GLOSSARY: NSTA : Total number of observation/climatology stations NOBC : Total number of ocean model open boundary grid points DELT : Time interval to final open boundary condition time series SECTION 1: NWLON TIDE GUAGE INFORMATION SID : sequential number of observational station NWLON_ID : NWLON/PORTS tide gauge ID(NWLON, BUOY, CMAN, USGS,etc.) NWS_ID : NWS SHEF ID which is used to extract real time data from NWS BUFR files DATUM : Datum to convert water level from MLLW to MSL FLAG : indicator of it is a primary or backup station, =0, used as a primary station for WL OBC correction using real time observations =1, used as a backup station for WL OBC correction using real time observations TS_FLAG : indicator of whether it is used for T/S boundary condition, =0, no T/S data are used; =1, real time T/S obs are used to specify T/S open boundary conditions; climatology is automatically used if no real time is available; =2, use static historical data set to specify T/S open boundary conditions. if TS_FLAG > 0, T/S climatology have to be specified. BACKUP_SID: SID of backup station for this station. The real time obs at BACKUP_SID is used to this station. If BACKUP_SID <=0, there is no backup for this station. For instance for DBOFS, Atlantic City's backup station is Cape May (BACKUP_SID=4) GRIDID_STA : GRIDID of open boundary grid point in Section 2 which the observation gauge corresponds to. From GRIDID_STA, IROMS and JROMS can be found in Section 2 GRIDID_STA <= 0 means the station is out of model domain. For a primary station, GRIDID_STA must be a GRIDID listed in Section 2. For a backup station, GRIDID_STA can be same as its primary station, and may not be used. Then the difference between obs and ETSS is computed as, diff (error) = Observed SWL (SID) - ETSS(GRIDID_STA) AS : correlation coefficient between primary and backup stations, or scaling factor to project SWL from backup station to primary station. ----------------------------------------------------------------------- SECTION 2: CONFIGURATION OF LATERAL OPEN BOUNDARY GRIDID : sequential number of open boundary grid IROMS : grid index along XI direction of ROMS JROMS : grid index along ETA direction of ROMS WL_STA : Number of observed stations used for correction of water level OBC, =0, no correction by observations, use data source of DBASE_WL =1, correct OBC generated from data source DBASE_WL by observations from one guage station,therefore,the correction at this grid is, correction=obs_1 * WL_S_1 =2, correct OBC generated from data source DBASE_WL by observations from two guage stations,therefore,the correction at this grid is, correction=obs_1 * WL_S_1 + obs_2 * WL_S_2 WL_SID_1 : SID (first column in Section 1) of first gauge station WL_SID_2 : SID (first column in Section 1) of second gauge station, it is dummy if WL_STA=1 WL_S_1 : scale factor to multiple observation at first gauge WL_S_2 : scale factor to multiple observation at second gauge TS_STA : Number of observed stations used for correction of T & S OBC, =0, use data source of DBASE_TS, no correction by observations =1, use data source of DBASE_TS, but corrected by observations from one guage station,therefore,the correction at this grid is, correction=obs_1 * T_S_1 =2, use data source of DBASE_TS, but corrected by observations from two guage stations,therefore,the correction at this grid is, correction=obs_1 * T_S_1 + obs_2 * T_S_2 TS_SID_1 : SID (first column in Section 1) of first gauge station TS_SID_2 : SID (first column in Section 1) of second gauge station TS_S_1 : scale factor to multiple observation at first gauge TS_S_2 : scale factor to multiple observation at second gauge OBC_ID : indicate which side of OB: "S" for southern open boundary; "N" for northern open boundary; "W" for western open boundary; "E" for eastern open boundary. ----------------------------------------------------------------------- NOTES 1. For interpolation, all open points are treated in same way no mater whichever boundary the point is on. Then using OBC_ID to assign to corresponding boundary variables (e.g. zeta_south, temp_south, and so on) 2. Then the difference between observation and ETSS is computed as, diff (error) = Observed SWL (SID) - ETSS(GRIDID_STA)
