The dependence of deep convection on environmental profiles is poorly represented by parcel models of convective clouds. Is there a way to build up a sensitivity function expressing how the profile of convective impacts depends on the profile of environmental conditions? This function is a matrix in the linearized problem, more definite and clear than a parameterization as it is usually thought of. Is there a role for observations in such a matrix estimation? Might it make testable (falsifiable) predictions, allowing an indirect role for abundant, routine large-scale observations in constraining our understanding of convection's sensitivity function?
The Integrated Data Viewer (IDV) from Unidata is a way of exploiting the huge and growing abundance of OpenDAP datasets sitting on remote servers. It allows a user to bypass the download-and-curation steps of building up individual local copies of data collections. After slogging through IDV's many complications and frustrations, a clean simple pathway has now been devised for new users to get a successful quick start.
