This type of graphics software is often used to display results from earth sciences numerical models.

They found that these compared very well to numerical models of the lens' performance.

Let us now consider a numerical model illustrating these points:

The primary approach in this case is to create numerical models to calculate the properties of interest.

A variety of methods are used to gather observational data for use in numerical models.

Therefore the measurements are generally used as the input for numerical models.

If that is the case then why did the numerical models based on those 'known' forcings get their projections so wrong?

The code for many numerical models in academic use is widely available.

"I did a numerical model just to estimate the size of the eruption," he told me in an interview.

It wasn't until the 1950s that the numerical models were getting close to being realistic.
