Surface Temperature Corroborated By Satellites – Met Office 2013
By Paul Homewood
We are assured by the
crooks experts that the satellite temperature data must be wrong, as it keeps giving out the wrong message.
This is all very strange, because the Met Office’s Peter Stott told us only two years ago that changes in temperature observed in surface data records are corroborated by measurements of temperatures below the surface of the ocean, by records of temperatures in the troposphere recorded by satellites and weather balloons,
This backed up what the IPCC had said in their Fourth Assessment Report in 2007:
Lower-tropospheric temperatures have slightly greater warming rates than those at the surface over the period 1958 to 2005.
The radiosonde record is markedly less spatially complete than the surface record and increasing evidence suggests that it is very likely that a number of records have a cooling bias, especially in the tropics. While there remain disparities among different tropospheric temperature trends estimated from satellite Microwave Sounding Unit (MSU and advanced MSU) measurements since 1979, and all likely still contain residual errors, estimates have been substantially improved (and data set differences reduced) through adjustments for issues of changing satellites, orbit decay and drift in local crossing time (i.e. diurnal cycle effects). It appears that the satellite tropospheric temperature record is broadly consistent with surface temperature trends provided that the stratospheric influence on MSU channel 2 is accounted for. The range (due to different data sets) of global surface warming since 1979 is 0.16°C to 0.18°C per decade compared to 0.12°C to 0.19°C per decade for MSU estimates of tropospheric temperatures. It is likely, however, that there is slightly greater warming in the troposphere than at the surface, and a higher tropopause, with the latter due also to pronounced cooling in the stratosphere.
Woodfortrees comfirms that Hadcrut surface and RSS satellite data followed each other closely up to the end of 2005, as the IPCC reported.
This is not the first time that the climate establishment has attempted to discredit the satellite data. Last year, Katharine Hayhoe claimed in a CNN report that there were errors in troposphere data, which are commonly misused by climate skeptics. The link she gives refers to this NOAA report from as long ago as 2006:
Note that it states this significant discrepancy no longer exists because errors in the satellite and radiosonde data have been identified and corrected.Also that for recent decades, all current atmospheric datasets now show global-average warming that is similar to the surface warming.
We can expect these attacks to go on.
