05 June 2015 CESM1-CAM5 and CCSM4 sstClim and sstClim4xCO2, all files Incorrect SST climatology file used Will be corrected and re-run TBD
24 Mar 2015 CCSM4 abrupt4xCO2, all files CO2 in r1 is correct - 4 * 284.7ppm
CO2 in r2 is different - 4 * 355ppm. Use with caution.
TBD TBD
22 Dec 2014 CESM1-CAM5 All historical*, all files forcings metadata in error - these runs have sulfate indirect (SI) and sulfate direct (SD) forcings time-evolving, so "SD" should be "SA" Not to be corrected 22 Dec 2014

Values represent average so time must be midpoint of 3-hour interval, not endpoint
Solution: shift time coordinate by -90 minutes

24 Feb 2013 CESM1-CAM5 historical, rcp26, rcp45, rcp60, rcp85 Incorrect parent_experiment_rip for all RCP data:
rcpNN_r1i1p1 incorrectly given parent_experiment_rip of r3i1p1
rcpNN_r2i1p1 incorrectly given parent_experiment_rip of r1i1p1
rcpNN_r3i1p1 incorrectly given parent_experiment_rip of r2i1p1
Corrected
All rcpNN parent_experiment_id now match.
