Atmosculator is a freeware Mac OS X application, written using Cocoa & Objective-C, that calculates key properties of the Earth's atmosphere as a function of altitude using the 1976 Standard Atmosphere Model. It includes extensive Help on the basis of the model and a mathematical derivation showing how the properties are calculated.
What is new in this release:
- The first Intel-native release; it should run on any Mac with an Intel processor running OS X 10.7 or later.
- It has been released as a beta with a 3 month expiration (good until 2/28/15) so you can help with testing.
- If any problems are found during this period, I will include fixes in the official 3.0 release early in 2015
- A sign error in Atmosculator's built-in documentation, has been fixed. The sign used in front of the h in the numerical solutions should have been - not + for the altitudes between 167,323 and 232,940 ft and also between 232,940 and 278,386 ft. Please see this ERRATA for the online documentation. Thanks to R. Wayne Wilson for catching this.
- A typo in the formula for the gas constant in Atmosculator's built-in documentation has been fixed. Under Gas Properties, the equation for the Specific Gas Constant in terms of the Universal Gas Constant should read R = R*/M and not R = R**M. Please see this ERRATA for the online documentation. Thanks to Quentin Minster for catching this.
Mac OS X 10.2 or higher
