Sentences with phrase «resolution radiosonde data»

Not exact matches

Although modern remote sensing by satellites, aircraft and ground sensors is an increasing source of atmospheric data, none of these systems can match the vertical resolution (30 m (98 ft) or less) and altitude coverage (30 km (19 mi)-RRB- of radiosonde observations, so they remain essential to modern meteorology.

Long - term continuity of the radiosonde network is needed for assessing changes in water vapor, providing data with good vertical resolution, and evaluating remotely sensed water vapor fields.

To date, most large - scale water vapor climatological studies have relied primarily on analysis of radiosonde data, which have good resolution in the lower troposphere in populated regions but are of limited value at high altitude and are lacking over remote oceanic regions.

Prior to 1988, the satellite data that Trenberth uses is not available, but it is known that long term records in radiosondes contain large inhomogeneities due to improving observing systems, increasing spatial resolution (but still very little ocean coverage), and the NCEP data in particular contains large model biases.
