Description
LBA-ECO TG-06 contains vertical profile measurements of six atmospheric trace gases—carbon dioxide (CO2), methane (CH4), carbon monoxide (CO), hydrogen (H2), nitrous oxide (N2O), and sulfur hexafluoride (SF6)—collected via light aircraft over three Brazilian sites from December 2000 to November 2005. The data, analyzed relative to international calibration standards, includes profiles over Fortaleza (Atlantic Ocean background air), Santarem (Tapajos National Forest), and Manaus (K34 flux tower). This dataset provides a multi-year, multi-species snapshot of atmospheric composition relevant to the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA).
Use Cases
Analyzing vertical gradients of greenhouse gases (CO2, CH4, N2O) to understand surface-atmosphere exchange processes in the Amazon.
Comparing background air composition sampled over the Atlantic Ocean (Fortaleza) with forest-influenced air at inland sites (Santarem, Manaus).
Investigating co-variation of carbon monoxide (CO) with other gases as an indicator of combustion or pollution influences.
Calibrating or validating regional atmospheric models and satellite retrievals with in-situ profile data from 2000-2005.
Studying the spatial representativeness of flux tower measurements (e.g., km 67, K34) using overflight data.
Strengths
Covers six key atmospheric trace gases measured with internationally accepted calibration standards.
Provides data from a five-year time range (December 2000 to November 2005) across three distinct geographic locations.
Includes both ascending and descending vertical profiles designed to sample background and forest-influenced air masses.
Limitations
Column names and exact row counts are not specified in the available metadata, limiting immediate understanding of data structure.
