CESM2 cloud locking suite single-level fields

Selected single-level Community Atmosphere Model version 6 (CAM6) fields from four simulations of the Community Earth System Model version 2.0.1 (CESM2).  Names of the simulations as they appear in the GRL manuscript (and corresponding native case name) are: CTL (B1850_c201_CTL), CLOCK (B1850_c201_CLOCK), FCTL (F1850JJB_c201_CTL), and FLOCK (F1850JJB_c201_CLOCK).  Note that CLOCK only spans 24 yr while the others span 25 yr. All simulations are forced by prescribed pre-industrial atmospheric composition. CTL and CLOCK use prognostic atmosphere, ocean, land, and sea ice models;  FCTL and FLOCK use prescribed monthly mean sea-surface temperatures and sea ice concentrations taken from CTL. In CLOCK and FLOCK, cloud properties seen by the radiation scheme are prescribed ("locked") and are sourced from randomly selected years of a 3-year data pool comprised of Years 20-22 of CTL.
