  1. Direct Broadcast Jasmine NahorniakOregon State University

  2. What is Direct Broadcast? Data streamed in real-time from the satellite to the earth as soon as the data are collected. NASA What is Direct Readout? Data collected by a satellite dish in real-time from a satellite travelling overhead.

  9. How is this different from “normal” data? NASA image • NASA Aqua Example • Aqua circles the earth 14 times a day. • Data for an entire orbit is stored on the satellite and then dumped down to two main ground stationsas the satellite passes over them: • Poker Flat, Alaska Svalbard, Norway • An entire orbit of data is then sent to NASA for processing. These data are not available in real-time.

  10. Why use direct broadcast data?

  11. Who needs ocean direct broadcast data? • pollution monitors • oil spill cleanup • research vessels • search and rescue • natural disaster monitoring • fisheries and aquaculture?

  12. For more information .... International Direct Readout Ocean Steering Committee Jasmine Nahorniak (OSU), Ricardo Letelier (OSU), Frank Muller-Karger(USF), Ichio Asanuma (TUIS, Japan), Edward King (CSIRO, Australia), Marcelo Colazo (CONAE, Argentina)e-mail: IDROSC@coas.oregonstate.edu Community Website oceandirectreadout.org OSU Direct Broadcast StationMODIS (SeaDAS): http://sugar.coas.oregonstate.edu/MODIS/ MODIS (IPOPP): http://sugar.coas.oregonstate.edu/MODIS/IPOPP/

  13. support for direct broadcast data • NASA Direct Readout Laboratory (DRL)http://directreadout.sci.gsfc.nasa.gov/ • Patrick Coronado, Kelvin Brentzel • a voice for the direct readout community • source of information • develop software for direct readout data processing • e.g. IPOPP: International Polar Orbiter Processing Package The NASA DRL is seeking input from end-users of ocean satellite data to determine possible future directions.

  14. Discussion: Direct Broadcast • Do you currently use direct broadcast data? • How is direct broadcast data useful to your field? • Can it be improved? MODIS AQUA May 31, 2013 collected at OSU
