Of note, there is an Earth observation instrument, RapidScat, being carried in the Dragon's trunk, which will be (has been?) plucked off the capsule by operators on the ground. This one measures wind. Another, called CATS, will be similarly deployed on the outside of the ISS in December-ish; it will measure clouds and aerosols.

These are part of a collection of low-cost (well, lower than a full satellite) Earth observation instruments to take advantage of the external mount points on the ISS. NASA recently had a media briefing about this: http://www.nasa.gov/press/2014/september/nasa-hosts-media-br...
