I am wanting to make a graph of annual max NDVI and mean annual temperature, like Figure 2 in this paper: Raynolds, M., Magnússon, B., Metúsalemsson, S. and Magnússon, S.H. (2015) Warming, sheep and volcanoes: Land cover changes in Iceland evident in satellite NDVI trends. Remote Sensing, 7 (8). Pp.9492-9506. - I am aware that they have used GIMMS and I am using MODIS data.

My issue is that when I look at my MODIS geotiff files in ArcMap, my values are not like theirs. I can view the maximum, mean and standard deviation in the properties tab but none of these are decimals. For example, the maximum of my 2010 MODIS file is 9994, the mean is 4433.79 and the standard deviation is 2647.54. My table looks like Table 1 here: ABoVE: MODIS-derived Maximum NDVI, Northern Alaska and Yukon Territory for 2002-2017 (ornl.gov) https://daac.ornl.gov/ABOVE/guides/Alaska_Yukon_NDVI.html

How do I get these values to be decimals? I know it is not simply scaling them by 0.0001 (the MODIS scale factor) as the values in Figure 4 in the link above are not the same as the values for the corresponding year in Table 1.

I am using MYD13Q1 250m

I hope that makes sense - I am extremely stuck and cannot figure it out. Please help!

I have included the tables and graphs if you cannot access them
