Global Parallel Experiment Change Log

Experiment Name:  Summer 2000 analysis changes

When Who What
2000/06/28/00 Iredell Parallel terminated since it was not performing well.
2000/06/23/00 Derber Modify AMSU-A qc to account for cloud liquid water influence on observation. Include qc for future use of AMSU-B.
2000/06/11/00 Treadon NOAA-15 HIRS/3 radiances turned off in operations due to increasing bias in observations. Keep HIRS/3 data in parallel.
2000/06/07/12 Iredell Recopied guess (but not bias correction) from operations for a fresh start.
2000/06/06/12 Iredell An old (July 1999) forecast model was being used in the GDAS cycle. The parallel will now use the operational model.
2000/06/05/12 Treadon Various changes to SETUPRAD: (1) tighten channel 8 qc limits, (2) reduce channel 9 error bounds, (3) turn off ozone sensitivity for all hirs and goes channels when channel 9 is not used.
2000/06/01/12 Iredell Begin parallel run. Guess copied from operations but bias correction taken from previous PRX. Some changes have been made to the SSI in the radiance analysis from the previous PRX version.
