<div>Is there a way to use the tmave function in order to make a composite of data which for example, SST is greater than 25 and SLP is less than a certain value. In other words, filter data based on the criteria of two separate variables? I am trying to find the average wind speed over a period of a year for days when the SST (sea surface temperature in a certain area is greater than 25, while the average SLP (sea level pressure) in a particular region is less than 900 mb. Do I have to use a LOGIC function such as AND here? Anyway, let me know how to approach this with the tmave/maskout functions.<br>
<br>Thanks,<br> <br>jason</div>
