how to calculate monthly averages from daily averages of MODIS Data?

I am Mustapha and a master of Meteorology student at Nanjing University of Information, science and Technology in China. I am currently using Modis Terra and Aqua for my research and to be specific Cloud Fraction Data for the year 2010. I however want to get the monthly averages for this data and I am lost as to how to go about this. Can someone here please assist me with suggestions as to how I can go about this? Thank you.

Do you have a specific coding question?

Answer 1

If you are using newer version of Matlab(2016 or later), use timetable

https://www.mathworks.com/help/matlab/ref/timetable.html

Then you could calculate monthly mean with retime like,

TT_mean = retime(your_timetable,'monthly','mean')

For older versions, use a normal table and then varfun like,

montly_mean = varfun(@mean,your_table,'GroupingVariables','Month_No')
