Icelandic temperature series - temperature averages as originally published Supplemetary information on data published before 1961 The file consists of monthly temperature averages as published in the yearbooks of the Danish Met. Institute 1873 to 1919, the yearbook of the Icelandic Met. Office (IMO) 1920 to 1923 and the monthly climate summary published by the IMO after that. These sources are available online in pdf-format - individual pages - under their original names at: timarit.is Meteorologisk Aarbog 1873 - 1919 text in Danish and French http://timarit.is/view_page_init.jsp?pubId=241&lang=is Íslensk veðurfarsbók 1920 - 1923 text in Icelandic and French http://timarit.is/view_page_init.jsp?pubId=240&lang=is Veðráttan 1924 - 1960 text in Icelandic only http://timarit.is/view_page_init.jsp?pubId=278&lang=is Post 1961 averages are available in table format under the respective station names: http://en.vedur.is/climatology/data/ The files: original_pub_temperature_values.txt Temperature values in °C with one decimal, the period (.) is a decimal delimiter, ; is a column separator and NA indicates that no value is available for the particular month. Table headings: station id year Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec annual location : If station was relocated in the period each successive relocation adds one to the column number. screen : 1 = free standing icelandic screen 2 = northern wall mounted screen original_pub_temperature_stat_info.txt station id,lat (N),lon (W),height above sea level (m),name Note that only one location is listed per station - they are not to be considered to be exact to the decimal regarding the measurements in the file. Major homogeneity issues: Relocations (no corrections applied in the dataset) Screen type (no corrections applied in the dataset) Averaging practices (there was a major change in averaging practices in 1956. In the present dataset this has not been accounted for). Reading schedules (at most stations there have been some changes in the reading schedule - most of these do have some consideration in the dataset) Observer (no corrections applied in the dataset) All are important during the period in question. The IMO has calculated series with some appropriate adjustments for each individual station. The IMO generally uses the version with adjustments made on pre-1961 data rather than the present dataset. These data are available on request but the whole dataset will be made available later. It must, however, be emphasized that the adjustments will change in the future as more information on station history and inter-station comparison will be added. One should therefore expect changes in the adjusted dataset through time. The present dataset (original_pub_temperature_values.txt) will remain static, except for the addition of values from individual stations during the pre-1920 period which have not yet been digitized. Readers should note that these values are available in the Danish yearbooks already referred to. July 13 2012 Trausti Jónsson meteorologist
