The answer to this question is made a bit more difficult because the question does not state what the paper's thesis is. The thesis statement is presumably making some kind of argumentative statement about meteorological instruments and geography. The body of the paper will then be providing evidence as to why that thesis statement should be believed. The conclusion's job is then essentially two things. The first is to remind readers of what the thesis statement was and to provide a quick overview of the supporting evidence. This is the hardest part of the conclusion because you have to find a way of doing this without sounding overly repetitive. The thesis reminder should not be a copy and paste of the introductory paragraph's thesis. The second thing that the conclusion should do is steer your readers toward caring about your topic or even pushing them to do something about it. This is also tricky, because in an academic paper, it should not be an emotional appeal. The reader needs to be logically led to thinking that the paper's thesis is worth caring about. Finally, the one thing that the conclusion absolutely must not do is introduce new lines of thought. Do not include a new thesis statement or evidence that supports the original thesis that was not discussed in the body of the paper. This is a common mistake for many writers. If it is important enough to go in the conclusion, then it needs to have been in the body.

A good conclusion should wrap up your meteorological instruments project and give you one last chance to support your ideas on the topic. A conclusion allows you to make new connections and relate the findings of your project to a broader issue or new area of thought. 

Your conclusion may answer one or more of the following questions:

• Why was my project important?
• What knowledge or ideas do I want the reader to take away from my project?
• What points do I need to fit together and synthesize?
• Is there an action I want my reader to take after learning about my project?
• Are there broader implications that need to be considered?

When writing a conclusion, you should avoid stating your thesis for the first time or introducing new evidence. The conclusion is a wrap-up of your project and should not include new information, just expand on the information already introduced. You should also avoid restating your thesis statement without expanding on your ideas. Finally, emotional pleas or personal information about the topic do not belong in an academic paper.

Without seeing your actual project, I cannot provide a specific conclusion for your topic, but I hope the above tips will help you come up with an outstanding conclusion based on your work.
