EUSTACE – Creating daily analyses of surface air temperature globally Climate Observations / Climate Observations - Explore / Explore / Projects & Initiatives - Climate Observations

Using surface skin temperature from satellites to estimate daily air temperature everywhere.

EUSTACE (EU Surface Temperature for All Corners of Earth) will give publicly available daily estimates of surface air temperature since 1850 across the globe for the first time by combining surface and satellite data using novel statistical techniques.

Day-to-day variations in surface air temperature affect society in many ways:

  • Health and well-being: it can cause cold stress or heat stress
  • Food security: link between surface air temperature and crop growth and animal health
  • Energy: influence on the demand for heating or cooling, high temperature compromise the efficiency of solar panels
  • Commerce: it affects the sales of a large variety of products
  • Tourism: it affects the attractiveness of a region, risk of bush fires
  • Infrastructure: extremes affect the functioning of bridges, railways

However, daily surface air temperature measurements are not available everywhere. Satellite data can be used to estimate temperatures at locations where no ground (or in situ) observations are available. To achieve this, we must develop an understanding of the relationships between traditional (land and marine) surface air temperature measurements and satellite measurements, i.e. land surface temperature, ice surface temperature, sea surface temperature and lake surface water temperature. These relationships can be derived either empirically, or with the help of physical understanding.

How will EUSTACE achieve this?
The EUSTACE project will use new statistical techniques to provide information on higher spatial and temporal scales than currently available, making optimum use of the information in data-rich eras. EUSTACE will undertake this work between January 2015 and June 2018. The final and intermediate products of EUSTACE (e.g. satellite skin temperature retirevals over all domains with consistent uncertainty estimates; station time series with discontinuities identified; information on the relationship between skin and air temperature over different domains and different seasons) will be interesting for many applications.
