Areal distribution of monthly mean air temperatures in Fennoscandia (1921-1950)
Mean temperature maps and corresponding station values for each month of the year are presented. Mean temperatures are reduced to sea level, to rural conditions, to conditions with no lake influence, to conditions prevailing at low‑lying sites and to conditions under which local factors and errors c...
