The overarching objective of this comparison is “To establish the “degree of equivalence” between surface based IR Cal/Val measurements made in support of satellite observations of the Earths surface temperature and to establish their traceability to SI units through the participation of national standards laboratories”.
Objective is to identify and evaluate any biases between different participants in assigning a “radiometric value” to a test site.
These guidelines are intended to serve as guidance for the airborne in situ metric calibration of vertically oriented digital and film-based frame type cameras.
This document describes the procedure that should be followed to establish a new “reference test site” for the calibration and validation of radiometric gain of a land surface imager.
This is a “Best practice guide” to the characterisation of the properties of a land-based test-site, which impact on its radiometric use with optical remote sensors.
ISO/TS 19159-1:2014 defines the calibration and validation of airborne and spaceborne remote sensing imagery sensors.
