Hello Jessica,
You can use the Formula tool to transform any signal to continuous (tolinear()), discrete (todiscrete()) and step (tostep()). You also need to be careful about the max interpolation period between samples. You can add that parameter as an argument in the formula. For example: $temp.tolinear(24h).
Can you please test these formulas and let me know if this works.
Have a good day,
Selmane
