All VOS-Clim ship data is monitored: against background 6-hour forecast fields for all variables except SST, for which analysed fields from the previous day are used. 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 ------------------------------------------------------------ A8KW3 P* 31 0 3.3 4.3 5.4 OWFD2 P* 69 0 2.1 3.5 4.1 WCX7445 P* 304 72 0.8 0.3 0.9 WCX7445 T 304 0 4.2 7.9 9.0 ZQDI9 T 24 0 1.8 2.2 2.8 C6SI6 RH 75 0 11.0 21.5 24.1 MSTM6 RH 24 0 24.5 7.9 25.7 ZCDN9 RH 40 0 12.2 -16.3 20.4 CGTF SPEED 127 0 3.0 -5.9 6.6 9KWP DIRN. 24 0 75.5 46.2 88.5 C6KD8 DIRN. 40 5 87.2 19.1 89.3 PCAW DIRN. 36 3 70.1 -23.5 73.9 TBWUK14 DIRN. 26 4 93.3 -26.8 97.1 TBWUK37 DIRN. 28 0 63.5 -1.9 63.5 WBP3210 DIRN. 279 0 61.0 9.2 61.7 WCX7445 DIRN. 251 0 98.0 -11.2 98.6 3ELR6 SST 29 0 1.2 2.3 2.6 9KKS SST 56 2 1.0 2.4 2.6 A8IP5 SST 58 0 1.8 2.3 2.9 A8KW3 SST 31 0 1.2 3.2 3.4 C6JE2 SST 21 0 1.9 -2.8 3.4 CGDR SST 162 4 2.1 5.1 5.5 MSTM6 SST 48 0 4.1 0.4 4.1 MYSU5 SST 50 0 2.4 2.0 3.1 VQKZ6 SST 50 0 1.9 -2.3 3.0 WCX7445 SST 658 0 3.4 5.8 6.7 WFLG SST 78 0 0.6 -2.6 2.7 WNGW SST 52 0 2.2 -2.0 3.0
