UKCA model output using the CRI-Strat mechanism

Processed UKCA model output data to accompany "The Common Representative Intermediates Mechanism version 2 in the United
Kingdom Chemistry and Aerosols Model" by Scott Archer-Nicholls et al., to be published in the Journal of Advances in Modeling Earth Systems (JAMES), submitted 2020.

Data has monthly averages over the 9 years of model integration (2010-2018) for all prognostic and diagnostic variables used for analysis in the main paper. The model was run with four separate suites, corresponding to the four main scenarios evaluated in the main paper and summarised in Table 4 of the paper. The suite codes match with the scenarios as follows

* bt564: StratTrop, the Base stratTrop scenario

* bt680: CRI_Emiss_ST, the CRI-Strat scenario with StratTrop emissions, used for isolating the effect of chemical representation without changes to emissions

* bp480: CRI_Emiss_C2C3, the CRI-Strat scenario with speciated C2-C3 emissions, used for isolating the effect of NMVOC speciation without changing the total emitted mass.

* cc182: CRI-Strat, the Base CRI scenario
