Methane doubly substituted (clumped) isotopologues database

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 complied database comprises 1475 data records from 75 peer-reviewed articles. Database includes both field samples and laboratory experiments from numerous laboratories worldwide.
