FCE sampling attributes are based on the data fields in FCE datasets.
In some cases, a sampling attribute may have more than one name like rainfall, which can also be called precipitation.
We recommend searching by the more general attribute names first (i.e. carbon vs. total carbon) to see a larger
listing of possible sampling attributes and then narrowing your search for more specific sampling attributes.
The search will return a list of sampling attributes as well as the sites, datasets,
and projects associated with those sampling attributes.
