1. Tool Analyzing weather can climate data to meet user needs IRI, Columbia University

2. Prototype Tool to Map and Analyze Historical Weather Data with User-Defined Parameters Choose parameter, quantity (i.e., number of dry spells of 7 or more days), and statistic of interest (i.e. probability of exceedance)

3. User chooses parameters/statistics of interest Parameter: average daily rainfall over chosen season number of wet days mean rainfall intensity on wet days number of dry spells Statistics: Mean Standard deviation Probability of exceeding X dry spells (definition of dry spell determined by user)

4. Additional data analysis using this tool Click on a point in map to obtain a timeseries of data for that point

5. Potential for Developing this Prototype So far, 1-degree daily ranfall data from IMD is used here in password-protected area of IRI Data Library Potential for developing this tool: Host the tool here in India Use higher-resolution data to improve performance Refine the set of parameters that can be chosen
