I have got a set of data for global PM2.5 conc., but the data is in .adf format, within folders info and 'filename', I am able to open the file in Arc Map, what i need is the original data for each grid point according to which the plot is made,
I tried to export the data to some other format, but none of the formats are providing grided data set.
Please help me out.
