Just to get more insights, we used variable"Station code" and created seven different models to make a comparison against the Global model.
Out of all the variables, the main variation that was observed was for Relative Humidity compared with Max. Temperature.

a) Histogram for Max temp:
For Station codes Chopadvav and Ukai we are observing a bimodal histogram for the data values of Max. temperature.
For other Stations, the distribution of the data was more likely to be Normal distribution.
b) Histogram for Relative humidity:
For Station code Godsamba and Kakrapar, a left-skewed distribution is observed as a large number of data values is occurring on the right side and fewer data values on the left side.
Cumulative RMSE of all the Station code models: 2.43
