Hi Ferret community,
I have two different versions on pyferret: V7.1 on my Mac OS X El Capitan and V.7.5 on a Linux Red Hat workstation. The reason I retained the previous version of pyferret on my Mac was to be sure that my old analysis scripts would run flawlessly if there were differences when upgraded to the newer release. Having been working between the two different systems I have noticed two differences that have impacted my figures / analysis. I am going to split this into two separate emails since these topics are not related.
The first issue regards how the two versions handle the proleptic gregorian calendar:
when reading in the same exact file.
Using Pyferret V7.1 on OS X El Capitan:
list siconc_gt_15[d=3,l=1,x=1,y=1]
VARIABLE : CURV_TO_RECT(SICONC_ONLY[D=1], MAP[D=2])
FILENAME : siconc_SImon_MPI-ESM1-2-LR_historical_r1i1p1f1_gn_198601-200512_1x1_regrid_only_gt_15.nc
LONGITUDE: 0.5E
LATITUDE : 0.5N
TIME : 16-JAN-1986 12:00
....
say `siconc_gt_15,return=calendar`
!-> MESSAGE/CONTINUE GREGORIAN
GREGORIAN
Using Pyferret V7.5 on Linux RedHat
yes? list siconc_gt_15[d=1,l=1,x=1,y=1]
VARIABLE : CURV_TO_RECT(SICONC_ONLY[D=1], MAP[D=2])
FILENAME : siconc_SImon_MPI-ESM1-2-LR_historical_r1i1p1f1_gn_198601-200512_1x1_regrid_only_gt_15.nc
LONGITUDE: 0.5E
LATITUDE : 0.5N
Thanks ahead of time for any insight,
Becki
