Description

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.

Project

Large Scale Biosphere-Atmosphere : The Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) is an intensive scientific investigation of the tropical rainforest of Brazil and portions of adjacent countries. Like FIFE and BOREAS, this project uses intensive remote-sensing techniques and ground-based experiments to investigate the atmosphere-biosphere-hydrosphere dynamics of this large tropical region. The LBA Project encompasses several scientific disciplines, or components. The LBA-ECO component focuses on the question: "How do tropical forest conversion, regrowth, and selective logging influence carbon storage, nutrient dynamics, trace gas fluxes, and the prospect for sustainable land use in Amazonia?"
