| LTspice models | LTspice is a free electrical circuit simulation program .. which I use to simulate thermodynamics with a strong emphasis on the atmosphere. |
| Insolation Calculator | This calculator computes the amount of Sun light perpendicular (normal) to the surface of the Earth for each hour of each day of the year (almost). |
| Warming Calculator | Estimate the change in temperature based on constant heating (energy imbalance) |
