Roadblocks

Daily rainfall information at a weather station level is very useful data. It can be used for analysis and planning. A district average can't help people plan or monitor a situation in a real time manner. It is possible to aggregate up for trends but deaggrating is impossible especially for places like Uttarakhand where the climate can change drastically from one area to the other.  

Rainfall maps for the period of 100 years were created to see the changing patterns and differences over time.

Data used

MET data was used to generate the maps for every year.

The Indian Meteorlogical Department (IMD) defines drought as ‘the consequence of a natural reduction in the amount of precipitation over an extended period of time, usually a season or more in length, often associated with other climatic factors (viz.

Groundwater is water that is stored underground in aquifers or rock layers than can absorb water. India gets 85% of all its drinking water from this source.   

Rainfall is an essential part of monitoring groundwater as it recharges the aquifer and brings groundwater levels up. Rainfall and well levels are important parameters for data collection.

Groundwater is water that is stored below the ground in aquifers, or rock layers that can absorb water. India gets 85% of all its drinking water from this source.
