C-Band Satellite Scatterometer Intercalibration

IEEE Transactions on Geoscience and Remote Sensing, 2013
A methodology of intercalibration of C-band spaceborne scatterometers is developed and applied to European Remote Sensing satellite-1 (ERS-1), European Remote Sensing satellite-2 (ERS-2), and Meteorological Operational satellite (METOP) scatterometer data.

An intercalibration for trace metals in seawater

Marine Chemistry, 1981
Abstract This paper describes the results of a recent international intercalibration experiment for trace metals in seawater. The results show that considerable improvements in analytical ability have been made for several metals at concentrations close to those found in offshore marine waters.

Intercomparisons and Intercalibrations

2005
The institution of large-scale international cooperative research programs in the study of ocean systems has made more rigorous quality control over analytical procedures necessary. A series of intercalibration and intercomparison exercises have shown that increased care is needed in running even those determinations which have been run for years, and ...

Intercalibration of Low light level sources

Physics and Chemistry of the Earth, Part B: Hydrology, Oceans and Atmosphere, 2000
Abstract During the 26th Annual Meeting on Atmospheric Studies by Optical Methods an intercalibration of low level light sources was performed. The purpose of this calibration is to provide a comparable scale of intensities of auroral or airglow emissions.

A comparison of NDVI intercalibration methods

International Journal of Remote Sensing, 2017
ABSTRACTSensor differences pose a challenge when using normalized difference vegetation index (NDVI) data calculated from different sensors. Determining an optimal intercalibration strategy is critical whenever a long-term comparison of NDVI record is required.

Intercalibration of DMSP/OLS by Parallel Regressions

IEEE Geoscience and Remote Sensing Letters, 2016
The Defense Meteorological Satellite Program—Operational Linescan System night lights offer a unique data set, covering more than two decades. However, for a number of reasons, an intercalibration procedure has to take place in order to reduce year-to-year inconsistencies before a meaningful time series can be established.

An international intercalibration for mercury in seawater

Marine Chemistry, 1982
Abstract An intercalibration between 32 laboratories in 16 countries was conducted using acidified and ultraviolet-irradiated seawater. One sample was natural seawater but two were spiked with mercuric chloride, 15.4 and 143 ngl −1 , respectively. The results show, for the majority of the laboratories, good accuracy and precision in the recovery of ...

Intercalibration of 40Ar39Ar dating standards

Chemical Geology, 1996
A number of standards used for KAr and 40Ar39Ar dating have been intercalibrated. Multiple splits (∼ 15–40 mg each) of MMhb-1, SB-3 Biotite, LP-6 Biotite 40–60#, GA1550 Biotite, Fish Canyon Tuff-3 Biotite, Taylor Creek Rhyolite Sanidine, Bern 4 Muscovite, Bern 4 Biotite and Pennsylvania State University Orthoclase-1A were irradiated in capsules, fused

Phytobenthos Intercalibration - Rivers: Alpine Geographical Intercalibration Group: Final Report

2007
One of the key actions identified by the WFD is to carry out a European benchmarking or intercalibration (IC) exercise to ensure that good ecological status represents the same level of ecological quality everywhere in Europe (Annex V WFD).

Intercalibration of AVHRR and ATSR data

Advances in Space Research, 1996
Abstract The characterization of the AVHRR and ATSR instrument's relative performances and the intercalibration of their data products has been carried out. The intercalibration of two different infrared sensors shall be planned as an operational exercise in the future with automatic software tools.
