I used this function to convert from specific humidity to relative humidity. A few of my values (about 6%) were above 100% relative humidity. The data I am using is straight from CMIP5, and has not been altered. All the variables are in the correct units. Any idea why I have impossible above 100% values?????? (there are some that are 100.2% and others that are 120%). The rest of the values look normal around 60 - 90 percent.
