LAS was developed by PMEL and is a web server designed to provide flexible access to georeferenced scientific data. LAS enables easy regional subsetting of global gridded products. LAS enables the web user to:

• visualize data with on-the-fly graphics
• request custom subsets of variables in a choice of file formats
• access background reference material about the data (metadata)
• compare (difference) variables from distributed locations

The Open Source Project for a Network Data Access Protocol (OPeNDAP) is a software framework used for data networking. OPeNDAP provides tools for making local data accessible to remote locations regardless of local storage format. Most of our locally-stored datasets are served by a GrADS DODS server (GDS) developed at COLA. We also utilize Unidata's THREDDS (Thematic Real-time Environmental Distributed Data Services) to customize remote datasets via aggregation to allow for more user-friendly access. Data served via OPeNDAP can be directly accessed by the following client-based software:

• GrADS
• Matlab
• Ferret
• FORTRAN code

The EPIC Web Browser is a web application that provides interactive, on-line data access to EPIC hydrographic data sets. It allows users to:

• view in-situ data by creating plots on-the-fly
• generate listings in ASCII format
• download data-files in binary (EPIC/netCDF) format
• view meta-data/attributes of a data-file
• edit pointer file
• download pointer file (only for in-house users)
• plot station locations
• make vertical section plots

TSANA is a derivative of EPIC. It gives users the ability to query our in-situ database and download selected datasets and/or pointer files.

Client software such as Java Ocean Atlas (JOA) and Matlab can be used to analyze the profile data downloaded from the TSANA System. Sample Matlab scripts are available to read the data into Matlab.

To locate datasets in APDRC's holdings, go to the data page. Datasets are searchable by server type, data type, grid type, discipline, source or variables. A list of qualified datasets will be returned. For example:

AMSR-E
Argo

Clicking on the to the left of the dataset name will bring up the dataset's documentation page. Buttons on the right of dataset name indicates which servers are available. Sometimes clicking on the LAS button returns "Welcome to LAS. This session will expire after 180 minutes of inactivity", re-click on the LAS button to go to the appropriate page.
