New CHEM2D scheme for NOGAPS-ALPHA

• Since CVS is down, you can get updated files via
  thresher/home/mccormack/nogaps/nogaps_chem2d_v1.0
  .tar
• put chem2d_coeff_v1.0.dat in your climdir
  contains 3 terms (P-L), d(P-L)/dr, and d(P-L)/dT
• when o3scheme1.0 in jobscript, diabat.f calls
  chem2d.f to read in chem2d coeffs and interpolate
• diabat.f calls cariolle.f to get climo temps
  (aka CD86 coeff 5), then calls o3_chem2dnew.f to
  update o3t
• Do we want to use CIRA/URAP temps instead of
  CD86 temps? What are good ways to test the new
  temp term?

Including temp. coeff changes O3 mr at 10 hPa by
at most 10 for this January case.

HPC Issue 1read_noghist for T239 on hpc11

• Currently cant run read_noghist spectral history
  file inverter on t239 output on hpc11. Problem
  seems to arise at/near call to transr.f ? SCSL
  library routine.
• Can run read_noghist on hpc11 using t79 output.
  ? Memory problem?
• We cant run any read_hoghist jobs in HPC queue.
  Must run interactively. Default memory allocation
  on ruby is MUCH bigger than on hpc11. Havent
  been able to increase this with limit command.
• We should probably figure out how to run these
  jobs in the queue somehow. In the meantime, will
  experiment further with compiler options and
  libraries, then ask MSRC for help.

HPC Issue 2NASA Project Columbia

• Do we want to apply for HPC hours through this?
  Deadline is 14 Jan 2005.
• Project Columbia has 20 512 processor (Intel
  Itanium 2) SGI Altix with 440 TB storage.
• Awards are for NASA projects funded through
  Science Mission Directorate (NOGAPS-ALPHA Aura
  validation, GW investigations?)
• Proposal cover sheet, abstract, computing
  requirements (processor hours, memory, etc), and
  3-page tech proposal required. Also need program
  managers signature (?).
• Like DoD HPC, one person acts as PI, and if
  approved all additional accounts are obtained via
  request forms through PI.
