|Dataset||LBA-ECO TG-04 Radon Activity at Forested and Pasture Sites, Para, Brazil: 2000-2004|
|Project||Large Scale Biosphere-Atmosphere Experiment (LBA-ECO)|
|Time period||2000-01-01 to 2004-12-09|
This data set provides measurements of Radon-222 activity in air, within and above the vegetation canopy at two flux tower sites in the Tapajos National Forest -- the km 67 forested site located in undisturbed old-growth (primary) forest and the km 83 logged forest site, and a third flux tower site -- the km 77 pasture tower site on BR-163 just south of the city of Santarem, Para, Brazil. Measurements were made over various intervals from 2000 to 2004.. Continuous Rn-222 activity profiles within and above the forest canopy were measured with detector array systems of eight or more flow-through detectors based on a pulse-ionization Rn counting air chamber controlled by custom software. There are 16 data files in comma-delimited (.csv) format with this data set.
