Key to table below ------------------ NumObs : number of observations from the ship during the month %GE : percentage of obs with gross errors (for GE limits see below) StdDvn : standard deviation of obs-background, excluding obs with gross errors Bias : mean obs-background, excluding obs with gross errors RMS : root mean square of obs-background, excluding obs with gross errors Suspect selection criteria for each variable: At least 20 observations from the ship and one or more of the following:- %GE > 10% |Bias| > Bias limit (see below) StdDvn > StdDvn limit (see below) Limits: | Press.| Wind Speed | Direct.| Air Temp.| Rel.Hum.| SST | ------- | (hPa) | (m/s) | (deg) | (deg C) | (%) | (deg C)| Bias limit | 2.5 | 5 | 30 | 2.0 | 12 | 2.0 | StdDvn limit | 5.0 | 10 | 60 | 4.0 | 20 | 4.0 | GE limit | 15.0 | 25 | 150 | 10.0 | 50 | 10.0 | Callsign Element NumObs %GE StdDvn Bias RMS ------------------------------------------------------------ MZER8 P* 23 0 2.3 2.8 3.7 A8IP5 RH 37 0 8.5 17.7 19.6 C6KD6 RH 27 0 9.6 15.3 18.1 DCPY2 RH 36 0 20.6 -0.4 20.6 MZER8 RH 23 0 12.7 -16.7 21.0 PDHO RH 46 0 8.3 -12.8 15.3 VCRG RH 43 0 6.0 26.5 27.2 DDVK2 SPEED 39 10 3.8 5.4 6.6 DDVK2 DIRN. 22 18 88.1 55.6 104.2 C6RI4 SST 36 0 1.0 2.4 2.6 CGBY SST 28 0 0.7 2.8 2.9 CGDP SST 240 100 PBEN SST 43 0 0.6 2.2 2.3 WFLG SST 51 0 0.6 -2.4 2.5
