A global 80-member ensemble reanalysis was created using the finite volume CAM4.0.1 (26 levels) at 2-degree resolution using all the observations that were used in the NCEP/NCAR Reanalysis. The reanalysis extends from 01-Dec-1997 through 31-Dec-2010 at 6-hourly resolution. The reanalysis experiment name was "POP_force" which history has shown to be too narrow in scope. The products generated from this experiment are useful in a much broader sense.
The full dataset is many Tb's of data and is stored on the NCAR/UCAR High Performance Storage System (HPSS). Just the surface fields of variables useful in providing a 'data atmosphere' to Community Earth System Model (CESM) mode components are more than 1.2 Tb.
The POP_force data sets were generated to provide ensembles of atmospheric forcing (from CAM4) to ocean assimilations (using POP). They have also been used to force land model assimilations (using CLM4.0). There are several data products, which are described in detail below:These assimilations are organized as follows.
All of the data sets are on NCAR's HPSS in
hpss:/home/raeder/RAEDER/DAI/POP_force
(Note: this will be shortened to {hpss} for the remainder of the document).
There are several separate assimilations named
POPyy, where
yy = 12,15,74,79,84,89, or 94.
12 and 15 both refer to multiyear assimilations that jointly cover 1997/12/1 - 2010/12/31.
74,79,84,89,94 refer to years 1974, 1979, etc.
In each POPyy directory there is a series of directories named
obs_####, where #### refers to the day within the assimilation
series (padded with leading zeros)
obs_####/diagnostics.tar.gz has DART output: Prior_Diag.nc; Inflated prior ensemble of state vectors ('copy's 3,...,82) at hours 6Z, 12Z, 18Z, 24Z. Also contains the ensemble mean (copy 1) and spread(2), and inflation(83) and inflation standard deviation(84). The state vector is PS, T, US, VS, Q, CLDLIQ, and CLDICE. Posterior_Diag.nc; Same, but for not-inflated posterior ensemble.
2) obs_####/diagnostics.tar.gz also has DART output obs_seq.final; The observations available for assimilation and the ensemble of estimates of those obs. These files can be plotted using DART's Matlab scripts. Some examples are described in 5) The observations consist of T, U, and V from the NCEP BUFR files: radiosondes, ACARS, AIRCRAFT, and satellite drift winds (no surface obs). After 2006 they also used radio occultation observations from COSMIC GPS satellites.
3) Some obs_#### have 'restart sets' in 80xEM/batchN, EM = number of ensemble members/file, (80 members total) N = 1,2,... Each of these files contains the CAM initial files, and CLM, CICE, and DART restart files for EM ensemble members. The CAM initial files contain the posterior model state at the end of the day represented by ####. These are slightly out of balance due to the perturbations introduced by the last assimilation. An example script (hpss2restart.csh) is available for downloading and unpacking these files. You must have an account on the HPSS for this method.
4) "Stream files", which are the data source from which the coupler imported atmospheric forcing for use by other components in CCSM (circa 2011). 1 member and 1 year/file. 48 exist. Up to 80 could be made. {hpss}/POPyy/Forcing_YYYY/ FV2deg_Cplr_out_single-POP15-EM.cpl.ha2x1d.gztar YYYY = 2000,...,2010 EM = 1,...,48 These contain files: FV2deg_Cplr_out_single-POP15-EM.cpl.ha2x1davg.2000.nc: 365 time slots: daily FV2deg_Cplr_out_single-POP15-EM.cpl.ha2x1dx6h.2000.nc: 1460 time slots: 4/day Those files were constructed from contents of {hpss}/POP15/cplr_forcing_YYYY_Mon.gztar YYYY = 2000,...,2010 Mon = Jan, Feb... which contain files 6hourly/FV2deg_Cplr_out_single-POP15-EM.cpl.ha2x1dx6h.2000-4.nc daily/FV2deg_Cplr_out_single-POP15-EM.cpl.ha2x1davg.2000-4.nc EM = 1,...,80 These are intermediate (monthly) files between what was written by CAM/cpl (6 hourly) and what was needed by other component assimilations (yearly). The original files can be found in {hpss}/POPyy/obs_####/H_cplr.ha2x1d.gz.tar #### and yy are as above
5) Observation space diagnostics. Time series and vertical profiles of statistics of the ensemble estimates of the observations can be found in {hpss}/POP15/YYYY_Mon_obs_diag.gztar YYYY = 2000,...,2010 Mon = Jan, Feb, ... These were generated by $dart/diagnostics/matlab/plot_rmse_xxx_evolution.m ......................../plot_rmse_xxx_profile.m with 'totalspread' and 'bias' passed in the argument lists. The statistics are calculated for the northern and southern extratropics, the tropics, and North America.
