Hello Mina,

Thanks for sending the complete output of the tool. From what I see there, I believe there are two main possibilities for this problem:

1. There was a problem specifically with that one file, which was the MUR SST for 25 January 2007. I just tried building a climatology just using data from 2007 and it worked, so I don’t think this is the issue.

2. There was a problem connecting to the NASA server or the server itself stopped responding. It could have been a problem with your internet connection, or the NASA server could have been temporarily offline for maintenance.

The tool is designed to retry the download, but by default it only does so for 300 seconds. You can adjust this in the tool under OPeNDAP Options --> Maximum retry time. In my experience, it is rare for the NASA server to be down at all, and if so it is usually only for a few minutes. Perhaps if you adjusted the timeout to 7200 seconds (two hours) then it would handle most temporary problems.

Building a climatology from MUR SST can take a long time, because of the large amount of data. If your process is interrupted, like you happened to you, then you have to restart from the beginning. This can be frustrating. You can speed up the tool on restarts by telling it to use a Cache Directory. You should create a directory specifically for this purpose; do not use it for anything else (don’t store your documents in it). The tool will store the downloaded data there as it proceeds. If you have to restart the tool, it will use data from there rather than redownloading it. Whatever is not in the cache, it will download.

If you do that, I recommend keeping your eye on the size of that directory so it doesn’t fill up your disk. You can always delete it. There is no harm in doing that.

Best,

Jason
