Purpose: FLUXNET-CH4 is an initiative led by the Global Carbon Project, in close partnership with AmeriFlux and EuroFlux, to compile a global database of eddy covariance (EC) methane flux measurements.
Abstract: Data are standardized, post-processed (i.e., partitioned and gap-filled), and released as FLUXNET-CH4 (Delwiche et al. 2021, Knox et al. 2019). FLUXNET-CH4 Version 1.0 includes data from 81 sites, representing freshwater, coastal, upland, natural, and managed ecosystems. The near continuous, high-frequency nature of EC measurements offers significant promise for improving our understanding of ecosystem-scale CH4 flux dynamics.
The FLUXNET-CH4 Community Product includes a file containing select metadata for each site, including site personnel, location, climate and biome classification, among others. Additionally, each site has 6 metadata columns related to site vegetation. The FLUXNET-CH4 sites were assigned vegetation classifications using a 1) presence/absence, designated by Avni Malhotra based on site literature and 2) dominant vegetation based on a questionnaire sent to lead site investigators. For both presence/absence and dominant vegetation, the following plant functional types (PFTs) were considered: brown mosses, Sphagnum mosses, ericaceous shrubs, aerenchymatous plants, and trees. See Delwiche et al. 2021 methods for a detailed description.
Supplemental Information Summary: We now welcome data submissions for FLUXNET-CH4 V2.0. FLUXNET-CH4 V2.0 will be subject to the CC-BY-4.0 data policy (https://fluxnet.org/data/data-policy/). However, an embargo of two years could be considered for CH4 fluxes under certain circumstances. This would be assessed on a case-by-case basis with the site PIs.
