particle number concentration: The number of particles present in a given volume of air.
particle size distribution: The relative, size sorted number of particles present in a given volume of air.
pitch: The rotation of an aircraft or spacecraft about the horizontal axis normal to its longitudinal axis (in the along-track direction) so as to cause a nose-up or nose-down attitude.
pixel: Picture element. A single element of a digital image data set.
photo response non uniformity: Variation in sensitivity of pixels of a detector concerning a stable, homogeneous light source.
point spread function (PSF): The inferring of spatial characteristics of the instrument from the collected image of a point source such as a star.
polarization: The polarization describes the orientation of oscillations of waves and is an attribute of light.
pre-processing: Commonly used to describe the correction and processing of sensor data prior to information extraction.
protocol: A predefined procedural method in the design and implementation of experiments.
pushbroom: A method of taking remote sensing data by composing an image of information taken by line scanners.
