------------------------------------------------------------------------------------------------------------------- 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) Currently, Harmonic constants from COOPS (in "fix" directory) are used for tide prediction IMODEL and JMODEL might be used to extract Harmonic constants from tidal forcing file of ROMS for purpose of detide. 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 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)
