Data Description:

The network selected to work out these regional means of maximum and
minimum temperatures consists of 121 uniformly distributed
stations for which temperature data are available from 1901. Adequate
care has been taken to ensure that the data are homogeneous and free
from changes in observational procedures. All-India and six regional
means of the temperatures have been worked out by computing the
arithmetic means of the data at stations comprising the region.
The regions have been delineated based on their distinct climatic and
geographical settings.
