TSANA System -- an EPIC derivative for in-situ dataset queries and downloads

In-situ oceanographic datasets have been widely used by researchers for analysis and by modelers for assimilations. The Asia-Pacific Data-Research Center (APDRC) has been serving in-situ data using the EPIC system developed at the Pacific Marine Environmental Laboratory (PMEL). The APDRC maintains an archive of 3 million profile datasets from Argo, WOCE-WHP (World Ocean Circulation Experiment, WOCE Hydrographic Program), US GODAE/FNMOC (Global Ocean Data Assimilation Experiment/ Fleet Numerical Meteorology and Oceanography Center) and WOCE-UOT (Upper Ocean Thermal). Our in-situ time series datasets include NCAR DSS rainfall, Pacific Island rainfall and WOCE current meter datasets. With recent improvements the Java Ocean Atlas and increasing demand from users who want to select a subset of these datasets, we have developed an EPIC derivative called the TSANA System. TSANA System allows users to query its database and to make a package of selected datasets for downloading. The package is a tar file containing all the selected datasets along with an inventory file (also known as a pointer file). Currently, Java Ocean Atlas is a well-known client software that can be used to analyze datasets downloaded from TSANA. We also provide a simple Matlab script for users to open datasets through the inventory file. To use TSANA System, please visit http://apdrc.soest.hawaii.edu/tsana
