Garden with Insight v1.0 Help: interpolated


When you interpolate a value, you calculate it based on its position between (inter) two other values. For example, if I need a value one third of the way between six and seven, I can interpolate the value by dividing the distance between six and seven by three (7 - 6 = 1.0 / 3 = 0.33) and adding that to the smaller value (6 + 0.33 = 6.33). I have interpolated the value 6.33 as one third of the way between six and seven.

In this simulation interpolation is used to calculate values of long-term average temperature, precipitation, solar radiation, relative humidity, and wind speed for each day based on values for each month. To calculate the long-term average value for any day (say June 26th), the simulation interpolates between the value for the midpoint of the month before the date (June 15th) and for the month after it (July 15th). This produces a more realistic smoothly changing weather picture than the monthly values.

How it works:
