The aim of this chapter is to give an overview of the techniques used to observe the atmosphere, and the physical principles involved. In particular, we attempt to highlight characteristics of different observation types that need to be taken into account when using them in an atmospheric data assimilation system.

Atmospheric turbulence and surface atmospheric electricity observations
2004Durable and low maintenance atmospheric electricity sensors are required if measurements which span long (year to decade) timescales are to be obtained. A passive spherical sensor, together with a high impedance electrometer, presents one method of monitoring the vertical Potential Gradient at the surface.

Satellite Observations of Atmospheric Water Vapor
Applied Optics, 1974Observations in the spectral window at 11-12 microm, in the carbon dioxide band at 13.3-13.4 microm, and in the water vapor rotation band at 18.7-18.8 microm have been made by the satellite infrared spectrometer and the vertical temperature profile radiometer on the Nimbus 4 and NOAA-2 satellites.

Mid-ocean observations of atmospheric radiation
Quarterly Journal of the Royal Meteorological Society, 1979AbstractMid‐ocean (35°N 155°W) observations of the various components of radiative flux were made from the R/P FLIP during the period 2 through 13 February 1974. Cloud cover ranged from clear skies to overcast, and water vapour pressure varied between 9 and 18 mb, with sea surface temperature near 15.0°C.The net longwave radiative fluxes reported here ...

Titan's atmosphere from voyager infrared observations
Icarus, 1989Abstract We have studied the 900–1200 cm−1 range in three different selections of ∼30 Voyager 1 IRIS spectra recorded in Titan's equatorial region. In particular, we have reanalyzed the 8.6-μm emission feature attributed to both C3H8 and CH3D bands. Observations were compared to synthetic spectra generated from an atmospheric model which incorporates

Observing Through Atmospheric Turbulence
2010Astronomical observations from the ground are limited in sensitivity – not so much in performance – by atmospheric turbulence. Removing the sensitivity limit by observing a reference star close to the object of interest, to freeze the turbulence and to permit long integration times, one is then restricted to a small field of less than 1 arcmin around ...

Atmospheric physics and Earth observations: atmospheric spectral imaging.
Science (New York, N.Y.), 2010An array of imaging spectrometers flown on the Spacelab 1 mission was capable of providing spectra of the atmospheric emissions over a broad wavelength range from 300 to 12,700 angstroms and acquiring each complete spectrum nearly simultaneously. The instrument was used to make observations on the day side and night side of the earth, looking down in ...
