Problem reading GEOS-4 TROPP files

Dave MacKenzie wrote:

We encountered an I/O Error 29 with file 69 when trying to run GEOS4 v8-01-01 with the variable tropopause turned on at 4x5 resolution. When I investigated this problem further, I found that there was no code written to copy and unzip the YYYYMMDD.tropp.4x5.gz files. Since I didn't see any mention of this online for v8-01-01 or newer versions, I thought I should bring it to your attention.

The *.tropp* files are accessed in i6_read_mod.f but there is only code included to use the data in those files and erase them from the TEMP directory. No code was included to actually copy them into the TEMP directory and unzip them. I wrote in a few lines of code and our problems disappeared. After running the code for one day, it finished smoothly with no problems. Then I tried running it for 2 years and it crashed after two months (I/O error 67 in file 72, input statement requires too much data). I don't know if it's a related problem to the changes I made or something else, but I thought I'd bring this to your attention. Thanks!

Yes...the TROPP files for GEOS-4 were an afterthought. We have always stored the GEOS-4 data as uncompressed, in order to avoid the problem. That might be a good solution if you have the disk space.
