How to fit multiple normal distributions to another distribution in order to describe it?

I am currently working on a project where there is one heated plate and i take temperature measurements over it with the help of 3 different thermocouples (which have the same distance from the plate surface) at different heights. Each thermocouple at each height has n=320000 data points (temperature measurements), that can be displayed graphically as a probability distribution which reminds a normal one. I would like to know if there is a way to fit multiple univariate normal distributions on the one produced by the data that could describe it as well as possible.Thanks in advance.
P.S. I have attached a file that shows the produced distribution (which looks a lot like a normal one) of the third thermocouple at height z=2mm

Yes, that does look a lot like a normal distribution. It seems that it would be pretty well desribed by its mean and standard deviation, which you could compute from the data that went into the distribution.
Could you explain more about what you are trying to do? What do you mean by "fit multiple univariate normal distributions"?
