Calibration of SeaWiFS II Vicarious techniques

Applied Optics, 2001
We present an overview of the vicarious calibration of the Sea-Viewing Wide Field-of-view Sensor (SeaWiFS). This program has three components: the calibration of the near-infrared bands so that the atmospheric correction algorithm retrieves the optical properties of maritime aerosols in the open ocean; the calibration of the visible bands against in ...

Microwave radiometer inter-calibration using the vicarious calibration method

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
The vicarious cold and warm calibration methods of Ruf, and Brown and Ruf, have been used to assess the calibration of the WindSat radiometer as well as the biases of the TMI, SSM/I F13 and SSM/I F14 radiometers relative to WindSat. WindSat biases computed as a function of scan position are consistent with a roll offset of the instrument of ⋅2° and a ...

Vicarious calibration of KOMPSAT-3 AEISS

SPIE Proceedings, 2015
This paper presents a vicarious radiometric calibration of the Korea Multi-Purpose Satellite-3 (KOMPSAT-3) performed by the Korea Aerospace Research Institute (KARI) and the Pukyong National University Remote Sensing Group (PKNU RSG) in 2012 and 2014. Correlations between top-of-atmosphere (TOA) radiances and the spectral band responses of the KOMPSAT ...

Preflight and Vicarious Calibration of Artemis

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
Pre-flight and on-orbit calibration of the spectral imagery acquired with the Advanced Responsive Tactically Effective Military Imaging Spectrometer (ARTEMIS) will make use of solar radiation-based methods. Preflight spectral calibration relies on views of a specially-coated to provide a set of known absorption features.

Vicarious Radiometric Calibrations of EOS Sensors

Journal of Atmospheric and Oceanic Technology, 1996
Abstract Four methods for the in-flight radiometric calibration and cross calibration of multispectral imaging sensors are described. Three make use of ground-based reflectance, irradiance, and radiance measurements in conjunction with atmospheric measurements and one compares calibrations between sensors.

HISUI vicarious calibration and CAL/VAL activities

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
The Hyperspectral Imager Suite (HISUI) is the Japanese next-generation Earth observation project, and is being developed by Japanese Ministry of Economy, Trade, and Industry (METI). We conduct the vicarious calibration for HISUI instrument as the pre-launch activities in summer in the southern hemisphere.

EOS ASTER thermal infrared band vicarious calibration

SPIE Proceedings, 2001
Calibration of the five EOS ASTER instrument emission bands (90 m pixels at surface) is being checked during the operational life of the mission using field measurements simultaneous with the image acquisition. For water targets, radiometers, temperature measuring buoys and local radiosonde atmospheric profiles are used to determine the average water ...

Automated test-site radiometer for vicarious calibration

SPIE Proceedings, 2014
In order to realize unmanned vicarious calibration, Automated Test-site Radiometer (ATR) was developed for surface reflectance measurements. ATR samples the spectrum from 400nm-1600 nm with 8 interference filters coupled with silicon and InGaAs detectors. The field of view each channel is 10 ° with parallel optical axis.

Unmanned vicarious calibration for large-footprint sensors

SPIE Proceedings, 2005
The Remote Sensing Group (RSG) at the University of Arizona is currently developing inexpensive, unmanned radiometers based on light-emitting diodes (LEDs). This work describes these radiometers, which are now used as part of the extensive vicarious calibration research that has been conducted since the mid-1980s and presently includes such sensors as ...

Vicarious Calibration of Orbiting Carbon Observatory-2

IEEE Transactions on Geoscience and Remote Sensing, 2019
Vicarious calibration methods use well-characterized surface sites to complement other on-orbit radiometric calibration techniques. Since 2009, NASA’s Orbiting Carbon Observatory-2 (OCO-2) and Japan’s Greenhouse gasses Observing SATellite teams have conducted annual campaigns at Railroad Valley, NV, USA, for this purpose.
