I'm using the TRMM 3B43 precipitation data. I have downloaded individual NetCDF files depicting yearly accumulation in mm for each year from 2000 to 2015 (16 files). I have imported each file into ArcGIS as a raster file, and each shows a different min & max. I now want to calculate the average annual precipitation from 2000 to 2015. How would you recommend I do this?
( "raster_1"+"raster_2"+...+"raster_n" )/n
Where n is the number of rasters.
