Paul: I have put 3 time-gcm netcdf history files on the hao ftp site ftp://ftp.hao.ucar.edu/pub/foster/hays These files contain 3d model results on the time-gcm grid: foster ftp 40610492 Oct 9 09:33 ROBLE.tgcm24d.sdshays.nc foster ftp 40610492 Oct 9 09:33 ROBLE.tgcm24d.seqhays.nc foster ftp 40610492 Oct 9 09:33 ROBLE.tgcm24d.sjshays.nc I have also put output from the netcdf command "ncdump" for each of the files in the same /pub/foster/hays directory (*.ncd). These are text files describing the contents of the *.nc files. sdshays files are for december solstice, seqhays files are for march equinox, sjshays files are for june solstice. I made some runs of our post-processor, and saved *.cgm and *.ps files, also on the ftp site: foster ftp 4178880 Oct 9 09:33 sdshays.log.cgm foster ftp 4518720 Oct 9 09:33 seqhays.log.cgm foster ftp 4222080 Oct 9 09:33 sjshays.log.cgm foster ftp 10089549 Oct 9 09:33 sdshays.log.ps foster ftp 10981610 Oct 9 09:33 seqhays.log.ps foster ftp 10209962 Oct 9 09:33 sjshays.log.ps These are horizontal maps and vertical slices of the fields. (vertical slices are plotted in log10) The ps files have same plots as the cgm files, so you can use either. The 3-d fields on the histories are: TN : neutral temperature (note that bottom boundary of TN is stored at the top level) XO2N: O2 number density XO3N: O3 number density XON : O number density EO200A: O2 (0-0) band emission XLO : O21SIG: O2(1SIG) number density O2 : O2 mass mixing ratio O1 : O mass mixing ratio Z : geopotential The O2 emission was calculated as follows: c Given tn, xo2,xo,xn2 (species in cm-3), dimensioned id, return c O2 (0-0) band emission: c (from Ian McDade, (mcdade@windic.yorku.ca) Mar 7, 1994 mail c communication to Roble) c c The nighttime O2 Atmospheric (0-0) band emission rates in the region may be c similarly modelled using: c c A1 k1 [O]^2 {[N2]+[O2]} [O2] c Vat=--------------------------------------------------(photons cm-3 sec-1) c {A2 + k2a[O2] + k2b[N2] + k2c[O]} {D'[O2] + D"[O]} c c where [O], [O2] and [N2] are number densities cm-3 c A1 = 0.079 sec-1 c A2 = 0.083 sec-1 c k1 = 4.7E-33 (300/T)^2 cm6 sec-1 c k2a = 4.0E-17 cm3 sec-1 c k2b = 2.2E-15 cm3 sec-1 c k2c = 8.0E-14 cm3 sec-1 c D' = 6.6 dimensionless c D" = 19 dimensionless c dimension tn(id),xo2(id),xo(id),xn2(id),fout(id) parameter(a1=.079, a2=.083, rk2a=4.e-17, rk2b=2.2e-15, + rk2c=8.e-14, dp=6.6, dpp=19.) c do k=1,id rk1 = 4.7e-33*(300./tn(k))**2 fout(k) = (a1*rk1*xo(k)**2 * (xn2(k)+xo2(k)) * xo2(k)) / + ((a2 + rk2a*xo2(k) + rk2b*xn2(k) + rk2c*xo(k)) * + (dp*xo2(k)+dpp*xo(k))) enddo I'm assuming you have experience reading netcdf files. If you need any help, let me know. I can also make more runs of the post- processor -- could make ascii data files of specific slices if you want. Let me know when you have copied the files so I can free that disk. Good Luck, --Ben
