Methane Clumped Isotopologues Database for POLYGRAM

The database was made as a part of POLYGRAM project (NE/V007149/1). The database aims to summarise the state of double substituted methane isotopologues (know also as clumped isotopologues, Δ13CH3D and Δ12CH2D2) measurement research, with an emphasis on compiling results of all relevant work and aid development of the inputs to atmospheric modelling studies. The compiled database comprises 1241 data records from 63 peer-reviewed articles. Database includes both field samples and laboratory experiments from numerous laboratories worldwide.

This database is made freely available to the scientific community. The database has a Digital Object Identifier (DOI).
