Excellent. Glad to hear it. >I ran into a problem while testing on RTGRIDS/MRF data. >All the grids saved on Cirrus are Mercator projections, and >we don't have the full set; on your server there are many >more grids and they are all Polar Stereographic. So, either >you or us, probably us, are decoding the data stream >incorrectly. What do you suppose we need to change? I am willing to bet that your XCD grid decoding is not up to the latest addendum. At some point in the not so recent past, an addendum was made to McIDAS-XCD 7.6x that covered splitting up decoding of MRF grids into MRFs and AVNs. Assuming that you are still running your ADDE server on cirrus, I see that this change has not been made: 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 Compare this to the same DSINFO listing from adde.unidata.ucar.edu; DSINFO G RTGRIDS Dataset Names of Type: GRID in Group: RTGRIDS Name NumPos Content ------------ ------ -------------------------------------- ALL 1000 All XCD Real-Time Grids AVN 100 Real-Time AVN Grids ECMWF 10 Real-Time ECMWF Grids ETA 120 Real-Time ETA Grids GRIDS 9999 All Possible GRID files MDR 10 Manually Digitized Radar MISC 10 Real-Time Miscellaneous Grids MRF 100 Real-Time MRF Grids MRF-UW 2 MRF Grids in UW stream NGM 40 Real-Time NGM Grids NGM-UW 2 NGM Grids in UW stream RUC 80 RUC (MAPS) Grids DSINFO -- done I could not get listings of GRID files off of cirrus, so I am suspicious that the ADDE server for this data, at least, has changed at Lyndon. If you could point me to the correct server machine, I could take a closer look.

Mark is checking out the latest addendii and should respond to you further. I will look in next week and see what is happening. I could probably test my scripts on the correct data stream by pointing at your server. They used to work, but the world keeps changing. I think I have almost all commands upgraded. There are still a few IGG MAKE 's, and IGU DEL then IGU MAK. I don't see that these are being sunset soon. Should I leave them or change them too? Bill
