[{"name":"tarfala-kirchner-2023-monthly-temperature-1","title":"Monthly mean air temperatures from Tarfala Research Station, Kebnekaise Mountains, 1965\u200a\u2013\u200a2022","summary":"This dataset contains monthly mean air temperatures from Tarfala Research Station, acquired since 1965 and updated annually. For the years 1946\u200a\u2013\u200a1964, monthly averaged June, July and August air temperatures are reported. The dataset therefore provides important climatological information in itself, and also context for a wide range of other climate system components in the Tarfala Valley, such as glaciers, streams, permafrost, etc., and their dynamic change over time. \r\n\r\nThe instrumentation with which air temperatures were acquired has varied over the years. The most recent instrumentation is described below. For older instrumentation, references to the literature describing the instrumentation is cited. \r\n\r\nParts of this dataset have been published previously (for links, see below), however, the present dataset is the first comprehensive one, collecting all data in one file at one location.  Importantly, this dataset contains also previously unpublished data from the year 2014, and from the years 2021 onward.\r\n","citations":"Grudd, H., & Schneider, T. (1996).

Excluding the years for which data is partially missing (2009, 2022), annual averages temperature was lowest in 1966 (-5.9 \u00b0C), and warmest in 2016 (- 1.7 \u00b0C). The summer season \u2013 June, July, August \u2013 was coldest in 1975 (3,3 \u00b0C) and warmest in 2002 (8,7 \u00b0C). Mean July temperatures have been above 10 \u00b0C in the years 2003 (11,7 \u00b0C), 2014 (12,6 \u00b0C), 2018 (12,8 \u00b0C)  and 2021 (10,2 \u00b0C): This is of interest as one of the definitions of \u201cArctic\u201d is that July average temperatures do not exceed 10 \u00b0C.
