Does personal use include using the data for publication purpose I am a researcher and am interested in a weather data. I found a suitable data at Weather Grounded Organization. I would like to use this data for my research project (publication). However, I do not know whether I can use it in my publication as it will be a personal use.  At the terms of use, I found this:

Any help, please?
Yes, you contact them and get permission.

Section 1 that you quote states:


  You may access, view and make copies of the Data in the Site for your
  personal, non-commercial use and will not publish or otherwise
  distribute the Data for any other purpose


Which means you cannot publish that data in any form, which is what you say you wish to do.

So, contact them, you might find they give you qualified permission.

Edit: Buffy's comment is important, so I have borrowed it:

you have to assume that a non response means you cannot use it. Permission is required
