Parameter
type: Class
comment: A measured physical property in signal units. It has units and possibly a timestamp. The signal units are not the physical ones, like Gauss or Kelvin, but are something inherent in the detector, like volts or ADU's. The physical units are either calculated or inferred from the signal units.

Deployment
type: Class

comment: A platform is deployed during a certain duration of time and over a certain spacial domain. The platform has instruments on it within the scope of this deployment. For example, a boat will carry certain instruments during a deployment, and those instruments will be removed once the deployment is completed. A stationary deployment can last a much longer time, even decades, with the same instrument.

Instrument
type: Class
comment: A device that measures a physical phenomenon or parameter. At a minimum, it possesses a detector which produces a signal from which the desired quantity is calculated or inferred. The detector signal possesses the information needed to either obtain the value of the phenomenon (e.g, temperature: a voltage is converted into a temperature unit) or infer its value using further processing and computation (magnetic fields: detector intensities at a different wavelengths and polarization states are processed to infer a magnetic field strength). An instrument does not necessarily require a way to store its measured quantity (e.g, a hard disk).

Febry Perot Interferometer
type: Class
subclass of: Interferometer
comment: A multiple-beam interferometer, usually consisting of two flat plates, with high reflective ability. The plates are set parallel to one another by spacers so that light waves may bounce back and forth between them several times. The requirements for constructive interference of reflected light waves of a given wavelength can be fulfilled only at particular angles, relative to the normal to the plates. Therefore, Fabry-Perot interferometers can be used as spectrometers with high resolution. Used as a laser resonator, the Fabry-Perot reinforces only light of specific frequencies traveling perpendicular to the mirror surfaces, and its successive reflections and amplifications form the oscillating mode.

has super physical domain: EarthAtmosphere
has minimum altitude in km: 5.5E2
has name: Earth Exosphere
has maximum altitude in km: 8.0E2

EarthTroposphere
type: Atmosphere Layer
comment: From the Greek word "tropos" meaning to turn or mix. The troposphere is the lowest layer of the atmosphere starting at the surface going up to between 7 km at the poles and 17 km at the equator with some variation due to weather factors. The troposphere has a great deal of vertical mixing due to solar heating at the surface. This heating warms air masses, which then rise to release latent heat as sensible heat that further buoys the air mass. This process continues until all water vapor is removed. In the troposphere, on average, temperature decreases with height due to expansive cooling.
