Data Gaps: all data streams
- June 20, 2007 to October 28, 2007: Lost data/failure to log data.
- November 25, 2009 to December 2, 2010: Weather station repaired after electrical storm.
- July 13, 2012 to July 27, 2012: Weather station repaired after electrical storm.
Data Gaps: Total Radiation
There are several gaps in the Total Radiometer data stream, due to instrument maintenance issues. These gaps are all filled with "nd":
- 2006 to August, 24 2009 23:59 software issue (calculation error)
- May 21, 2014 14:45 to May 22, 2014 9:45
- December 29, 2015 5:45 to January 3, 2016 12:15
- October 6, 2016 onward due to maintenance difficulties, the Total Radiometer was removed permanently.
Data calibration: Solar Radiation_PAR
The Solar Radiation_PAR meter drifted out of calibration from 2013 to 2021, evidenced by a steady decline in slope when the data were plotted against Solar Radiation_Energy. Rad_PAR were adjusted in these years using an annual correction factor that restored the expected linear relationship between Rad_PAR and Rad_Energy (2.112, the mean of slopes from 2006-2012). The correction factor for each year is a follows: 2013: 1.189, 2014: 1.235, 2015: 1.252, 2016: 1.254, 2017: 1.320, 2018: 1.336, 2019: 1.406, 2020: 1.366, 2021: 1.364.
Data availability:
These data are live streamed to the FHL website: http://wx.fhl.washington.edu/vdv/VV_Frame.php
These data are also archived in near real-time at NANOOS (http://nvs.nanoos.org/Explorer) as asset FHL_friharbor1.
The data available here at BCO-DMO differ from the above in that they are presented in yearly blocks and have been fully verified.
