VOS-Clim ship suspect list for July 2010 ************************************************* Monitoring centre: Met Office, UK. 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 ------------------------------------------------------------ A8JR6 P* 43 0 1.5 3.4 3.8 A8CP5 T 24 0 1.7 2.7 3.2 CGBN T 632 0 3.1 3.3 4.5 WTEB T 40 0 1.5 2.2 2.7 PHHD RH 25 0 18.4 -17.5 25.4 ZCDN9 RH 20 0 16.6 -15.2 22.6 C6KD8 SPEED 48 4 3.0 6.4 7.1 C6KD8 DIRN. 32 6 83.6 -12.8 84.6 A8IP5 SST 35 0 4.0 -0.8 4.1 BATEU01 SST 310 54 2.3 3.4 4.1 C6KD5 SST 47 0 2.4 -2.0 3.1 DGWF2 SST 36 0 0.9 -2.2 2.4 DPCK SST 43 0 1.2 -2.2 2.5 FVNM SST 321 100 MMHE5 SST 24 0 1.1 2.2 2.5 PHAC SST 30 0 1.1 2.7 2.9 WFLG SST 44 0 0.8 -2.6 2.8
