{{Atmospheric sciences}}

Over the last two centuries many environmental '''chemical observations''' have been made from a variety of ground-based, [[aircraft|airborne]], and [[Orbital spaceflight|orbital]] platforms and deposited in [[databases]]. Many of these [[databases]] are publicly available. All of the instruments mentioned in this article give online public access to their data. These observations are critical in developing our understanding of the [[Earth's atmosphere]] and issues such as [[climate change]], [[ozone depletion]] and [[air quality]]. Some of the external links provide repositories of many of these datasets in one place. For example, the Cambridge Atmospheric Chemical Database, is a large [[database]] in a uniform [[ASCII]] format. Each observation is augmented with the meteorological conditions such as the [[temperature]], [[potential temperature]], [[geopotential height]], and equivalent [[Potential vorticity|PV]] latitude.

* '''ATMOS observations'''. The [http://remus.jpl.nasa.gov/atmos/atmos.html Atmospheric Trace Molecule Spectroscopy] experiment (ATMOS) is an infrared spectrometer (a Fourier transform interferometer) that is designed to study the chemical composition of the atmosphere. In this section you will be able to read both general and detailed information as to why and how the instrument works. The ATMOS instrument has flown four times on the Space Shuttle since 1985. The predecessor to ATMOS, flown on aircraft and high-altitude balloon platforms, was born in the early 1970s out of concern for the effects of Super Sonic Transport exhaust products on the ozone layer. The experiment was redesigned for the Space Shuttle when the potential for ozone destruction by man-made chlorofluorocarbons was discovered and the need for global measurements became crucial.

* '''CRISTA observations'''. [https://archive.istoday/20011201094454/http://www.crista.uni-wuppertal.de/introduction.shtml CRISTA] is short for CRyogenic Infrared Spectrometers and Telescopes for the Atmosphere. It is a limb-scanning satellite experiment, designed and developed by the [[University of Wuppertal]] to measure infrared emissions of the Earth's atmosphere. Equipped with three telescopes and four spectrometers and cooled with liquid helium, CRISTA acquires global maps of temperature and atmospheric trace gases with very high horizontal and vertical resolution. The design enables the observation of small scale dynamical structures in the 15–150 km altitude region.
