General Data disclaimerThe mooring web pages are currently under contstruction, and no guarantee is made about the validity or accuracy of these data. The pages are intended for the use of ICON investigatiors only at this time.
If all the values for an instrument are -99's then that instrument is either absent or not returning any good data.
General Mooring Quality ControlTemperature, salinity, humidity, air pressure, and wind speed data are flagged using 2.25 biweighted standard deviations from the biweight mean. The method is based upon that outlined by John R. Lanzante in International Journal of Climatology Vol 16 pp. 1197-1226 (1996).
Bad and Flagged Met or CTD dataNull or Bad values are listed as -99. On the plots, data within the bounds of the plot but marked bad are plotted in red. Data outside of the plot's bounds are plotted as red triangles in the upper part of the graph.
Bad or Flagged MicroCat DataNull or bad values of microcat data are listed as -99. Data which is flagged as bad that plots within the bounds of the plot are plotted as black circles with the central dot the color of the depth of the bad data. Bad data which lies outside of the bounds of the plot are plotted as circles in the color of that depth at the top or bottom of the plot.
Bad or Flagged ADCP DataNull or bad values of ADCP data are listed either as -99 or -3278.2. If the whole profile consists of -99's, the instrument is either absent or failing to send valid data. Values marked with a -99 or -3278.2 are marked bad internally by the RDI software. Additionally, data is flagged as being bad, but the values are not changed. The data is flagged as being bad if any beam has a correlation value below 64 or if the percentage good for both 3 and 4 beam solutions are less than 25 percent. On the plots, data within bounds but marked as bad are plotted in black. Data out of the plot's bounds are plotted as blue triangles.
Data Quality Control Bounds
Data are flagged using a biweighted standard deviation. If a datum falls more than 2.25 (2 for M3 air temperature) standard deviations away from the biweighted mean, it is flagged as bad. The method is based upon an article by John R. Lanzante in International Journal of Climatology Vol 16 pp 1197-1226 (1996).
Mooring CTD ComparisonDifferences were computed between the R/V Pt. Lobos CTD and the MicroCat CTD sensors on the moorings.
