically active molecules, the atmosphere emits energy through photochemical processes known as airglow. Red = high airglow emission / Blue = low airglow emission. (http://oea.larc.nasa.gov/PAIS.SABER.html)

SABER will make the first-ever measurements of the global distribution of carbon dioxide concentrations in the MLTI region.
SABER will also provide the first measurements of ozone during the day & at night in the MLTI region.

TIMEDTeacher’s Lesson Plan
Middle School Activity distribution of carbon dioxide concentrations in the MLTI region.- 'How SABER 'Sees' the Earth' (developed at W.E. Waters Middle School, Portsmouth, VA)See how a hula-hoop can simulate TIMED's sun-synchronous orbit as it revolves around the Earth as Earth orbits around the sun. At the same time, learn how the instrument looks NOT at the Earth itself, but through the atmospheric limb, & how this provides several unique, first-time measurements.Classroom Activities
High School Activity - 'Exothermic & Endothermic Chemical Reactions of Hot & Cold Materials (developed at Perquimans’ County High School, Hertford, NC) Are you looking for a new way to teach your students about remote sensing? Our website will show you how to use a cola can to build a remote sensing tool that demonstrates the science behind the SABER instrument riding on the TIMED satellite.
