Pretty easy, overall.
I would recommend this course, specifically ATM 101 rather than ATM 100 because it is another credit for essentially the same amount of work. The only thing different about ATM 101 and ATM 100 is the lab section. The lab section has quizzes, prelabs and labs, but they can all be done with minimal effort and in a minimal amount of time.
It was pretty straight forward, pretty easy with doable exams. The labs are very easy for 101 and often time I finish them in class. Martin is a very interesting professor and does a lot to provide an engaging lecture for students. I always come to class entertained and the material isn't that difficult to follow. You will learn a lot about weather and think about it differently from that point on.

Advice for students:
Although you don't need to attend the lecture, it is entertaining. Lots of the information covered is in the book as the book is written by the professor. He also provides an outline of the readings that need to be done by a certain time (with specific chapters).
