2 What is Direct Broadcast? NASA Data streamed in real-time from the satellite to the earth as soon as the data are collected. 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 stations as 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 Direct BroadcastNormal Timeliness Accuracy No cost Global coverage Mapped, L3 data Data archive Standard products Why use direct broadcast data?

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

13 support for direct broadcast data NASA Direct Readout Laboratory (DRL) http://directreadout.sci.gsfc.nasa.gov/ 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 MODIS AQUA May 31, 2013 collected at OSU Do you currently use direct broadcast data? How is direct broadcast data useful to your field? Can it be improved? Discussion: Direct Broadcast
