4Geosynchronous Imaging FTS (GIFTS)
Combine Advanced Measurement Technologies On a
Geosynchronous Satellite to Obtain 4-D
Observations of the Atmosphere
- Horizontal Large detector arrays give near
instantaneous wide 2-D geographical coverage - Vertical Michelson interferometer (FTS) gives
high spectral resolution that yields high
vertical resolution - Temporal Geosynchronous orbit allows high time
resolution(i.e., motion observations)

12GIFTS and GOES-R Risk Reduction.
- What does NOAA GOES-RRR learn from
GIFTS?Thermal Vacuum Testing - Demonstrate optical design using high precision
internal calibration blackbodies for enhanced
accuracy from geo orbit. - Instrument Line Shape will be characterized for
an Imaging FTS. - Experience with FPA cross-talk, noise
correlation, linearity. - Experience gained in simulation of imaging GEO
sounder. - Development of metadata ontology for
hyperspectral observations. - Experience gained in the development and use of
high performance computing software as a
demonstration of future HES sounder ground data
processing (OSD).

IHOP 11 June 2002
Sense the low level moisture flux BEFORE the
convective clouds form!
19Previously our 4-km IHOP Simulation was of a
limited domain
MM5 Old Cluster
See Jason Otkin For details.
20WRF on SERENITY allows our 4 km domain to be
expanded
WRF SERENITY
See Jason Otkin For details.
21A FULL DISK run is possible at somewhat lower
spatial resolution.
