Sentences with phrase «balloon radiosonde measurements»

Not exact matches

Millions of measurements taken by balloon - borne radiosondes do not show it.

That's why climate scientists release radiosonde balloons, mount scientific expeditions, launch satellites into orbit, drill into the ice, deploy ocean buoys, as well as make increasingly accurate surface measurements.

Temperature measurements retrieved from the hundreds of balloon - borne radiosonde instruments that are released each day by the various national weather services provide much more detailed information on the vertical structure of atmospheric temperature changes than is available from satellites.

The IPCC's gold - standard for upper troposphere data is the UK's HadAT2 dataset that represents high altitude balloon / radiosonde measurements.

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.

Because the satellite data measure an average temperature through a depth of several kilometres in the atmosphere, they would be expected to compare better with upper - air measurements taken using weather balloons and radiosondes than they would with measurements at the surface.

The most glaring may be that theory says that the troposphere will warm more rapidly than the surface, but estimates of tropospheric warming from satellites, corellated reasonably well with measurements from radiosonde balloons, show slower warming in the troposphere.
