In plain English

What it measures. Daily rainfall over India on a fine grid, built from the country's dense rain-gauge network — the official, ground-based record of the monsoon back to 1901.

How it's made. The India Meteorological Department interpolates thousands of rain gauges onto a 0.25-degree grid.

How & where you'd use it. The authoritative baseline for monsoon, drought and flood analysis — and the ground-truth to validate satellite rainfall (IMERG/CHIRPS). Free from IMD Pune.
