Electric-Magnetic-Waves Resident Archive for Polar (EMWRAP)

EMWRAP is a NASA-sponsored resident archive (RA) for the Electric Field Instrument (EFI), Magnetic Field Experiment (MFE), and Plasma Wave Instrument (PWI) data collected by the Polar satellite. The main objective of EMWRAP is to maintain the data availability to the scientific community after Polar ended its operation in April 2008. With more than eleven years of observations, Polar sampled all the regions of the magnetosphere inside a distance of 9 Re, and its dataset continues to be valuable for magnetospheric research through the use of these data either alone or with other joint observations. In this presentation we demonstrate the existing capability of disseminating Polar EFI, MFE, and PWI data, and we also describe the ongoing efforts to construct the RA, such as: (1) Establishing a central web server and two backup servers, each equipped with the entire data archive to safeguard against data loss; (2) Generating documentation for the data sets following widely accepted standards, and archiving the expertise in data interpretation for the use by future researchers; (3) Providing the metadata to fully integrate with the Virtual Magnetospheric Observatory (VMO) and other components of NASA's Heliophysics Data Environment (HPDE). When these essential functions are established, a copy of the data products and documentation will be submitted to NSSDC for permanent archives.
