L3Harris Selected to Lead
Advanced International Weather Satellite Study
April 07, 2022
L3Harris Technologies has been
awarded a contract by the Japan Meteorological Agency
(JMA) for an advanced study which will significantly
improve the accuracy and timing of Japan’s weather
forecasting.
L3Harris will lead the
geostationary hyperspectral infrared (IR) sounder study
for the JMA’s future enterprise. The six-month design
study began last month and allows L3Harris to evaluate
geostationary sounder instrument concepts. Sounders are
advanced spectrometers that produce high-resolution,
three-dimensional temperature and moisture profiles from
space. The study also will analyze performance, mature
the design, and develop ground processing algorithms for
prompt use of IR sounder data after launch.
"The data provided by L3Harris’
sounders and imagers improves both the accuracy of
weather forecasting days in advance and real-time severe
weather monitoring, which saves lives and property,
especially for extreme weather which impacts Japan, such
as typhoons, tsunamis, tornadoes, thunderstorms and
micrometeorological events,” said Rob Mitrevski, Vice
President and General Manager, Spectral Solutions, Space
and Airborne Systems, L3Harris. “Our technology
continues to play a critical role in improving severe
storm tracking and warnings. The more levels of data,
the better the forecast and monitoring.”
L3Harris’ most advanced
hyperspectral sounder, the Cross-track Infrared Sounder
(CrIS), is currently flying on the National Oceanic and
Atmospheric Administration’s (NOAA) Joint Polar
Satellite System (JPSS). The second JPSS satellite is
scheduled to launch this fall. Japan’s Himawari-8 and -9
satellites include L3Harris’ Advanced Himawari Imager
(AHI) onboard. AHI is similar to the Advanced Baseline
Imager on NOAA’s GOES-R series of satellites – GOES-T
launched in February. Last year, L3Harris was selected
by NASA to lead a similar Formulation Phase study for
NOAA’s Geostationary Extended Observations (GeoXO)
satellite sounder.
