1. Create a new column. In this example, I call it "total".

2. Put the following formula in the new column:

(ignore this line)

The formula takes the value of tair in the current row, and adds it to the previous value of total, thus creating a cumulative sum.

If you only want to accumulate the values if they are greater than or equal to 5, then use the formula:

(ignore this line)

The formula looks at the current value of tair, and if it is less than 5, instead of adding tair, it adds 0.
