Fisher Meteorological Station at Harvard Forest since 2001

The Fisher Meteorological Station became operational on 11 Feb 2001. The Station is located in an open field 200 m north of the Shaler Station, in a site chosen to minimize the angle of surrounding trees above the horizon (currently 15-25 degrees from the station at breast height). The Fisher Station records air temperature, relative humidity, dew point, precipitation (water equivalent of snow), global solar radiation, PAR radiation, net radiation, barometric pressure, scalar wind speed, vector wind speed, peak gust speed (1-second), vector wind direction, standard deviation of wind direction (wind measurements at 10 m height), and soil temperature (10 cm depth). Instruments are scanned once per second, and 15-minute (hourly before 2005) and daily values are calculated and stored by a datalogger. Data for the current month are available online, updated every 15 minutes, with out-of-range values replaced by NA but values not otherwise checked. Earlier data are checked and archived with missing, questionable, and estimated values flagged, following methods of the LTER ClimbDB project. A log of events affecting station measurements (e.g., instrument repair and recalibration, ice storms, lightning) and selected monthly and annual values are also posted.

费希尔气象站（Fisher Meteorological Station）于2001年2月11日正式投入运行。该站点坐落于谢勒站（Shaler Station）以北200米的开阔田野中，选址旨在最小化周边树木对地平线的遮挡角度，当前站址胸高位置的树木遮挡角为15~25度。费希尔站的观测记录涵盖气温、相对湿度、露点温度、降水量（积雪的水当量）、全球太阳辐射、光合有效辐射（PAR radiation）、净辐射、大气压强、标量风速、矢量风速、1秒阵风峰值风速、矢量风向、风向标准差（风速测量高度为10米）以及10厘米深度的土壤温度。仪器每秒完成一次数据扫描，数据记录仪会计算并存储15分钟（2005年前为每小时）和每日的统计值。当月数据可在线获取，每15分钟更新一次，超出合理范围的值将被替换为NA，但未进行其他质量核查。早期数据则按照长期生态研究网络（LTER）ClimbDB项目的规范开展质量核查并归档，对缺失、存疑及估算值均予以标记。此外，影响站点观测的事件日志（如仪器维修与重新校准、冰暴、雷击）以及选定的月度和年度统计值也已对外发布。如需获取当前数据，请访问：http://harvardforest.fas.harvard.edu/meteorological-hydrological-stations。如需获取完整的归档数据集，请访问：http://harvardforest.fas.harvard.edu:8080/exist/xquery/data.xq?id=hf001。
