Problems downloading data from repository

[inos@bas_ac_uk]

Hi all,I've been having problems downloading input data files from the repository. For some reason I am not finding files that I know exist. For instance, I would like to download the solar_parms_file "wasolar_1947-2014_daily_c140408.nc", as I'm interested in an interval in Oct/Nov 2013, and the current file I have only covers dates up to Aug 2013. I know of the existence of the 2014 file I need because it is mentioned in another post on the forum, but when the model tries to download it automatically, or when I try to do it with the check_input_data script, I get the following error:svn: warning: W160013: URL 'https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/atm/waccm/solar/wasolar_1947-2014_daily_c140408.nc' non-existent in revision 15981
svn: E200009: Could not list all targets because some targets don't exist
File was not found in svn repo: https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/atm/waccm/solar/wasolar_1947-2014_daily_c140408.ncWhen I do "svn list https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/atm/waccm/solar/" I don't see the file I want either, so that is consistent with the above errors. I've had similar problems with downloading MERRA data for a specified dynamics run. Does anybody have an idea why I am not finding files that do exist on the repository?Thanks,Ingrid

I have again a problem with an input data file. The model is trying to read the file "sulfate_f_1975-2010_2deg_refc1sd_wa4_tsmlt.001_c130703.nc" in my inputdata/atm/waccm/sulf/ directory, but I only have what seems like a similar file: sulfate_f_1975-2010_2deg_refc1sd_wa4_tsmlt.001_c130702.nc. Both files mention a date range that doesn't match with the interval I'm trying to simulate (Oct-Nov 2013), although I'm not sure how important that is. When I run the check_input_data script, nothing happens. It does not throw an error about not finding a file it needs, although I've noticed that the file the model is trying to read is not available from the repository (or at least, it's not listed when I do an "svn list" on the relevant directory). Any suggestions as to what I should do?Thanks,Ingrid

Usually, the reason you run into this kind of problem is the following.From the title, I see that your file is for 1975-2010: sulfate_f_1975-2010_2deg_refc1sd_wa4_tsmlt.001_c130702.nc.If you try to run after 2010, the model will not find data in your file and it is going to look if there is another file that have more years. The way it does this it is that it increment the filename by 1: In your case, *c130702.nc -> *c130703.nc To make a long story short: There was historical naming convention why the model is doing this but this is not relevant in your case to increment the filename by 1. Indeed, in most of the cases, this not relevant to do this. This feature should be remove from CAM at some point. In summary: I believe the the reason it crashes is that you are trying to simulate a period for which you don't have sulfate data.

Ok, thanks, that makes sense. I understand now where the problem with the sulfate data file is coming from. Do you know if there are any sulfate input files available that I could use instead to simulate the 2013 Oct-Nov interval that I am interested in? Is there a recommended one to use?

I am not aware of any file based on observation but you could use files form an RCP scenario. I expect that for sulfate, it would be "good" enough
