Supervised vicarious calibration (SVC) of hyperspectral remote-sensing data

Remote Sensing of Environment, 2011
A full-chain process approach to extracting reflectance information from hyperspectral (HRS) data which is valid for all sensor qualities is proposed. This method is based on a mission-by-mission approach, followed by a unique vicarious calibration stage.

Vicarious Calibration of Global Precipitation Measurement Microwave Radiometers [PDF]

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
The vicarious cold calibration method of Ruf has been used to assess the calibration of the TMI, WindSat, SSM/I F13 and SSM/I F14 microwave radiometers using data from the GPM Inter-Calibration Working Group. Significant scan position dependent biases are seen for TMI (as large as 1 K) and for WindSat (as large as 5 K)-scan position dependent biases in

Vicarious Calibration of ASTER via the Reflectance-Based Approach

IEEE Transactions on Geoscience and Remote Sensing, 2008
The reflectance-based vicarious calibration approach has been applied to the Advanced spaceborne Thermal emission and reflection radiometer (ASTER) that is on the Terra platform. The results from three separate groups operating at the same sites at the same time are presented.

Spatio-Temporal Assessment of Tuz Gölü, Turkey as a Potential Radiometric Vicarious Calibration Site [PDF]

Remote Sensing, 2014
The paper provides an assessment of Tuz Gölü, a site in Turkey proposed for the radiometric vicarious calibration of satellite sensors, in terms of its spatial homogeneity as expressed in visible and near-infrared (VNIR) wavelengths over a 25-year period

Sources of uncertainty in vicarious calibration: understanding calibration target re .ectance [PDF]

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
A field experiment investigated the hypothesis that the nadir reflectance of calibration surface substrates (asphalt and concrete) remains stable over a range of time-scales. Measurable differences in spectral reflectance factors were found over periods as short as 30 minutes.

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.

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 ...

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.

Compositional characterisation of the pinnacles vicarious calibration site

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
Earth Observation (EO) satellite data are the single most important and richest source of environmental information for Australia. It is expected that future imaging spectroscopy satellites will be important for Australia for accessing critical information for managing natural and non-renewable resources, such as dry plant matter and mineralogy, which ...
