calibration (cal): The process of determining values and accuracies to sensor parameters allowing a comparison of sensor measurements with reference values.
calibration data: In remote sensing, measurements pertaining to the spectral or geometric characteristics of a sensor or radiation source.
campaign: Realization of several surveys within a given time period.
channel: A channel is the abundance of data containing one spectral sensitive wavelength range of the sensor acquired during a specific time period and represents a two dimensional array of data with a spatial and time dimension.
COPAL: COmmunity heavy-PAyload Long endurance instrumented aircraft for tropospheric research in environmental and geo-sciences.
COPERNICUS: Copernicus, previously known as GMES (Global Monitoring for Environment and Security), is the European Programme for the establishment of a European capacity for Earth Observation.
coverage: Total area of the Earth surface that can potentially be mapped within a given time frame.
cross-calibration: The comparison of one sensor to another sensor on different aircraft.
characterization: The process of determining parameters of a sensor or sensor system necessary to operate it in a given environment and interpret its measurements.
