  This is CT-NRT version 2015-2.  Results updated from v2015-1 start
  in 2013-12-14 (although results from 2012-06-09 through 2013-12-14
  from CT-NRT v2015-1 are mirrored here for convenience).  Simulation
  begins from the CT-NRT v2015-1 optimized CO2 fields.  Prior flux
  model is climatology of optimized CT2013B ocean, land, and wildfire
  fluxes, Miller 20150715 fossil fuels, and a land biosphere CO2 flux
  anomaly driven by anomalies of ERA-interim shortwave radiation and
  temperature, and GPCP v2.2 precipitation.

  Optimization is done using data from
  obspack_co2_1_CarbonTracker-NRT_v1.0_2015-10-06 as collated in
  prepped_adaptive_NRT_20151007_20151007170933.  Optimization uses
  standard CT methods.

  Updated CT-NRT v2015-2 to extend through 2015-11-27.  New NRT
  ObsPack obspack_co2_1_CarbonTracker-NRT_v2.0_2016-02-12 was used for
  the optimization.  This ObsPack does not include Environment Canada
  in situ data, so there were many fewer observational constraints in
  Canada starting on 2015-07-25.  All other methods were held
  constant, so the version number was not incremented.
