Error analysis of air temperature profile retrievals with microwave sounder data based on minimization of covariance matrix of estimation error is conducted. Additive noise is taken into account in the observation data with microwave sounder onboard satellite. Method for air temperature profile retrievals based on minimization of difference of brightness temperature between model driven microwa...

One of the important features of the fiber-optic distributed temperature log is its ability to acquire continuous, instantaneous and simultaneous temperature profile along the entire wellbore. Series of successive temperature profiles sampled every one minute or so enable to analyze transient temperature phenomena, which may pertain to important reservoir properties. For example, when change of...

We have demonstrated the feasibility of depth and surface temperature measurements in active areas of semiconductor devices using confocal Raman spectroscopy. Using micro heaters, we created a 3D temperature profile across micron size volume. We determined the temperature profile with sub-micron resolution and obtained good agreement with calculations. Theoretical uncertainty in temperature det...

One of the most effective methods of reducing the impact of error due to acquired thermoelectric inhomogeneity of thermocouples' electrodes is discussed in this article. The method consists in stabilizing the profile of the temperature field along electrodes of the main thermocouple (which measures the temperature of the object). There is also discussed the design of device for profile stabiliz...

in recent years, extraction of atmospheric temperature and humidity profiles from thermal bands of satellite images is a common practice. the most deployed images for this task have been acquired by moderate resolution imaging spectroradiometer (modis). this sensor which is onboard of terra and aqua platforms consists of a spectroradiometer with 36 bands in visible (vis), near infra-red (nir) u...

Accelerometer measurements made by Spirit and Opportunity during their entries through the martian atmosphere are reported. Vertical profiles of atmospheric density, pressure, and temperature with sub-km vertical resolution were obtained using these data between 10 and 100 km. Spirit’s temperature profile is ∼10 K warmer than Opportunity’s between 20 and 80 km. Unlike all other martian entry pr...
