Sentence examples for the proxy data from inspiring English sources

What is the proxy data used in your studies and why is it being challenged?

The proxy data were first standardized individually, and then the average was calculated to present regional temperature variations.

Generally, the proxy data networks become sparser back in time and the reconstructed variance is increasingly sensitive to the influence of individual proxy records.

where the annual summer irradiance (I) was reconstructed from the proxy data of mean δ13C chronology in the same year (t).

The modelling results also present a strong positive correlation between temperature and salinity south of Iceland and solar irradiance (Fig. 3a, b), although the hydrographic variability in the model is of smaller amplitude than in the proxy data.

We note that the proxy data approach is already well-established as a technique for assessing the long-term risk from radiation storms, but does not yet provide any means to assess the risk from severe geomagnetic storms.

Meteorological station data rather than CRU were used for the proxy-data screening because we found the tree-ring proxy records have a higher cross-correlation with near-by station data.

The regional average temperature reconstruction over the period 801 2000 CE is tested as robust against changes in the proxy-data network and methodology (the Pearson correlation coefficients are higher than 0.86 between the BHM and the composite reconstructions; see the Methods section for more details).

After an episode of decline between 22,000 and 20,000 14C yr B.P. and an episode of rebound between 20,000 and 18,600 14C yr B.P., the paleolakes started to desiccate and completely disappeared around 18,000 14C yr B.P. The environmental proxy data indicate that the Megalake Tengger formed under warm humid climates.

The δ13C proxy data suggests an abrupt reduction in irradiance in AD 536, with even a more prolonged anomaly after the second eruption.

No one was recording the influx of GRCs or SEPs back then, so the researchers use proxy data taken from the composition of ancient ice cores dug up at the poles.
