OBSIP instrument supply and demand

Requests

Comparison of OBSIP instrument requests and instrument numbers. Request data are derived from submitted OBSIP request forms from 2005 to mid-2009 and include requested instrument numbers and deployment periods. Although the instruments appear oversubscribed by a factor of two, this is an underestimate as it assumes a 2-month instrument turnaround between experiments.
