Sentence examples for mass of ash from inspiring English sources
The findings provide evidence that a 3-kilometer-deep blanket of pollution--a mass of ash, acids, aerosols, and other particles--is disrupting weather systems in western Asia.
TEPHRA2 is a Eulerian dispersal model that assumes an initial released mass of ash distributed between the ground and the plume top for a single event (Bonadonna et al, 2005).
Here, this fraction was used because of the relatively-coarse nature of most of the samples (and, hence, the mass of ash required to separate sufficient respirable material was beyond the mass available for the INGV samples).

Between April 2013 and February 2014 there were only four eruptions at Sakurajima volcano for which there were sufficient observations to allow us to compare observed and predicted masses of ash generated.
Although our estimate was accurate for the largest of these eruptions (16 31 JST on August 18 , 2013, which generated an ash plume that rose 5000 m above the crater, we underestimated the masses of ash for the three smaller eruptions, which had plume heights of 2400 3300 m.
Volcanic plumes transport large masses of ash and magmatic gases high into the atmosphere (Sparks et al. 1997).
The mass fraction of ash for each substrate was determined, multiplied by 100, and expressed as mass percentage.
