Author Topic: Dew Point and Relative Humidity tables have errors

We have several ways to find dew point in the Weather Trainer, but they ultimately all lead back to two tables: G195 which uses Celsius degrees and an automated interface that interpolates that table, and G196 which uses Fahrenheit degrees.

The Celsius table and the interpolator give wrong results in at least some cases, because the table is wrong. We will fix this as soon as possible and then make an announcement here.

The Fahrenheit table is correct for dew point, b ut it is wrong for some Relative Humidity values. Some how these have been mixed up.

In the meantime, a very convenient way to find dew point is in the automatic calculators that we have packaged under the name NIMA Navigation calculators—this also has weather computations in it. You can download this at no charge from the Freeware section of our downloads page.
