I have a table that has four columns (longitude, latitude, date, and observed_value). In my table latitude and longitude values represent 95 unique locations that are scattered randomly. Each one for 360 months; I mean I have 360 observed_value data for each unique location from like 1/1/1989, 2/1/1989, 3/1989, ... 12/1/2018. I want to convert this scattered data to gridded data by interpolation. I want to have data for longitude = 44.25:.5:63.75 and latitude: 24.25:.5:39.75 for each month. So, in the end, I will have so many locations rather than 95 (for example 11000) that have observed_data for these 360 months.
I have been thought about it for 2 days I really search for everything but I don't know how can I do this. I want to ask you please help me with the issue. If it is important, after that I want to make 1 x n cell which each array in it is a table for these gridded data locations for each month.
If you have any additional questions or require further clarification, please, do not hesitate to tell me.
I attached my table, any advice is highly appreciated, Thank you.
