[CF-metadata] searching CF-Metadata list

2014-09-03 Thread John Graybeal
I too have often been frustrated with the on-line archive search capabilities. The suggestion below (search by yearly archive file) is useful only if the topic is discussed entirely within a year, and you know which year that was, and it was a year after 2005 (since years 2002-2005 show "Gzip'd

While I agree it is not a big problem to use at_or_above_threshold in this and whatever other standard names eventually are needed, discoverability would be better with the boolean attribute ("comparison_includes_equality"?). As a practical matter, people looking for, e.g., number_of_days_with_

Hi Reyna, Yes, this is in scope for CF. There is a standard name height_above_sea_floor (no definition, canonical units meters) which has the meaning you need, if you use a negative number for the distance your data is below the sea floor. If this is not ideal, possibly we could add depth_be
