IMD data is based on rain-gauge observations across India and interpolated to a regular grid. It is treated as a strong observational reference for long-term rainfall analysis and monsoon behavior tracking.

Approx. 100 km coarse resolution
Higher reliability over land regions
Suitable for long-term climatology
Daily average precipitation basis
Tracks monsoon trend changes clearly
Station-density limits in sparse regions

What are you seeing?
Monsoon rainfall across India shows a declining trend over the past 70 years, with increased variability in recent decades.
Why it matters
This decline is linked to changes in atmospheric circulation patterns and regional warming, which affect moisture transport from the Indian Ocean.
