Monthly weather averages for Palmer Station, Antarctica (1974-2024)

A long-term timeseries of monthly averaged weather at Palmer Station, Antarctic, was created by combining calculated averages of daily weather from 1989-present with additional historical temperature measurements made between 1974-1989. The selected variables in this dataset include temperature, air pressure, precipitation, sea surface temperature, and wind speed. Monthly averages (means) are made for each calendar month, and dated with the month's start date. Historical monthly average temperatures (through March 1989) are from "Baker, K.S. (1996), Palmer LTER: Palmer Station air temperature 1974 to 1996." Monthly averages from April 1989 onwards are computed from the daily weather averages calculated at Palmer Station and made available by the Antarctic Meteorological Research Center (AMRC) archive at https://amrdcdata.ssec.wisc.edu/group/palmer-station/ The daily averages are available in aggregate form as PAL dataset #28 (knb-lter-pal.28.10), from which this dataset was generated.本数据集为南极帕尔默站（Palmer Station）的长期逐月平均气象时间序列，整合了1989年至今的逐日气象计算平均值与1974-1989年间的历史气温观测数据。本数据集包含的气象变量包括气温、气压、降水量、海表温度及风速。所有月平均值均针对自然月计算，数据时间戳采用对应月份的首日。1989年3月及之前的历史月均气温数据引自文献《Baker, K.S. (1996), Palmer LTER: 1974-1996年帕尔默站气温》。1989年4月起的月平均数据，由南极气象研究中心（Antarctic Meteorological Research Center, AMRC）归档的帕尔默站逐日气象平均值计算得到，相关数据可通过以下网址获取：https://amrdcdata.ssec.wisc.edu/group/palmer-station/。本数据集的原始逐日平均数据以聚合形式存储为PAL数据集#28（编号knb-lter-pal.28.10），本数据集即基于该数据集生成。
