DialMaker

DIALMAKER is a free sundial design program. It lets you graphically design your sundial given a number of parameters, including the latitude of the site, the type of sundial (horizontal or vertical), the orientation of the receiving surface (for a vertical dial, equator-facing or not), and whether the sundial has to work in solar or in standard time. Visit the DialMaker page for more details and download.

Psychrometrics

Psychrometrics are the determination of physical and thermodynamic properties of moist air. These properties include, for example, the air's dew point temperature, its wet bulb temperature, relative humidity, humidity ratio, enthalpy, etc. Numerical Logics makes available a free library of psychrometric functions in C, and a free psychrometric calculator. Visit the Psychrometrics page for more details and download.

Distance calculator

The distance calculator is a small program to calculate the distance between two points on the surface of the earth, given their latitudes and longitudes. Visit the DistanceCalc page for more details and download.

Time Series Viewer

The Time Series Viewer is an Excel workbook used to plot large time series. It facilitates the navigation through the data and makes it easy to focus on specific periods of time through an intuitive zoom in/zoom out feature. Visit the Time Series Viewer page for more details and download.
