Generate a column providing a unique ID string, such as "EWLD1_2021_UI_top" for ELWD1, 2019, under ice season, top of the water column. This ID will serve as an identifying string, and a basis for table joins to other datasets and other data manipulations. Despite being dynamically generated each time the data output is generated, the ID string needs to be stable: the row "EWLD1_2021_UI_top" needs to be exactly that string from year to year.
