 ## Summary
 
+**Credits** This tutorial is based on code provided by Cara Thompson at New Mexico State University. It has been modifed slightly and converted into a tutorial by NSIDC. 
+
 In this tutorial we demonstrate how to download SNODAS data from the NOAA@NSIDC HTTPS File System and select one variable and compile it into a RasterStack for quick visualization and save as a .grd file. Please note that the tutorial demonstrate processing masked files from after October 2013. If you wish to process any masked files prior to October 2013 or any unmasked files you will need to modify the tutorial slightly, details on how to do this are included in the tutorial.
