Trace gas retrieval including horizontal gradients

Advances in Space Research, 2002
Abstract The development of a software package for the retrieval of vertical trace gas profiles from limb sounding measurements led to the analysis of the radiometric effects of inhomogeneous distributions of pressure, temperature and/or trace gases within simulated atmospheric layers as seen by a limb sounding instrument.

Pressure gradient in horizontal liquid–liquid flows

International Journal of Multiphase Flow, 1999
Summary: Pressure gradients were measured during the cocurrent flow of a low viscosity oil (1.6 mPa s viscosity and 801 \(kg/m^{3}\) density) and water in two 1-inch nominal bore horizontal test sections made from stainless steel and acrylic resin, respectively.

The effect of horizontal gradients on thermohaline convection

Journal of Fluid Mechanics, 1969
When the vertical boundaries of a container of stratified brine solution are heated, cells are observed to form in the brine with a layered structure. An explanation of this phenomenon has been given in terms of the successive growth of cells from the top and bottom of the container.

Temperature gradients in horizontal tube furnaces

Thermochimica Acta, 1986
Abstract Radial temperature differences in a 1 in. diameter horizontal tube furnace similar to those used in thermogravimetry were measured as a function of purge gas flow rate and pressure at temperatures from 25 to 525°C. The temperature difference between a thermocouple at the tube axis and one 0.8 cm off center was 45°C at 400°C, 1 atm pressure ...

Langmuir turbulence in horizontal salinity gradient

Ocean Modelling, 2018
Abstract Langmuir circulation (LC) is believed to be one of the leading causes of turbulent mixing in the upper ocean. Large eddy simulation (LES) models that solve the Craik–Leibovich equations are used to study LC in the upper ocean, yielding new insights that could not be obtained from field observations or turbulent closure models alone.

Horizontal gradient polyacrylamide gel electrophoresis

ELECTROPHORESIS, 1981
AbstractA simple Technique for horizontal gradient polyacrylamide gel electrophoresis (PAGE) in discontinuous buffer systems is described, in which one‐dimensional, two‐dimensional and double one‐dimensional separation patterns can be obtained. The advantages of this technique are: (i) that samples can be applied by overlaying on a variable broad area ...

Frontogenesis in a fluid with horizontal density gradients

Journal of Fluid Mechanics, 1989
The adjustment under gravity of a fluid containing a horizontal density gradient is described.’ The fluid is initially at rest and the resulting motion is calculated as the flow accelerates, driven by the baroclinic density field. Two forms of the initial density distribution are considered. In the first the initial horizontal gradient is constant.

A Note on Horizontal Gradients in Fjords

Journal of Physical Oceanography, 1977
Abstract Observations from the Oslofjord show that the transverse gradients of temperature and density are of the same order of magnitude as those in the longitudinal direction of the fjord. A comparison between current measurements and computed geostrophic current shows good agreement.

Automated interpretation of horizontal magnetic gradient profile data

Geophysics, 1992
Abstract A new technique has been developed to estimate the vertical magnetic gradient (G z ) along a profile from measurements of the two orthogonal horizontal magnetic gradients (G x and G y ). In addition, a means of identifying two-dimensional anomaly sources and the angle of the structure relative to the profile direction is ...
