Spatial resolution measurements of the advanced radiographic capability x-ray imaging system at energies relevant to Compton radiography

Not exact matches

The traditional methods used in materials science analysis, like high - powered electron microscopy and spectroscopy, do not combine chemical insights with the spatial resolution of IR imaging, the researchers said, so they can only provide average chemical measurements.

By extending their method to include Raman imaging, the RUB team achieved a higher spatial resolution than they could with infrared imaging, however, at the cost of prolonged measurement time.

The satellites give temperature measurements with a spatial resolution of roughly 1 square kilometre, which the team matched up with data from the US Federal Aviation Administration on the exact location of 2358 wind turbines in west - central Texas.

Liming Zhou of the University at Albany, State University of New York, and colleagues studied land - surface temperature data gathered by NASA's Terra and Aqua satellites, which give measurements with a spatial resolution of roughly 1 square kilometre.

The OCO mission aimed to make unique and high quality measurements of the atmospheric column of carbon dioxide at high spatial resolution.

The main strength of the SIF measurements from OCO - 2 relies on their very high spatial resolution.

One approach is to develop empirical regional models that enable aragonite saturation state to be estimated from existing hydrographic measurements, for which greater spatial coverage and longer time series exist in addition to higher spatial and temporal resolution.

This product is consistent with broad current knowledge about the surface sources and sinks of CO2, CH4 and N2O, but, to our knowledge, it is unique in its combination of temporal coverage, spatial resolution and inclusion of recent measurements.

These measurements are at high spatial resolution that can also be used to validate satellite data.

The principal scientific objective is to make global SSS measurements over the ice - free oceans with 150 - km spatial resolution, and to achieve a measurement error less than 0.2 (PSS - 78 [practical salinity scale of 1978]-RRB- on a 30 - day time scale, taking into account all sensors and geophysical random errors and biases.Salinity is indeed a key indicator of the strength of the hydrologic cycle because it tracks the differences created by varying evaporation and precipitation, runoff, and ice processes.

Several recent method developments improve the spatial and / or temporal resolution of CH4 ebullition measurements in lakes and reservoirs.

Although we did not explicitly address the temporal or spatial resolution of emission data from each system, it is notable that the few published acoustic and eddy covariance - based reservoir CH4 flux estimates are quite high compared to the median CH4 flux estimates from less temporally and / or spatially integrated measurement techniques (figure 1).

Satellite radiometric soundings have also been used to provide temperature readings in layers in the atmosphere from near the surface up to about 25 km (16 miles) or so, although these measurements offer less vertical and spatial resolution than in situ measurements.

Another avenue for monitoring is satellite measurements of column inventories of the gases, which provide much more detailed spatial coverage but no vertical resolution, in which air masses at different altitudes may carry gases that originated from different parts of the Earth's surface.

Loss of high spatial resolution would have a detrimental effect on measurements of all parameters, including sea ice, snow cover, and precipitation.

Some participants noted that even though a descoped OMPS on NPOESS will continue total - column ozone measurements, the OMPS - Nadir sensor lacks the state - of - the - art capability for measuring other trace species and for high spatial resolution, both of which are essential for advancing atmospheric research in the future.

QuikSCAT measurements are also limited to a spatial resolution of 12.5 km and are not routinely made closer than about 30 km from land.26 Many in the microwave breakout group argued that high priority should be given to a sustained, more capable, next - generation scatterometer program that can meet these requirements while at the same time continuing the ocean surface vector winds CDR established by QuikSCAT.

The disadvantage of a QuikSCAT clone is that some of the most important NOAA operational requirements established at the June 2006 NOAA Operational Ocean Surface Vector Winds Requirements Workshop27 would not be met (e.g., measurements of extreme winds, higher spatial resolution, and reduced contamination from rain and land).

These high - resolution measurements offer great potential for future investigations into the mechanics of aquifer systems and the spatial heterogeneity of aquifer system structure and material properties as well as for monitoring ongoing aquifer system compaction and land subsidence.
