distributed vertically from the upper troposphere to the stratosphere.
These observations should prove useful to understand chemical process, the
dynamics of the atmosphere, and the interaction between these processes and
atmospheric trace gas species to study the ozone depletion or the global
warming mechanism. This proposal was accepted in March 1997 and
SMILES is under phase A study, with a view towards a launch in 2002.

MISSIONS UNDER CONCEPTUAL STUDY
8.1
ADEOS-III
ADEOS-III is the ADEOS-II follow-on mission. Since 1997, a user
requirements definition study has been conducted within the science
community, the ADEOS-III Science Team of the Earth Science and
Technology Forum. Proposed sensors include AMSR-2, GLI-2, ODUS,
ILAS-3, SeaWinds-2, IMG-2, TERSE and GPSR. Feasibility studies are
planned for some of these sensors in 1997. Phase A is expected in FY 1998
while launch is scheduled in 2004.
8.2
ATMOS-A, B, C
ATMOS stands for Atmosphere Observing Satellite and the mission
concept is categorized into three types, which are A: Precipitation Mission,
B: Cloud Radiation Mission, C: Atmospheric (Chemistry, Wind) Missions.
ATMOS-A is a TRMM follow-on precipitation mission. The technical
feasibility study for 2.5t class mission had been done by NASDA and the
first iteration for the mission definition had been completed in April 1997. In
this study, a dual frequency precipitation radar PR-2, TMI and VIRS-2 are
considered as the core sensors. At present, a mission definition study is
being carried out in collaboration with NASA/GSFC.
ATMOS-B is a cloud/radiation mission. A feasibility study is planned in
the latter half of JFY 1997, and some of the results of ATMOS-A F/S are
applicable to ATMOS-B F/S. There are possible collaborative missions with
JPL’s CloudSat, if a joint proposal to NASDA’s MDS selected and possible
collaborative mission with ESA’s Earth Radiation Earth Explorer mission.
For these collaborations, joint/collaborative phase A is planned in 1998.
ATMOS-C is an atmospheric chemistry mission. The user requirements
definition study by ATMOS-C Science Team is on-going.
