APPROVED MISSIONS
6.1
TRMM
Tropical Rainfall Measuring Mission (TRMM) is a US-Japan joint
project to measure tropical rainfall and its variations, scheduled to be
launched on 1 November 1997. TRMM will carry five sensors: a
Precipitation Radar (PR) of 13.8 GHz, the five-frequency radiometer TRMM
Microwave Imager (TMI), the Visible Infrared Scanner similar to AVHRR
(VIRS), the Clouds and Earth’s Radiant Energy System (CERES) and the
Lightning Imaging Sensor (LIS).
The microwave radiometer TMI has a wide swath width (as much as 700
km) and can make quantitative rain measurement over oceans, PR can
measure the rain both over land and ocean and can provide vertical rainfall
profile, although its swath width is about 220 km and is thus narrower than
TMI.
The expected result from TRMM is to provide the three dimensional rain
rate distribution, the detailed vertical structure of rainfall, the vertically
integrated rain rate and the cloud height/properties in wide swath, and finally
the time/space averaged rainfall and the storm structure to users.
6.2
ADEOS-II
The mission objectives of ADEOS-II, as the successor of ADEOS, is to
acquire data contributing to the international global change research
program, as well as useful for applications such as meteorology and fishery.
Among various research areas, ADEOS-II is particularly dedicated to the
water, energy and carbon cycling. The data from ADEOS-II are expected to
be used by international research programs such as the Global Energy and
Water Cycling Research Experiment (GEWEX), the Climate Variability
Research (CLIVAR) Program and the International Geosphere and
Biosphere Research Program (IGBP).
SeaWinds, POLDER and ILAS-II data will be provided to both
international and domestic partners in addition to data from the Advanced
Microwave Scanning Radiometer (AMSR) and the Global Imager (GLI).
ADEOS-II satellite and related ground segments are under development,
with launch currently planned in 2001.
