| Sumario: | Abstract: A climate analysis of the monthly mean temperatures of Southern Patagonia during the late-
XIXth and early-XXth centuries was carried out as part of the international data rescue Atmospheric
Circulation Reconstructions over the Earth (ACRE) program partnership in Argentina, together
with other data sources with regional and global records. The data from these diverse sources were
combined to carry out a study in the coastal region of Patagonia, including Tierra del Fuego, between
42◦ S and 55◦ S for 11 locations. Furthermore, HadSST monthly/seasonal fields during the period
1880–1920 were also used. Both mean monthly and seasonal temperature values and timeseries
variability were considered. Their analysis shows consistent behavior within the study region and
compared to Southern Hemisphere mean results, which are characterized by a warm late-XIX century
and a cooler early-XX century. This is also in agreement with SST variability along the coasts of
Patagonia and hemispheric records. A comparison with present-day observations, where available,
also yields consistent behavior. Low-frequency variability, i.e., in periods longer than 3 years, during
the study period is consistent with present variability. Trend estimates at Trelew and Rio Gallegos for
the period 1901–2020 yield significant trends, consistent with hemispheric warming at their latitudes. |
