Multi-Instrument Inter-Calibration (MIIC) System

Remote Sensing, 2016
In order to have confidence in the long-term records of atmospheric and surface properties derived from satellite measurements it is important to know the stability and accuracy of the actual radiance or reflectance measurements.

Opportunistic Constant Target Matching—A New Method for Satellite Intercalibration

Earth and Space Science, 2020
Opportunistic constant target matching is a new method for satellite intercalibration. It solves a long‐standing issue with the traditional simultaneous nadir overpass (SNO) method, namely, that it typically provides only data points with cold brightness

Stability of the Nine Sky Quality Meters in the Dutch Night Sky Brightness Monitoring Network

Sensors, 2015
In the context of monitoring abundance of artificial light at night, the year-to-year stability of Sky Quality Meters (SQMs) is investigated by analysing intercalibrations derived from two measurement campaigns that were held in 2011 and 2012.

A comparison of sulphur analysis of conifer needle samples

Silva Fennica, 1989
The results of an intercalibration of sulphur analysis by 24 laboratories are evaluated. The analysis was made by one or more of six methods. The following three methods were found to be satisfactory as regards relative speed and reliability: Leco S ...

Training and intercalibration reduce observer-induced variability in forest vegetation surveys [PDF]

Vegetation Ecology and Diversity
The increasing availability of vegetation-plot data results from decades of field surveys conducted by numerous observers. This highlights observer error not as a marginal issue but as a structural component of uncertainty, with direct consequences for ...
