DYNAMO-ISS | Earth Observing Laboratory

The Earth Observing Laboratory deployed two Integrated Sounding Systems (ISS)for the DYNAMO field campaign in the Indian Ocean. The two ISS were deployed on the island on Diego Garcia and onboard the R/V Revelle in the central Indian Ocean from October 2011 to early 2012, along with much other instrumentation from many other groups. The ISS used wind profiler radars, radiosonde soundings, and other instrumentation to provide near-continuous profiles of atmospheric motion and thermodynamics at two corners of a sounding array.
