In addition, Forman’s tool also includes a “dollars-to-science” cost estimate tool that allows researchers to assess the financial risks associated with a proposed mission. Forman explained that while these indirect observations of freshwater include valuable information for quantifying freshwater, they also each contain their own unique error characteristics that must be carefully integrated with a land surface model in order to provide estimates of geophysical variables that scientists care most about.
“It’s nice to be part of a big team because these are big problems, and I don’t know the answers myself. I need to find a lot of people that know a lot more than I do and get them to sort of jump in and roll their sleeves up and help us. And they did,” said Forman.
