VAPOR Project

TG GIG PY6 Award:
XD Vis Award:
KISTI Award:
Alan has been working on an isoline renderer in vaporgui, which is planned to meet the isoline requirement of Kisti for 2014. Currently the code is able to render isolines for both 3D and 2D variables, and we are planning to review the usability of this feature
Scott began preliminary work to develop a CAM data reader. CAM output is CF compliant, and thus has similar requirements to MOM4 and ROMS data readers developed previously. The hope is to leverage as much of the earlier code as possible. Toward that end Scott is looking at re-factoring the existing MOM/ROMS reader class objects. The most challenging aspect so far has been the CAM vertical coordinate (which is very different from the Ocean model coordinate systems). CAM uses a “Atmospheric Hybrid Sigma Pressure Coordinate”. Correspondence from Brain Eaton revealed that Z3 cannot be assumed to present in all CAM datasets, so the Z3 vertical coordinate implementation was cast aside
2.x Development:
John ported VAPOR to Mac OS X 10.9 (Mavericks). The new Mac OS has a substantially different programming environment than previous versions.
3.0 Development:
We have had several discussions about Vapor 3.0 plans. Alan reimplemented and simplified the SetValues and GetValues API in the Params library, with support for validating during SetValues as well as including built-in support for Undo and Redo.

Education and Outreach:
Scott organized and presented a VAPOR webinar in March. Judging from attendance statistics and viewer feedback, the event was very successful (despite a number of technical glitches using ReadyTalk).
Software Research Projects
John continued work with Hank Childs, U. of Oregon, to test and evaluate the VDC 2 data format in the context of preserving various results of various analytical operators applied to homogenous turbulence. Hank's grad student, Samuel Li, is conducting the actual tests.
Production Visualization Services & Consulting
Pete Johnsen of Cray is running a new 500m WRF run for ERICA IOP4 (a severe Atlantic storm in January 1989) on Blue Waters, with the expectation that the higher resolution will provide new insight into the dynamics of this storm. This run will produce several terabytes of data. He has moved some data to NCAR and we are doing initial conversion and visualization to verify that the simulation is OK.
