Sentences with phrase «radiosonde network»

You can easy pick out the radiosonde network from this type of image.

Another point: the reanalysis datasets are anchored to the radiosonde network especially where the density of such observations is high.

Almost 50 years ago, the Quasi-Biennial Oscillation (QBO) of the winds in the equatorial stratosphere was detected due to the establishment of a global, regularly measuring radiosonde network (Graystone, 1959; Ebdon, 1960).

The radiosonde network has been around for over 50 years, and typically most operational forecast NWP models as well as reanalysis models treat the raobs similarly.

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.

Balling & Cerveny (2003) using the US radiosonde network, find a statistically significant inverse correlation between GCR flux and low cloud cover over the continental United States.

It is of course possible that the observed humidity trends from the NCEP data are simply the result of problems with the instrumentation and operation of the global radiosonde network from which the data are derived.

NOAA's own radiosonde network shows no warming.

The radiosonde network has been operative since the late 1940s and substantialcontinue

This may partly be due to the coverage of sondes used in that analysis being biased to the high latitudes (since the effect of the error was principally in the tropics), or it may be because of undetected biases in the radiosonde network itself.

The «global» reference radiosonde network is embarrassing small.

First off, Lanzante and Free do an excellent job in really pinning down the biases (compared to satellites and models) of the standard homogenised radiosonde networks (RATPAC2 and HadAT2).

Not exact matches

«Using more recent data and better analysis methods we have been able to re-examine the global weather balloon network, known as radiosondes, and have found clear indications of warming in the upper troposphere,» said lead author ARC Centre of Excellence for Climate System Science Chief Investigator Prof Steve Sherwood.

Using U.S. Weather Service data on precipitation, radiosonde measurements of CAPE and lightning - strike counts from the National Lightning Detection Network at the University of Albany, State University of New York (UAlbany), they concluded that 77 percent of the variations in lightning strikes could be predicted from knowing just these two parameters.

One additional piece of evidence that has been discussed frequently was the claim that the trends in UAH MSU 2LT closely matched those of the radiosonde (balloon) network (Christy et al, 2003).

Temperatures aloft can be measured in a number of ways, two of which are useful for climate monitoring: by radiosondes (balloon - borne instrument packages, including thermometers, released daily or twice daily at a network of observing stations throughout the world), and by satellite measurements of microwave radiation emitted by oxygen gas in the lower to mid-troposphere, taken with an instrument known as the Microwave Sounding Unit (MSU).5 The balloon measurements are taken at the same Greenwich mean times each day, whereas the times of day of the satellite measurements for a given location drift slowly with changes in the satellite orbits.

Location of radiosonde stations in the World Meteorological Organization's (WMO) Global Observing System upper air network.

NCEP humidity information derives ultimately from the international network of balloon - borne radiosondes.

Meshing the radiosondes in a dense data network such as the US is much easier than figuring out the North Pacific without in situ surface obs or radiosondes.

Steve Sherwood, chief investigator for the ARC Centre of Excellence for Climate System Science and lead author for the study, explained that he and his colleague Nidhi Nishant used improved methods of analysis and more recent data to reexamine radiosondes, or the global weather balloon network.
