RadioSonde is a contributed package to the R Project for Statistical Computing and provides a means of reading a radiosonde profile and creating the standard SKEW-T, log p graphic.

RadioSonde is a set of R functions that ingests common radiosonde datafiles into R and can create SKEW-T, log p diagrams and wind profile plots. Radiosondes are a very common instrument in the atmospheric sciences. Several thousand radiosondes are launched every day by the World Meteorological Organization and they provide data used by all the operational weather centers.

The SKEW-T, log p plot is the most common diagram to examine radiosonde data and shows the relationship of the current state of the atmosphere against families of curves that represent certain theoretical relationships.
