-      <description>Methane emitted from the surface, generated by biomass burning (fires). Positive direction upwards.
-The surface called &quot;surface&quot; means the lower boundary of the atmosphere. &quot;Upward&quot; indicates a vector component which is positive when directed upward (negative downward). In accordance with common usage in geophysical disciplines, &quot;flux&quot; implies per unit area, called &quot;flux density&quot; in physics. The chemical formula for methane is CH4. The mass is the total mass of the molecules. The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. &quot;Emission&quot; means emission from a primary source located anywhere within the atmosphere, including at the lower boundary (i.e. the surface of the earth). &quot;Emission&quot; is a process entirely distinct from &quot;re-emission&quot; which is used in some standard names. The term &quot;fires&quot; means all biomass fires, whether naturally occurring or ignited by humans. The precise conditions under which fires produce and consume methane can vary between models.</description>
