The algorithms used in this calculator are three separate linear least squares fit of standard data:
| Present Ozone Transport Range | Linear Least Squares algorithm |
| 0.00 - 0.05 | Future transport = 1.0 * present transport |
| 0.05 - 0.16 | Future transport = 0.60822 * present transport + 0.01893 |
| 0.16 - 0.20 | Future transport = 1.0 * present transport |
