Abstract. The CRUTEM4 (Climatic Research Unit Temperature, version 4) land-surface air
temperature data set is one of the most widely used records of the climate
system. Here we provide an important additional dissemination route for this
data set: online access to monthly, seasonal and annual data values and
time series graphs via Google Earth. This is achieved via an interface
written in Keyhole Markup Language (KML) and also provides access to the
underlying weather station data used to construct the CRUTEM4 data set. A
mathematical description of the construction of the CRUTEM4 data set (and its
predecessor versions) is also provided, together with an archive of some
previous versions and a recommendation for identifying the precise version
of the data set used in a particular study.
