The updates in the file get used if you use the mcunpack script in the ~mcidas/mcidas7.6/update directory and then cd to the ~mcidas/mcidas7.6/src directory and do a make all followed by a make install.all. >Also, is there any mailing list where these are >announced? I am currently subscribed to the mcidas-x list. The addenda are not announced by email. They are "announced" on the McIDAS-X homepage, and users are encouraged to check it from time to time. re: I could not get listings of GRID files off of cirrus >I am not sure what you mean here. Our ADDE server has always been >cirrus.lsc.vsc.edu. When I "point" at cirrus, and try to get a listing of GRID files, here is what I see: DATALOC ADD RTGRIDS CIRRUS.LSC.VSC.EDU Group Name Server IP Address -------------------- ---------------------------------------- RTGRIDS CIRRUS.LSC.VSC.EDU <LOCAL-DATA> indicates that data will be accessed from the local data directory. DATALOC -- done DSINFO G RTGRIDS Dataset Names of Type: GRID in Group: RTGRIDS Name NumPos Content ------------ ------ -------------------------------------- ALL 400 Real-Time Grids ECMWF 10 ECMWF Grids ETA 40 ETA Grids JET 10 LSC Jet Stream Grids MISC 10 Miscellaneous Grids MRF 100 MRF Grids MRF-UW 2 MRF Grids in UW stream NGM 40 NGM Grids NGM-UW 2 NGM Grids in UW stream RUC 80 RUC Grids DSINFO -- done GRDLIST RTGRIDS/MRF.ALL FORM=FILE GRDLIST: No Data Found GRDLIST - done GRDLIST failed, RC=2 The fact that I can get a listing from DSINFO tells me that the ADDE remote server is installed and is operational. The "No Data Found" message from GRDLIST tells me that either there is no data (i.e., no GRID files) in the dataset RTGRIDS/MRF or that the ADDE setup is incorrect (the mapping between GRID files and ADDE data set). The ADDE setup can be checked from your end by running the following in a McIDAS-X session: DSSERVE LIST RTGRIDS This will tell us the mappings between actual GRID files and the datasets that are supposed to contain them. The output from this should look like: GRDLIST RTGRIDS/MRF.ALL FORM=FILE DATASET NAME: RTGRIDS/MRF Dataset Position Creation Date Max Grids Directory Title ---------------- ------------- --------- ------------------------------- 7 2000187 5000 ALL 00Z MRF 0 HR<=VT<=24 HR 8 2000188 5000 ALL 00Z MRF 0 HR<=VT<=24 HR 17 2000187 5000 ALL 00Z MRF 24 HR< VT<=48 HR 18 2000188 5000 ALL 00Z MRF 24 HR< VT<=48 HR 27 2000187 5000 ALL 00Z MRF 48 HR< VT<=72 HR 28 2000188 5000 ALL 00Z MRF 48 HR< VT<=72 HR 37 2000187 5000 ALL 00Z MRF 72 HR< VT<=96 HR 38 2000188 5000 ALL 00Z MRF 72 HR< VT<=96 HR 47 2000187 5000 ALL 00Z MRF > 96 HR 48 2000188 5000 ALL 00Z MRF > 96 HR GRDLIST - done When we get the remote ADDE access working to your machine, I can look through the GRID files in the RTGRIDS/MRF dataset to see if they look like what I suspect. After that, I can help you track down (through a possible reconfiguration of the XCD grid decoder setup files: RTMODELS.CFG and NOGRIB.CFG)) the reason that you do not have all of the GRIDs as Bill noted earlier.
