SPARC Reanalysis Intercomparison Project (S-RIP) reanalysis common grid files

This is the reanalysis common grid data set produced as part of the SPARC (Stratosphere-troposphere Processes and their Role in Climate) Reanalysis Intercomparison Project (<a href="https://s-rip.ees.hokudai.ac.jp/">S-RIP</a>). These data have been used in several chapters in the S-RIP report, including Chapter 4 (Overview of Ozone and Water Vapour - See <a href="http://doi.org/10.5194/acp-17-12743-2017">Davis et al., ACP, 2017</a>) and Chapter 8 (Tropical Tropopause Layer - See <a href="https://www.atmos-chem-phys.net/20/753/2020/">Tegtmeier et al., ACP, 2020</a>). Notes about this data set:     - Data set size: ~26 GB     - Reanalyses included are CFSR, ERA-I, JRA-25, JRA-55, MERRA, MERRA-2     - Variables include T (variable name ta), u (ua), v (va), O3 (tro3), WV (hus), and GPH (zg)     - Data are based off of the ana4mips data set     - Data are on a 2.5° x 2.5° grid     - All values are monthly means     - Pressure levels are (1000, 925, 850, 700, 600, 500, 400, 300, 250, 200, 150, 100, 70, 50, 30, 20, 10, 7, 5, 3, 2, 1, .7, .5, .3, .1 hPa)     - 3 time periods are provided:         - The “full” time period (different for each reanalysis)         - The “S-RIP base period” (i.e., 197901-201312)         - The “climatology” period (198101-201012)     - Both 3D (lon,lat,level) and zonal mean 2D (lat, level) files are provided     - Both timeseries and climatology data are provided. Files with “ltm” in the name are climatologies     - Reanalysis “Ensemble” files are located in the /ensemble directory (See note below*) *Regarding the “ensemble” data — I highly recommend using the “ensemble” files in the “ensemble” folder for climatological intercomparisons. You can use a single file (e.g., hus_Amon_reanalysis_ENS_198101-201012.cg.ltm.nc for water vapor) that contains the climatologies for each reanalysis. The data in these files are of dimension (lon, lat, level,time(==12 months ), “record”), where record 0 = CFSR, 1=ERA-I, 2=JRA-25, 3=JRA-55, 4=MERRA, 5=MERRA2. There is also a corresponding “ensemble mean” file (e.g., hus_Amon_reanalysis_ENS_198101-201012.cg.ltm.ensmean.nc) that is simply the ensemble mean climatology from the 4 core reanalyses (CFSR, ERA-I, JRA-55, MERRA — EXCLUDING JRA-25 & MERRA2).
