 Software

 

  • Rainfall Analysis and INterpolation (RAIN) – Designed and Developed by Dr. Ramesh Teegavarapu (2012). Available in Public Domain.

RAIN provides several spatial interpolation methods for estimation of missing precipitation data at a site. Analysis of rainfall in space and time is also possible using RAIN. This software can also be used for interpolation of hydrometeorological variables. RAIN software provides over 20 deterministic and stochastic interpolation methods.
