| Zusammenfassung |
| Advanced satellite sensors are tasked with improving global-scale
measurements of the Earth's atmosphere, clouds, and surface to enable
enhancements in weather prediction, climate monitoring, and environmental
change detection. Measurement system validation is crucial to achieving this
goal and maximizing research and operational utility of resultant data. Field
campaigns employing satellite under-flights with well-calibrated Fourier
Transform Spectrometer (FTS) sensors aboard high-altitude aircraft are an
essential part of this validation task. The National Polar-orbiting
Operational Environmental Satellite System (NPOESS) Airborne Sounder
Testbed-Interferometer (NAST-I) has been a fundamental contributor in this
area by providing coincident high spectral and spatial resolution
observations of infrared spectral radiances along with
independently-retrieved geophysical products for comparison with like
products from satellite sensors being validated. This manuscript focuses on
validating infrared spectral radiance from the Infrared Atmospheric Sounding
Interferometer (IASI) through a case study analysis using data obtained
during the recent Joint Airborne IASI Validation Experiment (JAIVEx) field
campaign. Emphasis is placed upon the benefits achievable from employing
airborne interferometers such as the NAST-I since, in addition to IASI
radiance calibration performance assessments, cross-validation with other
advanced sounders such as the AQUA Atmospheric InfraRed Sounder (AIRS) is
enabled. |
