These were: the first day of ice break-up in Tallinn port a proxy for the mean winter air temperature (December to March); the first day of ice break-up on the rivers in northern Estonia a proxy for the beginning of spring; and the first day of the rye harvest a proxy for the mean air temperature in spring and summer (April to July). On the basis of these proxies the mean winter temperature could be extended back to the year AD 1500 and the spring and summer temperature back to 1731. true 2017-05-08T07:12:51Z 2457881.8005903 Eur 026.temperature Eur-Tallinn.Tarand.2001.paleo1measurement1 0 en Eur-Tallinn.Tarand.2001.paleo1measurement1 IncludesVariable (L) 102 en core:includesVariable|http://linked.earth/ontology# IncludesVariable (L)
