The Fisher Meteorological Station became operational on 11 Feb 2001. The station is located in an open field 200 m north of the Shaler Met 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 Met Station records air temperature, relative humidity, dew point, precipitation (including 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 monthly 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.
For current data, please see: https://harvardforest.fas.harvard.edu/met-hydro-stations. For a longer climate record that includes adjusted data from the Shaler Met Station, please see dataset HF300.

Observation periods
15-minute: 15 minutes, ending with given time. Hourly: 1 hour, ending with given time. Daily: 1 day, midnight to midnight. All times are Eastern Standard Time.
Instruments
Air temperature and relative humidity: Vaisala HMP45C (2.2m above ground). Precipitation: Met One 385 heated rain gage (top of gage 1.6m above ground). Global solar radiation: Licor LI200X pyranometer (2.7m above ground). PAR radiation: Licor LI190SB quantum sensor (2.7m above ground). Net radiation: Kipp and Zonen NR-LITE net radiometer (5.0m above ground). Barometric pressure: Vaisala CS105 barometer. Wind speed and direction: R.M. Young 05103 wind monitor (10m above ground). Soil temperature: Campbell 107 temperature probe (10cm below ground). Data logger: Campbell Scientific CR10X.
Instrument and flag notes
Air temperature. Daily air temperature is estimated from nearby stations as needed to complete the record.
Precipitation. Daily precipitation is estimated from nearby stations as needed to complete the record. Delayed melting of snow and ice (caused by problems with the rain gage heater or heavy precipitation) is noted in the log--daily values are corrected if necessary but 15-minute values are not. The gage may underestimate actual precipitation under windy or cold conditions.
Radiation. Snow and ice may be removed from radiation instruments after precipitation events. Depth of snow or ice on instruments and time of removal are noted in the log, but values are not corrected or flagged.
Wind speed and direction. During ice storms, values are flagged as questionable when there is evidence (from direct observation or the 15-minute record) that ice accumulation may have affected the instrument's operation.
