Software

 

  • Rainfall Analysis and INterpolation (RAIN) – Designed and Developed by Dr. Ramesh Teegavarapu (2012). Available with Book purchase.

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.

BAT is developed to evaluate radar data using several statistical and performance indices. It is can used for evaluation of hydrologic models and any simulation model-generated results. BAT can be used for forecast verification of precipitation forecasts available from National Weather Service (NWS). Currently used by SFWMD. BAT consists of several error and performance metrics for evaluation of radar data at different temporal and spatial resolutions.
