The missiles have been test fired in endo- atmospheric region
( below the altitude of 40 km) on seven occasions and three in exo- atmosphere ( above an altitude of 80 km) region.
The Small North , a misty, atmospheric region
, provides a lush environment in which fresh grapes and tangy Pica Lemon s flourish.
TIMED is focusing on a portion of this atmospheric region
located approximately 40-100 miles (60-180 kilometers) above the surface.
Solar convection is the process that drives the rising and falling of gases in the lowest atmospheric region
, the photosphere.
TIMED will study how energy is transferred into and out of this atmospheric region
, as well as its basic structure.
