New AVHRR Reflectance Calibration Method
Demonstrated: Previous methods for the post launch
calibration of the Advanced Very High Resolution Radiometer (AVHRR)
reflectance channels involved calibrating each satellite
independently. As part of the AVHRR reprocessing initiative in
STAR, we are attempting to rederive post-launch calibrations that are
more accurate and but also provide consistent results for all AVHRRs.
This method uses the relative ratio of nadir observations coincident in
time and space from two AVHRRs and thereby forces the calibration of
one AVHRR to be dependent on those of the other AVHRRs. Shown
below are the results for the channel 2 calibration for
NOAA-11,-12,-14,-15,-16 and -17. The calibration slope data points are
derived from NASA's Moderate Resolution Imaging Spectroradiometer after
the year 2000 and the data points before 2000 are from aircraft or
other well validated sources. The important point is that the
derived (preliminary) calibration curves from this method match both
the observed calibration slopes and their intersatellite ratios. (A. Heidinger, E/RA2,

Abstract Submitted to EUMETSAT Conference: An abstract was submitted to the 2004 EUropean organization for the exploitation of METeorological SATellites (EUMETSAT) Meteorological Satellite Conference, to be held in Prague, Czech Republic, May 31 - June 4, 2004. The abstract is entitled "Comparing and contrasting the spectral bands of the Spinning Environmental Visible and InfraRed Instrument (SEVIRI) on Met-8 and the next generation Geostationary Operational Environmental Satellite (GOES) imagers". The authors are T. Schmit, M. Gunshor, W. P. Menzel and J. Gurka. (T. Schmit, E/RA2, 608-263-0291)
Extended Abstracts Submitted to AMS Sixth
Conference on Atmospheric Chemistry/Air Quality in Megacities:
Two extended abstracts were submitted to the Annual American
Meteorological Society (AMS) Sixth Conference on Atmospheric Chemistry:
Air Quality in Megacities to be held in Seattle in January 2004.
The titles are "Utilizing MODIS (MODerate-resolution Imaging
Spectroradiometer) Satellite Observations to Monitor and Analyze A Fine
Particulate Matter, PM2.5, Transport Event" and "Utilizing MODIS
Satellite Observations in Near-Real-Time to Improve AIRNow Next Day
Forecast of Fine Particulate Matter, PM2.5." Both papers include
applications of the Geostationary Operational Environmental Satellite
Wildfire Automated Biomass Burning Algorithm (WF_ABBA) fire products in
this air quality data fusion analysis and forecasting effort in the
United States. E. Prins serves as a co-author on these
papers. (E. Prins,

More Extended Abstracts for AMS Annual Meeting: An extended abstract entitled "A Study of Data and Products From the GOES-9 Imager and Sounder Over the Western Pacific Ocean", was prepared for the 20th International Conference on Interactive Information and Processing Systems (IIPS) for Meteorology, Oceanography, and Hydrology, to be held this January at the 84th Annual American Meteorological Society (AMS) Meeting in Seattle. The authors are J. P. Nelson III, G. S. Wade, A. J. Schreiner, T. J. Schmit, W. F. Feltz, and C. C Schmidt. (J. Nelson, CIMSS, 608-263-6013, G. S. Wade, E/RA2, 608-263-4743, T.
