| http://www.w3.org/ns/prov#value | - It never hurts to emphasize that PIOMAS is a model, and even though it???s constrained by observations, I emphasize that PIOMAS is a model on a regular basis, especially when PIOMAS tends to go low, because many people assume that the PIOMAS graph is showing observed data.I always feared that PIOMAS was overestimating volume loss.???
