I, Jiye ZENG, am an research fellow at the Center for Global Environmental Research (CGER), National Institute for Environmental Studies (NIES), Japan. My personal e-mail is <zeng @ zegraph . com> and my e-mail for work is <zeng @ nies . go . jp>.

Having experienced with scientific data processing and management for many years, I decided to develop a library for 3D data visualization a few years ago to overcome difficulties encountered in using various softwares. I have used expensive commercial softwares, such as Matlab, PV-Wave, and IDL; and many freewares, such as DISLIN, PLPLOT, and Octave. All of them are great but lacked some features that can't be added easily; hence comes the idea of ZeGraph and Z-Script and many other libraries.

The Meteorological Data Explorer (METEX) is another free software that I developed for CGER to calculate air trajectory using various meteorological data. I am the system administrator and webmaster of the online calculation server. ZeGraph and Z-Script are being used by METEX application server to handle SOAP and CGI requests.

In addition to maintaining large monitoring databases, my recent works include real-time data download from CGER's UV monitoring stations, calculating UV index from the raw data, making graphs, and uploading the results to the server. All done in Z-Script.

My earlier research involves CO₂ monitoring in the Pacific ocean.
