Data-sparse and extreme regions is the topic of the second year of the network, and of the second workshop (12-14 June 2013, Copenhagen). A focus is the high-latitude domains, but the network remains inclusive and open to surface temperature researchers of all backgrounds who are interested in sharing knowledge and making connections across sub-discipline boundaries.

The workshop facilitated the collaborations between researchers and had substantial dialogue and networking activities as well as invited overview presentations, panel discussions and the opportunity to present participants' work in poster sessions.
