TOMS-EP

TOMS-EP [NASA]

TOMS-EP (Total Ozone Mapping Spectrometer - Earth Probe) is contributing to NASA's long-term daily monitoring of the global distribution of the Earth's ozone layer. The satellite was built by TRW for NASA's Goddard Space Flight Center (GSFC). Launch failures of the first two Pegasus-XL vehicles have caused a 2 year delay in the launch of TOMS-EP. These delays have caused the mission to be altered. TOMS-EP has been placed into a lower orbit than originall planned in a effort to achieve higher resolution measurements and to study UV-absorbing aerosols in the troposphere more thoroughly. The lower orbit will therefore complement measurements taken from ADEOS TOMS.
