The usefulness of global‐average diurnal temperature range (DTR) as an index of climate change and variability is evaluated using observations and climate model simulations representing unforced climate variability and anthropogenic climate change. On decadal timescales, modelled and observed intrinsic variability of DTR compare well and are independent of variations in global mean temperature. Observed reductions in DTR over the last century are large and unlikely to be due to natural… 
Evaluation of Historical Diurnal Temperature Range Trends in CMIP5 Models
AbstractDiurnal temperature range (DTR) is a useful index of climatic change in addition to mean temperature changes. Observational records indicate that DTR has decreased over the last 50 yr because
Complementary explanation of temperature response in the lower atmosphere
There are a number of asymmetries in the surface air temperature response to forcing, including polar amplification and changes to the diurnal and seasonal temperature ranges. We propose that such

Studying the global and regional climate variability and associated climatic impacts induced by different climate drivers (anthropogenic and natural climate forcings) is a subject of great interest
The long‐term trend in the diurnal temperature range over Asia and its natural and anthropogenic causes
Understanding the causes of long‐term temperature trends is at the core of climate change studies. Any observed trend can result from natural variability or anthropogenic influences or both. In the
The diurnal temperature range in the CMIP5 models
This paper analyzes the diurnal temperature range (DTR) over land in simulations of the recent past and in future projections by 20 models participating in the Coupled Model Intercomparison Project
Influence of increased greenhouse gases and sulphate aerosols concentration upon diurnal temperature range over Africa at the end of the 20th century
In order to investigate the diurnal temperature range response under enhanced greenhouse gases and sulphate aerosols concentrations over Africa, two ensembles of 19 integrations are conducted using
Decadal differences of the diurnal temperature range in the Aral Sea region at the turn of the century
Abstract Changes in the surface air diurnal temperature range (DTR) have been highlighted by the Intergovernmental Panel on Climate Change as critical uncertainties in climate change studies. Due to
Factors Contributing to the Spatial Variability of Satellite Estimates of Diurnal Temperature Range in the United States
TLDR
It is shown that the cooling effect due to transpiration from dense vegetation on land surface temperature (LST) is more evident during daytime than nighttime, which makes the difference between daily maximum and minimum LSTs or DTR decrease with vegetation; this is seen only during the growing season.
Diurnal temperature range in CMIP5 models and observations on the Tibetan Plateau
The diurnal temperature range (DTR), defined as the difference between the maximum and minimum temperature, is a useful diagnostic index for evaluating global climate models. In this study, the DTR

TLDR
Comparison of index trends in observations and model simulations shows that North American temperature changes from 1950 to 1999 were unlikely to be due to natural climate variation alone, while observed trends over this period are consistent with simulations that include anthropogenic forcing.
