Hi Ben: The "Grid variables" are viewable in the IDV. To my eye those look like all the useful ones.You should add the "CF-1.0" Convention attribute if you plan to use CF.
Don will have to comment on the mmr unit. Ben Foster wrote:
Don: Were you able to read the files in http://download.hao.ucar.edu/pub/foster/murray with IDV? The cdmValidate that John mentioned in CF mail thismorning had this to say: No CoordSysBuilder found - using default (GDV). No 'Convention' global attribute. Coordinate Axis LBC does not have an assigned AxisTypeI was surprised that it said "mmr" are valid udunits, but I seem to recall that mmr in udunits is something different than "mass mixing ratio", which is our unit. I hope that doesnt confuse IDV. As I saidbefore, I don't like using "fraction" or "1" as units, and I don't really care if IDV can't do unit conversions on all our fields. But I wouldlike to install IDV at hao, and use it to view these model history files if at all possible... --BenFrom foster@xxxxxxxxxxxxxxxxxx Wed Jan 18 16:21:21 2006Received: from vishnu (vishnu [128.117.16.89]) by jabba.hao.ucar.edu (8.11.7p1+Sun/8.11.6) with SMTP id k0INLKU06066; Wed, 18 Jan 2006 16:21:20 -0700 (MST) Message-Id: <200601182321.k0INLKU06066@xxxxxxxxxxxxxxxxxx> Date: Wed, 18 Jan 2006 16:21:20 -0700 (MST) From: Ben Foster <foster@xxxxxxxxxxxx> Reply-To: Ben Foster <foster@xxxxxxxxxxxx> Subject: TIEGCM history files To: dmurray@xxxxxxxx, caron@xxxxxxxx Cc: foster@xxxxxxxxxxxxxxxxxx MIME-Version: 1.0 Content-Type: TEXT/plain; charset=us-ascii Content-MD5: 2cHBNznzF83h/6LCsuYHQg= X-Mailer: dtmail 1.3.0 @(#)CDE Version 1.4.2 SunOS 5.8 sun4u sparc Content-Length: 1602 Status: RO X-Status: $$$$ X-UID: 0000000001 Hi Don and John: As a follow-up to our meeting re TIEGCM netcdf history files last September (can't believe its been that long), please take a look in: http://download.hao.ucar.edu/pub/foster/murray The *p001.nc file is a "primary" history, usually used to restart the model. The *s001.nc file is a "secondary" history, with selected fields for diagnostics. There are also ncdumps of each file, with coord arrays, etc. The vertical coordinate arrays lev and ilev are the unitless "atmosphere_log_pressure_coordinate", as we discussed. If these look ok, we will propose them to the CF standard. Could you please try to read these files with IDV, especially the secondary file -- it has hourly data for a day. I know all the units are not ldunits compliant, e.g., the density fields have "mmr" units -- I feel that mmr (mass mixing ratio) is more descriptive than "1" or "fraction". I assume this means that IDV would not be able to do unit conversion on these fields, but I don't care -- if I need to look at those fields in different units, I can use our own processors -- but it would be really nice if we could begin using IDV, since it does so much that our processors cannot do...once its working, we would like to install it at hao.
