Calculations of atmospheric and molecular absorption spectra of gases using the HITRAN database. The user specifies the concentrations of molecules, total pressure, temperature, optical pathlength and other parameters which are used to model the gas mixture optical transmission spectra as a function of wavelength. Automatic HITRAN database downloads (from HITRAN.org) or manual placement of the database onto the portable device. Temperature, total pressure, wavelengths and molecular concentrations may be specified. An external SensorTag Bluetooth module (ti.com/sensortag) may be connected to obtain empirical values of total pressure, temperature and humidity as input for line-by-line calculations instead of manual entry (the built in cell phone sensors are not currently supported under the Universal Windows Platform). Voigt, Lorentzian and Doppler lineshapes. Instrument functions. Built in atmospheric models. Sharing calculation results (images and data) from within the application. Absorption, Transmission or Optical Depth spectra. Currently limited to horizontal path mode. Additional information is available in the following publication, http://dx.doi.org/10.1007/s12145-017-0288-4 (a view only version of this publication is available at http://rdcu.be/piDB).
What's new in this version
Support of SensorTag (ti.com/sensortag) - a keychain size coin battery operated Bluetooth device containing temperature, pressure and humidity sensors to model spectra based on measured meteorological parameters.
