01:20 PM TM5-MP Feature #444 (Closed): Smoothing the application of CH4 surface constraints between different months
Past analysis of the CH4 emission estimates available in the chemical budget files shows that for e.g. 50-70S there c...
01:10 PM TM5-MP Feature #443: Smoothing for nudging of stratospheric ozone and CH4
New arrays introduced and tested to allow smoothing for O3 and CH4, where the CH4 uses the climatological file from H...

01:04 PM TM5-MP Feature #443 (Closed): Smoothing for nudging of stratospheric ozone and CH4
The smoothing approach for nudging stratospheric boundary conditions of O3 and CH4 will be updated to follow that int...
01:01 PM TM5-MP Bug #430 (Closed): Stratospheric nudging of CO and HNO3
01:00 PM TM5-MP Bug #430: Stratospheric nudging of CO and HNO3
The smoothing approach introduced removes the zigzag monthly nudging terms for HNO3 exhibited in the original UARS ra...

01:27 PM TM5-MP Bug #430: Stratospheric nudging of CO and HNO3
A new relaxation technique is applied to smooth the transition between months for the ODIN climatologies. The monthly...

10:46 AM TM5-MP Bug #430: Stratospheric nudging of CO and HNO3
For the CO/O3 ratio if the ODIN flag is FALSE it reads the UARS HNO3/O3 ratio !!
Looks like a copy and paste error...

01:53 PM TM5-MP Bug #430 (Closed): Stratospheric nudging of CO and HNO3
The ratios of CO/O3 and HNO3/O3 from the ODIN climatologies are calculated offline and stored as 1x1 zonal means in i...

01:15 PM TM5-MP Bug #400: Too low cloud effective radius with Martin parameterization.
The global_eff_radius(i,j,l) array was given a value of 6.0 during initialization at every time-step which has been c...
