	MOPITT Overview (Site not responding. Last check: 2007-10-08)
		MOPITT is a nadir sounding instrument since this gives the maximal chance of avoiding cloud features, but this implies that it can "see" the surface of the planet and the desired signals must be seen against the background of the surface radiation.
		The field-of-view of MOPITT is 22 x 22km and it views four fields simultaneously by the use of a 4 x 1 array of detector elements.
		The MOPITT instrument makes use of the principle of correlation spectroscopy whereby a cell of the gas to be measured is used as an optical filter in the infra-red to measure the signal from the same gas in the atmosphere.

		MOPITT measures the temporal and spatial distribution of carbon monoxide (CO) and methane (CH4) in the troposphere [the troposphere extends from the surface to approximately 15 - 17 km in the tropics and 7-12 km in the high latitudes].
		The MOPITT instrument is a multi-channel, nadir (downward) viewing correlation spectrometer which measures upwelling radiation in 3 wavelengths.
		In support of the MOPITT validation the NOAA/CMDL carbon cycle group is measuring vertical profiles of the 3 most abundant carbon gases (CO, CH4, and carbon dioxide (CO2)) at 6 locations around the world (Alaska, Colorado, Massachusetts, Hawaii, South Africa, and the Cook Islands).

	EO Newsroom: New Images - MOPITT First Light Image
		MOPITT measures radiances in several channels to determine the amount of carbon monoxide (CO) and methane in the atmosphere.
		Channel 1 Difference radiances, shown here, are sensitive to the temperature of the earth's surface, the temperature of the atmosphere, and the amount of CO Of these, the first two effects dominate.
		To recover the amount of CO, it is necessary to combine difference measurements like these with other MOPITT measurements of the radiation from the earth's surface, and independent data on the atmospheric temperature, to remove these effects and get at the subtle effects of CO. This effort is now underway.

	MOPITT to measure carbon monoxide in atmosphere
		Called MOPITT (Measurements of Pollution in the Troposphere), the instrument could provide new insight into the chemical complexity and dynamic variability of the lower atmosphere, where weather evolves and humans routinely disturb the environment.
		Its lifetime of two months is long enough for the gas to be tracked as it rises from the surface and journeys around the globe, yet short enough to prevent it from mixing evenly in the atmosphere, which would obscure its sources and paths.
		MOPITT will also measure methane, which rises into the air from far northern wetlands and subtropical rice paddies, as well as from cows, sheep, termites, natural gas leaks, and other sources.

	CSA - MOPITT: Measuring pollution changes
		Now, a Canadian space instrument named MOPITT (for “measurement of pollution in the troposphere”) is producing high-resolution 3-D maps that measure carbon monoxide levels around the globe.
		During 2003, when a massive number of fires were burning in Western Canada, MOPITT was able to quantify the amount of carbon monoxide in the atmosphere with the scale of the burning.
		By combining MOPITT data with local ground observations and measurements from balloons and aircraft, scientists are identifying pollution increases or decreases in specific regions.

		MOPITT is an infrared radiometer designed to measure carbon monoxide (CO) and methane (CH4) total column concentrations, and CO vertical profile concentrations.
		As part of the overall MOPITT data validation program, an aircraft version of the MOPITT (MOPITT-A) instrument was designed and built using many of the MOPITT development parts.

	MOPITT, launched at last, needs one more nudge
		MOPITT evolved out of conversations between James Drummond (University of Toronto) and John when Drummond was at NCAR on sabbatical in 1987.
		To sense the lowest levels of the troposphere, Drummond developed a new device, MOPITT's length modulator; John did some calculations with Beiying Wu, a visitor from the Chinese Academy of Sciences, to demonstrate that the technique had the required sensitivity, and the two then determined the gas pressures required within the instrument.
		MOPITT data will be assimilated into ACD's comprehensive atmospheric chemistry model, MOZART, to build a global picture of source regions and transport of CO as well as methane.

	MOPITT acceleration sensor as Piezoelectric Particle Detector
		The accelerometer sensors attached to the MOPITT cooler show occasional high level signals (single events) when Terra spacecraft passes over the South Atlantic Anomaly (SAA) region and the Polar region.
		Moreover, it is also demonstrated that major Solar Particle Events also induce a high daily rate of MOPITT device single events (DSE) when the high-energy component (>100 MeV) of the solar proton flux reaches a large value.
		These MOPITT DSEs are, as expected, located at the Polar Regions.

		Satellite observations of carbon monoxide (CO) from the Measurement of Pollution in the Troposphere (MOPITT) instrument were combined with measurements from the TRACE-P aircraft mission over the northwest Pacific, and with a global 3-D chemical transport model (GEOS-CHEM), to examine Asian pollution outflow and its transpacific transport during spring 2001.
		MOPITT observations provide greater information towards geographically disaggregating source regions within Asia in comparison to the aircraft observations, reflecting the ability of the satellite to observe all outflow and source regions.
		The MOPITT and TRACE-P observations are independently consistent in the constraints that they provide on Asian CO sources, where biomass burning emissions are much less than previously thought and emissions from small industrial coal facilities in China have been underestimated.
