Upload rainfall data
Upload tabular rainfall files or NASA/Earth-observation scientific files. The temporary upload limit is 1000 MB. Uploaded files, generated results, graph data and progress files expire automatically after six hours.
Supported rainfall-data formats
NASA-style NetCDF
Use .nc or .nc4 files containing dimensions, coordinates, variables, units and time metadata.
NASA CDF
Use .cdf for NASA Common Data Format files. CDF is inspected separately from NetCDF.

Scientific calculation rules
Rainfall aggregation
Depth: sum valid interval depths.
Intensity: convert to depth, sum, then divide by target duration.
Rainfall disaggregation
Preserve the original total using equal shares or normalized user weights.
Every finer value is labelled estimated.
Acceptance checks
Verify timestamp order, duplicates, missing periods, negative values and rainfall mass balance.
