Ratiocalc R

Ratiocalc is a computational program suited for processing volcanic gas concentrations time series produced from any multisensor device  (aka MultiGAS analyzer).

It is primarily intended for calculating gas molar ratio (e.g. CO2 and SO2 ) and error respectively, from the slope and the correlation coefficient of the best-fit line. In addition, Ratiocalc provides an integration of satellite maps from Google® (by the Google Static Maps API) that enables the identification of the gas sources and/or topographic elements.

R is a freely available language and environment for statistical computing and graphics. It works on Windows, Linux and Mac.

A portable stand-alone version of R and Ratiocalc for Windows is available here. It can be run by executing the Ratiocalc.bat file.

For those familiar with R (https://cran.r-project.org/), the source code for Ratiocalc is available on github.
