New
AVHRR Reflectance Calibration Offers More Intersatellite Consistency:
Part of ORA's Advanced Very High Resolution Radiometer (AVHRR) Data
Stewardship effort involves improving the calibration of the
reflectance channels, which have no onboard calibration
source. One of the big challenges to using AVHRR
for climate studies is to develop a consistent radiometric record from
the various AVHRR instruments. We have developed new techniques to
calibrate the afternoon instruments and transfer the calibration from
the afternoon instruments to the morning
instruments. During periods when the afternoon
satellites are replaced (e.g., NOAA-11 to NOAA-14) and the morning
satellite is continuous (e.g., NOAA-12), the smoothness of the inferred
morning instrument reflectance calibration can be used to measure the
relative continuity of the reflectance calibration between the two
afternoon instruments. As the attached figure shows, the new
calibration derived from the AVHRR Pathfinder Atmosphere Extended
(PATMOS-x) project produces a NOAA-12 AVHRR channel 1 calibration curve
that is much more continuous over the NOAA-11 and NOAA-14 transition
(which occurred in 1994) than the published calibrations used in NASA
Land Pathfinder (labeled VS) and the previous AVHRR Pathfinder
Atmosphere (labeled RCS). This methodology can also play a
role in the verification of the radiometric continuity of AVHRR's
follow-on instrument, the Visible and Infrared Imaging Radiometer Suite
(VIIRS). (A. Heidinger, E/RA2, 608-263-6757)

FOR THE DIVISION CHIEF, ARAD
Abstract submitted to SPIE Annual Meeting:
An abstract entitled "Using ABI to help HES for cloud property and
atmospheric sounding retrieval" has been submitted to Weather and
Environmental Satellites II of the Society of Photo-Optical
Instrumentation Engineers (SPIE)'s annual meeting to be held in San
Diego, California from July 31 to August 4, 2005. Coauthors are
Jun Li, Chian-Yi Liu, Timothy J. Schmit, James J. Gurka and W. Paul
Menzel. (Jun Li, CIMSS, 608-262-3755)
Other Meetings and Telecons:
(None)
VISITORS:
NEXT WEEK:
T. Schmit will give an invited talk at
an Optical Society of America (OSA) conference in Alexandria,
VA on January 31, 2005. The meeting is "Hyperspectral Imaging and
Sounding of the Environment". The title of the presentation is
"Applications of the GOES-R HES (Hyperspectral Environmental Suite)
Infrared measurements". The co-authors are James Gurka, W. P. Menzel,
and Jun Li of the Cooperative Institute for Meteorological
Satellite Studies (CIMSS).
A. Heidinger will attend and chair the VIIRS Operational Algorithm Team
meeting in California.
J. Key will attend the NOAA Arctic Climate Science Priorities workshop
in Silver Spring, February 2-3. The goal of the meeting is to
develop a set of recommendations to guide NOAA priorities and plans for
the Arctic over the 2006-20012 timeframe, including near-term plans and
initial coordination with the International Polar Year (IPY).
