From these forms, you will have access to monthly statistical information of the data provided by databuoys and Voluntary Observing Ships sending messages on the GTS. You can access the statistical indicators through several options :
  1. By unique Identifier, which will show you either last 2 years of data if you choose the "Table" option, or the graphic representation corresponding to some of these statistical indicators if "Graphs" is chosen for display,

  2. By country, where you will have acces for a given month to all the buoys or ships for that country

    3.   Please note that the country and station informations are based on updated metadata files from OceanOPS.
If values of indicators exceed warning thresholds, they appear in red in the tables.
In the graphs, the red lines indicate the threshold value for the displayed statistical indicator if defined. Below are displayed the thresholds values used:

Parameters Bias Standard Deviation RMS Gross Errors
Pressure |Bias|> 1.2 hPa SD > 1.5 hPa / |Obs-Model|≥ 10 hPa
Temperature |Bias|> 3 °C / RMS > 6 °C |Obs-Model|≥ 15 °C
Humidity |Bias|> 7 % SD > 10 % RMS > 10 % |Obs-Model|≥ 40 % (*)
Wind Speed |Bias|> 4 m/s / / |Obs-Model|≥ 15 m/s
Wind Direction |Bias|> 25 deg SD > 60 deg / |Obs-Model|≥ 100 deg
SST |Bias|> 3 °C SD > 3 °C RMS > 1.5 °C |Obs-Model|≥ 5 °C

The value for the number of Gross Errors (GE) threshold is 5.

(*) : Before September 2021, the threshold for Humidity Gross errors was 15 %
