The ORNL DAAC recently released an update to the following LBA-ECO dataset by Restrepo-Coupe, N., et al. (2021):

LBA-ECO CD-32 Flux Tower Network Data Compilation, Brazilian Amazon: 1999-2006, V2

This dataset is a compilation of carbon and energy eddy covariance flux, meteorology, radiation, canopy temperature, humidity, CO2 profiles and soil moisture and temperature profile data that were collected at nine towers across the Brazilian Amazon. Independent investigators provided the data from a variety of flux tower projects over the period 1999 thru 2006. This is Version 2 of the tower data compilation, where the data have been harmonized across projects, additional quality control checks were performed, and have been aggregated to hourly, daily, 16-day, and monthly timesteps. This integrated dataset is intended to facilitate integrative studies and data-model synthesis from a common reference point.

This dataset includes and expands upon Version 1 of this compilation (Saleska et al., 2013). Version 2 contains the flux tower data and additional calculations of ecosystem respiration, gross ecosystem productivity, and canopy storage as published in Restrepo-Coupe et al., 2013.

The Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA-ECO) was an intensive scientific investigation of the tropical rainforest of Brazil and portions of adjacent countries. LBA used intensive remote-sensing techniques and ground-based experiments to investigate the atmosphere-biosphere-hydrosphere dynamics of this large tropical region. 

Additional data from LBA-ECO and other relevant links can be found on the ORNL DAAC's LBA-ECO Project page .
