[1] [2] The resulting temperature profiles depend on details of the methods that are used to obtain temperatures from radiances. As a result, different groups that have analyzed the satellite data have produced differing temperature datasets. The satellite time series is not homogeneous.
Data are provided as temperature anomalies against the seasonal average over a past basis period, as well as in absolute temperature values. The baseline period for the published temperature anomalies was changed in January 2021 from 1981-2010 to 1991-2020. [4] All the data products can be downloaded from the UAH server. [5]
They addressed this problem by combining the surface temperature measurements with satellite data to fill in the coverage. Over the time period 1979-2016, combining the HadCRUT4 surface data with UAH satellite coverage, they show a global surface-warming trend of 0.188 °C/decade.
The last 25 years of surface measurements with various averages and a comparison to El Niño and volcanic forcing. The surface temperature record extended back to 1880. (UAH 2003; data set tltglhmam version 5.2 with 2009 updates) and Schabel et al. (RSS 2002; data set tlt_land_and_ocean with 2009 updates). These two satellite records reflect ...
Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather, long-term climate change, natural disasters.
From 1989 this work proceeded in conjunction with the Met Office Hadley Centre for Climate Prediction and Research, and their work demonstrated global warming of almost 0.8 °C over the last 157 years. [8] Access to weather station temperature records was often under formal or informal confidentiality agreements that restricted use of this raw ...

RSS is a widely cited source of data on the satellite temperature record.Their data is one source of evidence for global warming.Research by Carl Mears, Matthias Schabel, and Wentz, all of RSS, highlighted errors in the early satellite temperature records compiled by John Christy and Roy Spencer at UAH, [1] [2] which had previously showed no significant temperature trend, bringing the derived ...
