Sentences with phrase «land surface air temperature data»
This is likely caused, in part, by GISS masking sea surface temperature data in the polar oceans and replacing it with land surface air temperature data, which is naturally more volatile.

They then infill the Arctic and Southern Oceans with land surface air temperature data.
Not exact matches
For their paper, published in Applied Geography, researchers at the Earth Institute at Columbia University and Battelle Memorial Institute studied air temperature data from weather stations, land surface temperatures measured by satellites and socioeconomic data.
So the infilled GISS data, which extends out over the Arctic, would show the greater warming since the 1970s... until the warming stops for Northern Hemisphere sea surface temperatures and for the low - to - mid latitude land surface air temperatures.
The hybrid method used by Cowtan and Way (2013) fills in missing data (both land air and sea surface temperature) using lower troposphere temperature data from UAH.
It's hard to imagine how Cowtan and Way could determine with any degree of certainty how «the hybrid method works best over land and most importantly sea ice» when there is so little surface air temperature data over sea ice.
These issues, which are either not recognized at all in the assessments or are understated, include: - the identification of a warm bias in nighttime minimum temperatures - poor siting of the instrumentation to measure temperatures - the influence of trends in surface air water vapor content on temperature trends - the quantification of uncertainties in the homogenization of surface temperature data, and the influence of land use / land cover change on surface temperature trends.
HadSST3, HADISST and ERSST.v3b, all include bucket model adjusted ICOADS data, and HADCRUT4 is «a blend of the CRUTEM4 land - surface air temperature dataset and the HadSST3 sea - surface temperature (SST) dataset.»
The surface data (left panel) are comprised of surface air temperature over land and the temperature of water at the ocean's surface, and have been subjected to a slight additional smoothing to simplify the pattern (Jones et al., 1999).
To clarify, land temperature anomalies are recorded as surface air temperature, but ocean temperature records are a more complex function that I believe also incorporates data from the water surface itself.
«Causes of differences in model and satellite tropospheric warming rates» «Comparing tropospheric warming in climate models and satellite data» «Robust comparison of climate models with observations using blended land air and ocean sea surface temperatures» «Coverage bias in the HadCRUT4 temperature series and its impact on recent temperature trends» «Reconciling warming trends» «Natural variability, radiative forcing and climate response in the recent hiatus reconciled» «Reconciling controversies about the «global warming hiatus»»
Figure 2.4 (Folland et al., 2001) shows simulations of global land - surface air temperature anomalies in model runs forced with SST, with and without bias adjustments to the SST data before 1942.
aaron, all three datasets start with the same source data: land surface air temperatures and sea surface temperatures.
NASA Earth Observatory images by Jesse Allen, using AIRS Land Surface Temperature data provided courtesy of the AIRS team.
Combining this data with surface air temperature over land would avoid the problem identified by Cowtan and Way.
Therefore, in contrast to the Jones et al. (2001) global land - surface air temperature data, the global land and sea surface temperature data are not a simple average of the hemispheres.
