I have downloaded IMD Gridded data (0.25 by 0.25 resolution) from the IMD website for my study I need monthly rainfall data. How to convert daily gridded data to monthly and seasonal rainfall data
Hope you are doing well. Please Eviews software has the option of data conversion, either from low frequency data to high frequency data or vice versa. You may watch videos on it from YouTube to guide you on that. Good luck
I have used this data the simple procedure is to use grads. The data comes with ctl file you can just export the data you need using the simple commands like set lat lon (Location of your area) and then you can save the file directly in excel.
You can use following commands
Open {file name}.ctl
Then select your area using command
Set lat
Set lon
Then you need to set time e.g. if you want average data for January month {January months Julian date = 1 to 31} write following command
Jan = ave (rf, t=1,t=31) t is time here and rf is the variable i.e. rainfall in this example. Then you can write this command to display your data
d= Jan
If you want the data for further statistical analysis you can directly export the data is csv format and many of the statistical work on it including excel, sigma plot, matlab, r etc. So for that you can write this command
