BIOMASS vs volcalc
A side-by-side editorial comparison of BIOMASS and volcalc — release velocity, themes, recent moves, and the top alternatives to consider.
BIOMASS vs volcalc: at a glance
What is BIOMASS?
A tropical-forest biomass staple modernising its geospatial stack without saying so
BIOMASS estimates aboveground biomass and its uncertainty in tropical forests and is well established in that niche. Its public changelog is close to empty: the most recent entry, 2.2.4, is a thirty-four character pointer to the NEWS file. The last release with readable content, 2.1.11, bundled six versions of work whose substantive part was migrating off sp and raster to sf and terra, and from httr to httr2.
What is volcalc?
Rebuilt itself around SMILES and .mol input, then made the chemistry configurable
volcalc estimates the volatility of chemical compounds from their structure, implementing the SIMPOL.1 group-contribution method and the Meredith et al. variant. Version 2.0.0 severed the package from KEGG: calc_vol() takes .mol file paths or SMILES strings directly, is vectorized over multiple compounds, and the group-contribution maths was split into its own simpol1() function. Work since has been chemistry accuracy and configurability — the full set of SIMPOL.1 functional groups, volatility thresholds for clean atmosphere, polluted atmosphere or soil, user-supplied temperature, and a validate option returning NA when structure parsing looks suspect.

◆ Current state
BIOMASS estimates aboveground biomass and its uncertainty in tropical forests and is well established in that niche. Its public changelog is close to empty: the most recent entry, 2.2.4, is a thirty-four character pointer to the NEWS file. The last release with readable content, 2.1.11, bundled six versions of work whose substantive part was migrating off sp and raster to sf and terra, and from httr to httr2.
◆ Where it's heading
The visible arc is dependency modernisation and CRAN compliance rather than science: retiring sp and raster ahead of their deprecation, failing gracefully when taxonomic services are unreachable, and repeatedly changing taxonomic backend as those services disappeared — taxosaurus to TNRS, then away from Tropicos once it was no longer maintained. The recurring fragility is correctTaxo(), which depends on third-party name resolution outside the maintainers' control.
◆ Prediction
Expect the next release to be another compliance or dependency response; on this feed's record the release notes will not say what changed, leaving the NEWS file as the only reliable source.

◆ Current state
volcalc estimates the volatility of chemical compounds from their structure, implementing the SIMPOL.1 group-contribution method and the Meredith et al. variant. Version 2.0.0 severed the package from KEGG: calc_vol() takes .mol file paths or SMILES strings directly, is vectorized over multiple compounds, and the group-contribution maths was split into its own simpol1() function. Work since has been chemistry accuracy and configurability — the full set of SIMPOL.1 functional groups, volatility thresholds for clean atmosphere, polluted atmosphere or soil, user-supplied temperature, and a validate option returning NA when structure parsing looks suspect.
◆ Where it's heading
The arc runs from a script tied to one database toward a general structure-to-volatility tool. Dropping KEGG from the core in 2.0.0, then removing KEGGREST as a dependency entirely in 2.2.0, took the package from volatility for KEGG compounds to volatility for any structure a user can supply. The accompanying manuscript published in 2023, and the changelog since has been careful about coefficient double-counting — amines and amides have each been corrected — which suggests the group definitions are the part under active scrutiny.
◆ Prediction
The smarts_simpol1 dataset added in 2.2.0 documents how functional groups are defined, pointing toward further estimation methods alongside SIMPOL.1 and Meredith; splitting simpol1() out in 2.0.0 was stated to be groundwork for exactly that.
