In response to the science questions, the experimental design will characterize the region in its natural state and in states perturbed by regional and global human activities. Five ground sites are strategically located around the Manaus region (see the map for more detailed information on the measurements at each location):
- T0 - Amazonian Tall Tower Observatory (ATTO)
- T1 - National Institute for Amazonian Research in Manaus
- T2 - Iranduba
- T3 - Manacapuru
- ZF2 - TES Measurement Sites north of Manaus and Manacapuru.
Two intensive operational periods—the first from 1 February to 31 March 2014, and the second from 15 August to 15 October 2014—will be conducted to collect additional observations. During these intensive periods, aerial measurements will complement the ground-based measurements for two six-week periods. The ARM Aerial Facility (AAF) G-1 will be deployed for in situ measurements of trace gas and aerosol properties beginning 15 February and 1 September.
