 Folks:

 I am going to piggyback a related issue on this ticket ....

 On GOES-R ground, some of the data we report for a given geographic region
 (i.e. a cell containing many observations) is the percent that a
 particular geophysical quantity exists.

 We were planning on using the cell method "sum" because it generally
 conforms to the definiiton of sum in Appendix E (The data values are
 representative of a sum or accumulation over the cell. This is the default
 method for a quantity that is extensive with respect to the specified
 dimension.)

 The problem with doing this is ...

 Percent is not the same units of the geophysical quantity.  To solve this,
 the units column for the "sum" row in appendix E could be modified to
 allow percent.

 Another option may be to treat "percent" as a cell method.

 Comments appreciated.

 very respectfully,

 randy
