Alignment with AmeriFlux

AmeriFlux is the network of eddy covariance flux sites in the Americas, supported by the DOE Environmental System Science program (https://ess.science.energy.gov/ameriflux/). Its data products name their variables with short codes such as FC, SWC or NEE_VUT_REF. This page records how each code maps to BERVO. The work is tracked in issue #178 and added in slices.

Decisions

These were settled on issue #178 and its pull requests.

  1. Scope. Every AmeriFlux variable and concept is in scope. BADM fields that record dates, methods, comments, contacts or instrument settings describe a dataset rather than a quantity, and are left out.
  2. EcoSIM terms tied to the model are left as they are. Where BERVO's only match was an EcoSIM variable defined for the model, such as the grid-cell Net ecosystem carbon dioxide exchange (BERVO:0000326, in g.h-1/{grid}), a tower-level term was added beside it, and the EcoSIM term was given the new term as an additional parent.
  3. Variants. A variant that is a physically different quantity gets its own term: a mole fraction in wet air or in dry air, a turbulent flux or a storage flux. A variant that is a statistic or a flag does not: a _SIGMA variable is its base term with the Standard deviation qualifier, WS_MAX its base term with Maximum, and the nine *_SSITC_TEST flags share one term.
  4. Codes are related synonyms, not cross-references, since AmeriFlux has no web address for a variable and a code is not an exact synonym. A code that is already the label, symbol or synonym of another BERVO term, case-insensitively, is recorded only in Comment, with the reason, because as a synonym it would lead text matchers to the wrong term. Examples are the chemical formulas CO2 and O3, and H (Hydrogen), LE (Effective leaf area index), SB (Antimony), SC (Clayey sand), P (Phosphorus) and SR (Strontium). Every term records its code in Comment either way.
  5. FLUXNET processed variables get no term each. BERVO adds the concepts that describe the processing and the few base quantities it lacked. The table below resolves each FLUXNET variable to a base term plus those concepts.
  6. BADM variants by layer, organ or live and dead status take one generic term per quantity, with the variant in contexts or qualifiers, as the current BADM standard itself does.
  7. BADM value lists become concepts: IGBP land cover, Köppen climate, and the BADM vegetation-type, phenology-event and disturbance lists.

Placement settled along the way:

  • Tower gas mole fractions sit under Atmospheric composition variable (BERVO:9000048), not under the EcoSIM forcing group Atmospheric gas concentration.
  • Turbulent and storage fluxes sit directly under Surface flux variable, because the generic flux terms, such as Carbon dioxide flux, are defined as exchange at the surface. Net ecosystem exchange is such an exchange and sits under Carbon dioxide flux.
  • Fractions take BERVO's 1 even where AmeriFlux reports percent; the term's Comment says so.

FP-Standard base names

145 of 145 base names resolve to a BERVO term. How says whether the code is a synonym on the term, recorded only in its Comment (decision 4), or expressed as the term plus a qualifier (decision 3).

FLUXNET FULLSET variables

Concepts and base terms added

Term Parent Describes
BERVO:8001089 Gap-filling method Method
BERVO:8001090 Marginal distribution sampling Gap-filling method FLUXNET FULLSET suffix: _MDS. Described by Reichstein et al. (2005), Global Change Biology 11:1424-1439.
BERVO:8001091 Reanalysis downscaling Method FLUXNET FULLSET suffix: _ERA, for values downscaled from the ERA reanalysis. Placed under Method rather than Gap-filling method because downscaling is not in itself gap-filling: FLUXNET uses the downscaled series to fill gaps in the _F variables, but the _ERA variables are the downscaled values themselves.

BERVO:8001096 Energy balance closure correction Method FLUXNET FULLSET suffix: _CORR.

BERVO:8001100 Joint uncertainty Error range FLUXNET FULLSET suffix: _JOINTUNC.
BERVO:8001101 Percentile Quantitative value FLUXNET FULLSET suffixes: _XX, a placeholder for the 05, 16, 25, 50, 75, 84 and 95 percentiles of the ensemble of estimates made with different friction velocity thresholds, and the bare _25 and _75 of the H_CORR and LE_CORR variables, which FLUXNET describes as their 25th and 75th percentiles.
BERVO:8001102 Reference ensemble member Quantitative value FLUXNET FULLSET suffix: _REF, chosen among the 40 estimates made with different friction velocity thresholds.
BERVO:8001103 Daytime Time FLUXNET FULLSET suffix: _DAY. Flux processing counts as daytime the periods when the potential incoming shortwave radiation is above zero.
BERVO:8001104 Nighttime Time FLUXNET FULLSET suffix: _NIGHT. Flux processing counts as nighttime the periods when the potential incoming shortwave radiation is zero. No cross-reference: no OBO class for night was found in NCIT or ENVO, though Daytime has NCIT:C64928.
BERVO:0002323 Potential incoming shortwave radiation Incoming radiation FLUXNET FULLSET variable: SW_IN_POT. Placed under Incoming radiation, not Incoming shortwave radiation, because it is computed for the top of the atmosphere rather than measured at the land surface; Incoming radiation is the nearest parent that does not place it at the land surface.
BERVO:0002324 Friction velocity threshold Meteorological variable FLUXNET FULLSET does not report the threshold itself; its constant and variable forms (_CUT, _VUT) and the percentile used (_USTAR50) qualify the NEE, GPP and RECO variables. How it was chosen is recorded by the concepts Constant friction velocity threshold (BERVO:8001097) and Variable friction velocity threshold (BERVO:8001098).
BERVO:0002325 Energy balance closure correction factor Land surface variable FLUXNET FULLSET reports the number of values used to compute it (EBC_CF_N) and the method used (EBC_CF_METHOD), and applies it in H_CORR and LE_CORR. Placed under Land surface variable, the grouping for properties that control the exchange of energy and water at the surface, because it is a ratio rather than a flux.
BERVO:0002326 Nighttime flag Flag data type FLUXNET FULLSET variable: NIGHT. The code is not recorded as a synonym because it is also the label, symbol or synonym of another BERVO term.

Variables

232 of 232 FULLSET variables resolve to a base term and its qualifiers. A _QC variable is a Quality control flag for the variable it names. The list was taken from the FULLSET page, where 3 rows give time-resolution notes rather than variable names; they are not counted. The same names serve every time resolution (half-hourly to yearly), so they are listed once.

BADM site metadata

BADM (Biological, Ancillary, Disturbance and Metadata) records what a site is like: its vegetation, soils, climate, disturbance history and management. The fields come from the BADM standard (https://ameriflux.lbl.gov/data/badm/badm-standards/) and the legacy field list above. Each field of the legacy list was sorted into one of five classes:

Class Fields (legacy list) In BERVO
Quantities and site properties 83 yes
Disturbance and management 16 yes
Measurement metadata: dates, method, statistic, organ, species, depth range, comment 267 no
Administrative: DOIs, team members, addresses, acknowledgement, funding 54 no
Instrument settings (INST_*, INSTPAIR_*) 33 no

Measurement metadata, administrative fields and instrument settings describe a dataset rather than a quantity, so they have no terms. Where a metadata field names a layer, organ or status of a quantity, that becomes contexts or qualifiers on the general term, following decision 6.

Variables

The class counts above are of the legacy list. The table below also has the fields of the current standard that the legacy list lacks, so it has more rows than the two in-scope classes. A legacy code is a field of the older list only. Where the current standard folds several legacy fields into one general field, they map to the general term with the variant in contexts or qualifiers.
