This is a readme file for the outputs from the NCEP Eta Regional Climate model (RCM). a) Data directory The directory is organized this way: |-README (this file) |-tier1.ctl (GrADS control file for tier1 outputs) |-tier2.ctl (GrADS control file for tier2 outputs) | | |-Tier1 | |-Tier2 |-May_1990 -- |-Tier2_429 | |-Tier2_nobaja | |-Tier1_nobaja | | |-Tier1 |-Jun_1990 -- |-Tier2 | |-Tier2_429 | |-Tier2_nobaja | |-Tier1_nobaja | | |-Tier1 | |-Tier2 |-Jul_1990 -- |-Tier2_429 | |-Tier2_nobaja | |-Tier1_nobaja | | |-Tier1 | |-Tier2 Eta_NCEP --- |-Aug_1990 -- |-Tier2_429 | |-Tier2_nobaja | |-Tier1_nobaja | | |-Tier1 | |-Tier2 |-Sep_1990 -- |-Tier2_429 | |-Tier2_nobaja | |-Tier1_nobaja | | |-Tier1 | |-Tier2 |-Oct_1990 -- |-Tier2_429 | |-Tier2_nobaja | |-Tier1_nobaja | |-ensemble -- (two files; ensemble.dat and the GrADS control file for the data) b) Additional runs Besides the runs required by the NAMAP project (hourly output and twice daily), we provide results from three additional runs (under directories Tier2_429, Tier2_nobaja, and Tier1_nobaja). The Tier2_429 run started at 12Z of April 29, 1990. Whereas the Tier2_nobaja run means that the treatment for SST of GOC (Gulf of Cal.) was not included. The Tier2_429 run show much difference in precip between model simulations and observations. The run started at 00Z of May 1 (required by the NAMAP) has the best agreement with observations. Tier1_nobaja means that the run is output to Tier1 and the treatment for GOC was not included. We integrated the model starting from different initial times (3 12Zs and 200Zs; they are 1 day and 12 hrs apart). The Ensemble members are 12Z, April 23, 00Z April 25, 12Z April 26, 00Z April 28, 12Z April 29, and 00 May 1 respectively. The data file under subdirectory ensemble provide ensemble mean of total precip for 6 months (May-Oct). c) Data specs The output data have a resolution of 0.25 x 0.25 degree (already grided) and can be read by GrADS software (see tier1.ctl and tier2.ctl for details). Except data under ensemble directory (where the Grads control is provided). The domain is the exact size required by the NAMAP (tier1 or tier2).The data are big endian IEEE binary. Please refer to the control file for more details. d) Filename convention Under each Tier1 subdirectory are the files for Tier1. They are (the numbers in front of the filenames are the size of the file). 236 SH_24 236 q700_24 236 v700_24 236 CAPE_24 236 SLP_24 236 q850_24 236 v850_24 236 DLR_24 236 T700_24 236 q925_24 236 v925_24 236 DSR_24 236 T850_24 236 qsfc_24 236 vsfc_24 236 LH_24 236 T925_24 236 u700_24 236 z700_24 236 OLR_24 236 Tsfc_24 236 u850_24 236 z850_24 236 OSR_24 236 cldconv_24 236 u925_24 236 z925_24 236 PWcol_24 236 cldlg_24 236 usfc_24 236 zsfc_24 Under Tier2 (including Tier2_429 and Tier2_nobaja) are files for Tier2 116 Tdew250_2 116 u300_2 116 v850_2 116 SLP_2 116 Tdew300_2 116 u500_2 116 v925_2 116 T100_2 116 Tdew500_2 116 u700_2 116 vsfc_2 116 T200_2 116 Tdew700_2 116 u850_2 116 z100_2 116 T250_2 116 Tdew850_2 116 u925_2 116 z200_2 172 T300_2 116 Tdew925_2 116 usfc_2 116 z250_2 116 T500_2 116 Tdewsfc_2 116 v100_2 116 z300_2 116 T700_2 116 Tsfc_2 116 v200_2 116 z500_2 116 T850_2 116 precip_2 116 v250_2 116 z700_2 116 T925_2 116 u100_2 116 v300_2 116 z850_2 116 Tdew100_2 116 u200_2 116 v500_2 116 z925_2 116 Tdew200_2 116 u250_2 116 v700_2 116 zsfc_2 The filename convention suggested by Dave was used except in the Tier2 runs where we output Tdew (Dew point temperature) instead of q. So Tdew for 8 levels replaced q for 8 levels. Also in the Tier1 run, we did not output LWnet_24, albedo_24, and qucol_24, and qvcol_24 directly. They are needed to be computed using the variables we provided (OLR_24: outgoing longwave radiation; DLR_24: downward longwave radiation; OSR_24: outgoing shortwave radiation; DSR_24: downward shortwave radiation. Also we provided q, u, and v separately).
