We have identified points where CVM-S4 queries are stateful, specifically in the GTL region (~100m depth). By this, we mean that if we query the same point twice, CVM-S4 (and UCVM) returns different Vp, Vs, and rho properties for each query.
To investigate this, we will run some tests to determine if all CVM-S4 regions are stateful, or only the GTL regions. We will also look at how large the differences
Initial Observed Differences
Search Regions =
Define two search regions, one in LA Basin where CVM-S4 has a GTL define. The second in the mojave where it is CVM-S4 background model. We will discretize at ~10.0m resolution. Basedon this link: Decimal Degress, we'll descritze at 0.00001 resolution.
