description

This zip file contains the final corrected data that were used for the journal article "Observations of molecular hydrogen mixing ratio and stable isotopic composition at the Cabauw tall tower in the Netherlands" by Batenburg et al., Atmospheric Environment, 2016, doi:10.1016/j.atmosenv.2016.09.058   Please cite the original AtmosEnv article when using these data. The paper also contains more information about how these data were collected and calibrated, and on how the quality control flags were assigned. All samples were collected at the Cabauw tower, at the CESAR site (51.971° N, 4.927° E, http://www.cesar-observatory.nl/). H2 and deltaD(H2) are calibrated using one to four laboratory reference air cylinders, depending on measurement period. The H2 mixing ratio of the reference cylinders was determined by UHEI-IUP, MPI-BGC, or the IMAU isotope laboratory. The deltaD(H2) of the reference cylinders is, sometimes indirectly,  linked to the VSMOW scale by measurements of air mixtures containing H2 standards of known isotopic composition. H2 scale: MPI2009, Jordan and Steinberg, AMT, 2011, doi:10.5194/amt-4-509-2011 deltaD(H2) units: permil deviation from VSMOW, Gonfiantini et al., IAEA-TECDOC-825, IAEA Times are UTC.  The corresponding author can be reached through annekebatenburg@gmail.com for questions.
