VOS-Clim ship suspect list for February 2013
   *************************************************
	   
 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  |
